Premiere video filter detailed
-------------------------------------------------- ------------------------------
1. Brightness & Contrast (Brightness and Contrast) This video filter effect will change the brightness and contrast of the picture. Similar to the brightness and contrast of the television, the adjustment here is the movement of the slider, 2. Channel Mixer uses this video filter effect to modify a color channel with a synthetic value of several color channels. Using this effect, you can create a color adjustment effect that uses other color adjustment tools. By selecting a high quality gray image, create high quality tan or other tones by selecting a high quality gray scale image from each of the color channels. Image, has been exchanged or copied, 3. Color Balance This video filter effect utilizes a slider to adjust the RGB color allocation ratio, so that a color is high to adjust its brightness. This filtration belongs to a trick, 4. CONVOLUTION KERNEL This video filter effect uses a lack of mathematical expressions, input data to the internal expression through the matrix text to calculate the scroll value of the surrounding pixels of each pixel, which further enriches the video effect. You can modify the data mode from the supplied mode menu, you can also re-enter the new value (as long as the effect is considered to be in the Convolution Matrix text box, the center number is the brightness calculation value of the pixel (the number entered) The brightness value of pixels is multipined, the surrounding number is the calculated value required by the pixels around the pixel, and the value entered in this box will multiply the brightness value of the surrounding pixels. Scale in the Misc (Miscellaneous) frame The number input in the text box will be used as the divisor, the pixel point includes the sum of the pixel points of the surrounding pixel point and the input to the "data matrix of the environment center pixel point", the divisor is divided. TheOffset text box is an offset of a calculation result Quantity (adding the result of the company). All values allowed input ranges, can be from -99999 ~ 999999, but do not have such a large use, if the demo is effect, if the defined set of data is very practical And later in the future, click the Save button to store it, and remember the folder and file name (or store it on the floppy disk). Next time it is loaded into the current data definition format next time You can use it. If you want to use the internal image conversion data format, click the button above the middle of Figure 7-20, select the appropriate option from the pop-up menu. The constant image conversion data format is very useful tool, it It can make the image vague or clear. In order to fully explain the problem, Figure 7-21 lists several typical results for reference. This is a typical representative selected from Figure 7-20. These video effects are making still pictures It is very useful when special programs. It is similar to the filtering effect in Adobe Photoshop, just here for movie production, if you don't understand the exemption of premiere, you may think of using Photoshop to process. And if you take a photo via Photoshop After processing, it is used for film production. It is bound to waste the waste and time waste. It can be seen here. 5.extract (extraction) When you want to use a color picture as a mask, it should It converts a gray scale picture. With this video filter effect, you can choose the grayscale level to achieve more practical effects. Figure 7-22 is a dialog box for extracting the mask component of the video segment. There are 2 slip Block, 2 black 3 corners with drawing used to select the converted white grayscale in the original picture, Softness slider is used to adjust the softness of the picture. You can have passed through the Invert check box. Set grayscale picture for reverse phase.
The black ladder chart (in reverse phase) changes in the lower left corner change as Softness slides, when it becomes a triangle, it indicates that the effect of the original picture is reached; when it is a trapezoid, it indicates that the bright and dark boundaries of the original picture have been changed. . 6. Levels This video filter effect combines the brightness of the screen, contrast, and color balance (including color inverted), etc., more convenient to improve the image quality and effect of output screen. Figure 7-23 is an adjustment dialog. In Figures 7-23, the RGB, R, G, and B channel can be selected as modified objects via the RGB channel selection menu, and the RGB channel can be used by default. The intermediate portion of the left is the color, pixel distribution line diagram of the original picture. The horizontal direction of the line map indicates the brightness of the pixel from left to right, and the left is 0 (darker point), the right side is 255 (brightest); longitudinal direction represents a total number of pixels. Therefore, the closer to the grafting of the left, the darker pixel point is indicated, the more close to the right, and the brighter pixel point is indicated. The steps to adjust the brightness and contrast using the Levels dialog box: (1) Use the three sliders under the line diagram, or enter the specific value in the Input Levels text box, adjust each color take-up. If you need to increase the brightness, you should move the white triangle to the left. Convert the white triangle to the right; if you need to increase the image shadow, you should move the black triangle to the right, and turn the black triangle to the left; if you need to adjust the gray level, Gray triangles should be moved properly. Note: Do not set the gray slider to the black slider to coincide, otherwise it will become 2 sliders. (2) Adjust the contrast of the screen output, use the two sliders of the screen, or enter the specific value in the Output Levels text box to adjust the contrast. If you need to increase the brightness of the black area of the screen, you should move the black triangle to the right; if you need to reduce the brightness of the white area of the screen, you should move the white triangle to the left; if you want to use a reverse color, you should slip black and white Block interchange position. (3) Want to save the settings to be used later, click the SAVE button. Click the Load button to be loaded with the stored file, define the format * .lvl. (4) After the setting is complete, click the OK button. 7. POSTERIZE (Multi-Color Score) This video effect can reduce the number of colors in the original picture, only the basic red, green, blue, and yellow colors remaining; finally convert the color in the original picture like advertising Medium color. It is a video effect that changes over time. 7.3.2 BLUR video filter effect group BLUR video effect group includes 7 video effects. 1. Antialias (anti-aliasing) This video filter effect is to make a significant portion in the image area, so that the picture is softized. Adding appropriate colors from the transition area from dark to bright, the region image becomes blurred. 2. Camera Blur (Camera Blur) This video filter is a fuzzy adjustment method that changes over time, allows the screen from the clearest continuous adjustment to more and more blurred, as if the camera adjusts the fuzzy scene when the camera is adjusted. This video filter effect can be applied to the start screen of the segment or end the screen, and the effect of focusing. To use the focusing effect, you must set the screen of the start point and the screen of the end point, as shown in Figure 7-27 is a comparison of 2 pictures of a focus process. This video filter effect has only one adjustment slider, allowing the start point screen and the endpoint screen to use the slider different locations to meet the requirements.
3. Directional BLUR (Directional Fuzzy) This video filter effect produces a directionally blurred sensation in the image, thereby producing a piece of fragment in motion. Direction (direction) specifies the direction of the blurring, step by step by the center of the wandere, all set to 180 degrees, and all settings to 0 degrees; Blur Length Specifies the degree of image blur. 4. Fast BLUR (Fast Blur) Use this video filter effect to specify how fast image is blurred. It can specify a blurred direction to be horizontally, vertical, or in two directions. The fuzzy effect produced by Fast Blur is faster than Gaussian Blur. 5. Gaussian Blur This video filter effect is extremely blurred by modifying the difference between the underside boundary. Its effect is as used as a number of BLUR or Blur More. Gaussian is a deformation curve generated by the color value of the pixel point of the picture. It can make the more sharp screen to make the screen have a haze effect. Figure 7-30 The right image is a comparison diagram before and after Gauss, where the left is the original picture. 6. GHOSTING (Ghost) This video filter effect transparently covers the currently played frame screen to the previous frame, resulting in a ghost attachment, sometimes used in movie stunts. 7. Radial BLUR This video filter effect allows the screen to generate radio rays (appropriately zoom) or rotary softening. Figure 7-31 is a ray softening setting dialog. Select the ZOOM radio button to flexibly form a radiating blur line; select the SPIN (rotation) radio button, the flexible mode forms a plurality of concentricular blur lines. Change the degree of blur by adjusting the Amount (quantity) slider or the input value (1 ~ 100). You can determine the fuzzy axis point in the display diagram (or drag). This video filter effect is changed over time. 7.3.3 Channel Video Filter Effect Group CHANNEL video filter effect group has only one video filter effect. Invert This video filter effect can convert the color of the picture into the opposite colors. For example, the white reverse in the original picture is black, and the red becomes green. 7.3.4 Distort Video Filter Effect Group Distort Video Filter Effect Group has 11 video filter effects, as shown in Figure 7-34. 1. BEND (bending) This video filter effect will be bent in the picture of the movie piece in horizontal or vertical direction. Sinus, circle, triangle, or square (Square) can be selected as a waveform (WAVE) of the bending deformation. And the slider is used to adjust the video filter effect in the horizontal direction (Vertical) in the horizontal direction (Vertical), the adjustment parameter has INTENSITY (Deformation intensity), Rate (rate) and width (width), as shown in Figure 7 35 shown.
At the same time, in the horizontal direction, the direction of movement directions to the waveform is LEFT (left), Right (inward), OUT (outward), in the vertical direction, can select UP (up), DOWN ( Down), in (inward), ON (outward). 2. LENS DISTORTION This video filter effect can be distorted by the original shape. Through the adjustment of the slider, the picture is made of surface, and the horizontal is curved, the horizontal is curved, and the left and right pleats and vertical pleats, etc.. Comprehensive use of the respective distorted deformed sliders, the screen can be made like the deformation effect of the haha mirror. Figure 7-36 is a lens distorted deformation video filter effect setting dialog. 3. Mirror (mirror) This video filter effect enables the screen to appear symmetrical images, which takes a symmetry axis in the horizontal direction or vertical direction, holds the image on the left side of the axis, supplemented by the image on the left, as symmetrically The mirror direction is in general.
In practical applications, by selecting horizontal or vertical buttons, the direction of the mirror symmetry is changed; the position of the symmetry axis can be adjusted through the "mirror boundary line indicator and adjusting slider" (currently on the top, If you select vertical, it is on the left). And by selecting the LEFT, RIGHT, TOP, BOTTOM options to determine the reflective surface to showcase the image effect of different orientations. 4. PINCH This video filter effect can extend the central portion of the screen to the edge, thereby causing a spherical effect of the screen as a projection; or the surface of the screen is contracted to the screen to form a spherical effect of the screen depression. There is a slider, adjusting the percentage of the screen extension or contracted in the setup dialog box. It is a video filter effect of time varying time. Polar Coordinates This video filter effect can convert the original picture from the right angle coordinate to a pole session, or converted from a pole seat to a right angle coordinate 6. Ripple This video filter effect allows the screen to form a fluctuation effect, very like a corrugated motion on the water. The ripples can be selected from sinushes, circle, triangle or squares (Square). The slider is used to adjust the fluctuations in horizontal direction and vertical direction (Vertical). The adjustment parameters are: Intensity, rate (RATE), width (Width). Figure 7-41 is its adjustment dialog. At the same time, in the horizontal direction, the direction of movement of the waveform can be specified: to the left (LEFT), Right (Right), inward (in), OUT. In the vertical direction, the moving direction is selected: up (UP), down, inward, outward. It has the same place as Bend, but is different from behind in the output screen. 7. SHEAR (shear) This video filter effect causes the screen along a longitudinally varied curve. Start it is a straight line, you can create several control points on it. Drag the control points to different locations, the screen changes with the adjustment of the curve. To remove a control point, you should drag it to the range. If the adjustment is very bad, you can use the RESET button to return to the beginning. It is a video filter effect that changes over time. In Figures 7-42, the Wrap Around radio button can be wrapped to fill the empty outflow generated by the deformation; select the Repeat Edge Pixels radio button to move the color of the pixel in the extending direction of the pixel along the edge of the screen. stretch. When the pixels are multiple colors, a beautiful band can be formed. 8. Spherize This video filter effect will perform spherical projections or depression in the maximum inner cut circle of the screen, and change the deformation strength (-100 to 100) by adjusting the slider. If you do not want to use normal (Normal) variations in horizontal and vertical directions, unilateral (horizontal or vertical) can be deformed. Figure 7-43 is an adjustment dialog using a normal deformed manner, and the current deformation intensity value is the largest. It is a video filter effect that changes over time. 9. Twirl (Swirl) This video filter effect will make the screen swirls from the center, the more severely rotating the center.
As shown in Figures 7-44, the angle of the vortex can be adjusted by moving the slider or the input value (-999 ~ 999). The preview box on the upper part of the dialog displays the effects of the current settings. 10. Wave (waves) This video filter effect will allow the picture to form wavy deformation effects. Figure 7-45 is its setup dialog. There are 3 main parameters in the figure to adjust the slider: the waveform generator adjusts the slider to generate the shape of the wavy, ie the number of waves (1 ~ 999); the wavelength adjusts the slider to adjust the distance between peaks (1 ~ 999); Amplitude adjusts the slider to adjust the degree of bending deformation of each wave (1 ~ 999). In addition to 3 main parameters, it can control the percentage of the waveform in the horizontal and vertical direction, and the type type TYPE (there is a sine wave, triangle, square wave, 3 selected buttons, etc.) .Zigzag This video filter effect will cause the screen to deformed along the radiation direction, the deformation effect can be adjusted. Figure 7-46 shows its settings dialog. Enter in the Amount in the dialog box. Values (0 ~ 100) or adjust the size of the slider to set the amount of deformation. Use the RIDGES text box or the slider to set the number of zigzag waves formed from the center to the edge (1 to 20). In addition to the MODE option There are 3 picture pixel offset: Pond Ripple is a pond corrugated, Out from center offers pixels from the center to the edge, the Around Center item can rotate the pixel with the center of the picture. This video filter is changed over time. .7.3.5 Image Control Video Filter Effect Group Image Control Video Filter Effect Groups There are 8 video filters. 1. BLACK & WHITE (black and white) The role of this video filter effect will make the color picture of the movie pieces A black and white image of a grayscale stage .2.Color Balance (HLS) (color balance) This video filter effect can change the color of the color picture of the movie, brightness (Lightness), and saturation (Saturation.3. Color Offset This video filter effect can adjust a channel (red, green, blue) in the RGB3 channel, so that the channel can be up (UP), down (down), left (left), To the right (Right), this video filter is prepared for making stereo movies, and the stereo movie should wear a dedicated filter glasses to see the stereo effect. Use this video filter effect will be generated 2 Different color screens .4.Color Pass This video filter effect can convert the other parts of a single specified single color in a piece to a grayscale image. You can use this effect to brighten the pieces. A specific area. A color can be selected by a palette or use a straw tool to absorb a color on the original screen as the channel color. By adjusting the slider to change the range of use (expand or shrink). The characteristics of time change can be made by transitional effects on color level.
5. Color Replace This video filter effect can be used to change the color in the picture in a color, so that color replacement video filter effect is called. With this manner, the local color or all of the same colors can be converted. You can also use the characteristics of time change, make the changing effect of color levels. Unlike the Color Pass, it keeps the color component that is not replaced in the original screen, and only painted or dyed the neighborhood. Figure 7-52 is a setup dialog for color replacement video filter effect. 6. Gamma Correction (grayscale correction) This video filter effect The image produces a relatively bright or dimmed effect by adjusting the contrast of the image. It is made by correcting color or equivalent to medium grayscale, rather than being implemented by increasing or reducing the brightness of the light source. 7. Medina This video filter effect can replace each pixel with RGB average of its surrounding pixels. 8. Tint (color) This video filter effect will add some colors on the screen to the segmentation formation of the composite color screen. Select some color from the palette by clicking the color sample box; adding a color percentage (1 to 100%) by the slider adjustment (1 to 100%). It is a video filter effect that changes over time. Therefore, the next color of the original picture can be made to another color transition. 7.3.6 Perspective Video Filter Effect Groups Perspective Video Filter Effect Group has 5 video filter effects. 1. Basic 3D (Basic 3D) This video filter effect is operated in a virtual three-dimensional space. The image can be rotated about horizontal and vertical shafts and move the image in a manner near or away from the screen. The basic three-dimensional effect can also be created, and a mirror highlighting is also created, producing a light from a rotating surface to reflect the effect. The light source of the mirror highlight is always on the top, back and left. Because the light comes from above, the image must be tilted back to see the reflection effect. This enhances the authenticity of the three-dimensional effect. Swivel, control horizontal rotation (rotating around a vertical axis), rotating 90o degree of the image can be seen on the back surface, which is the image image front of the image; TILT controls vertical rotation; Distance to Image (to image Distance) Specifies the distance from the viewer. With the increase in distance, the image will be backward; the Specular Highlight (Mirror Highlighting Area) adds a bunch of flashing light reflected from the rotating layer, as if it is a light source located on the top of the head; Preview (preview) display three-dimensional image line frame. Select this option to speed up display; if you want to watch the final result, you should cancel the selection of this item. 2. Bevel alpha (tilt alpha) This video filter can produce a cacheed stereo effect for the alpha boundary of the image. If there is no ALPHA channel in the disc, or its Alpha channel is completely opaque, the effect will be applied to the edge of the piece. The edges produced using this effect are more soft than those with the Bevel Edges effect. 3. BEVEL EDGES This video filter effect can generate a three-dimensional effect for the edge of the image. The edge position is determined by the edge image ALPHA channel. Unlike the bevel alpha effect, the effect of using Bevel EDGES is always rectangular, as shown in Figures 7-60, so the image with non-rectangular ALPHA channel will not produce the correct display. All edges have the same thickness.
4. Drop Shadow This effect adds a shadow display behind the pieces. The shape of the Drop Shadow is determined by the alpha channel of the piezage. Unlike most other effects, this effect can create an impact outside the boundary of the piezage. 5. Transform This video filter effect can apply 2 dimensional geometric deformation to the segment. Use it to incline the piece along any axis 7.3.7 PIXelate video filter effect group Pixelate video filter effect group has 3 video filter effects. 1. Crystalize This video filter effect can make the color pattern of the current picture form a crystal, and the number of crystals can be set by slider. It is changed over time, so it can set the crystalline effect of the start point and the end point screen. Figure 7-63 shows the case where the screen uses the crystalline effect. 2. Facet This video filter effect will bind the pixels with similar color into a polygon, producing the effect of gem carving painting. 3. Pointillize This video filter effect can disperse the color of the picture, with a point to replace the smooth screen. You can adjust the size of the scatter by the slider (3 ~ 300 pixel points), the smaller the point, the more you can exhibit the original screen. The general picture scatter is 8 or more, and the original picture cannot be expressed, only a random graphic block can be exhibited. It is a video filter effect that varies over time. Note: If the size is used in the movie output, the movie dynamic changes and use countless color scatter points, even the average estimation time is exceeded. 7.3.8 Render Video Filter Effect Group Render Video Filter Effect Group There is only one video filter effect. 1. LENS FLARE (lens halo) This video filter effect can be filtered out of the aura with three lenses, and the light of different intensity is emitted from a certain position of the picture. It is a video filter effect that changes over time. The starting position and end position of the light can be set to express the lens light source movement process. It can be adjusted to set the filter after filtering through the Brightness slider. Click on a location in the figure to determine the location of the new light-emitting point. There are three types of filter lens options below the preview window, which can be used freely. 7.3.9 Sharpen Video Filter Effect Group Sharpen Video Filter Effect Group has 3 video filter effects. 1. Gaussian Sharpen This video filter effect passes the difference in the image by modifying the difference in the darkness, and the image is extremely sharp, opposite to Gaussian. Its effect is equivalent to using several Sharpen or Sharper More. 2. Sharpen This video filter effect can cause significant contrast effects between adjacent pixels in the screen, so that the image looks clearer. 3. Sharpen Edge This video filter effect can cause more obvious comparisons between the pixels in the screen, make the image look clearer, 7.3.10 STYLIZE video filter effect group STYLIZE video filter effect group There are 12 video filter effects. 1. Alpha Glow (Alpha Glow) This video filter effect only works on a piece of ALPHA channel and is only role in the first Alpha channel. It can generate a color gradually attenuated or to another color transition in an alpha channel specified. The parameter setting dialog is shown in Figure 7-73. Where Glow is used to adjust the current light-emitting color value, the Brightness slider is used to adjust the brightness of the ALPHA channel area of the picture. Set the start value and end value of the additional color via the Start Color and the End Color color stick box. This is a video filter effect that varies over time.
2. Color EMBOSS This video filter effect does not suppress color in the original image, the other effect is the same as the EMBOSS. 3. EMBOSS (relief) This video filter effect is based on the color of the current picture and the color is desal, mainly using the grayscale level to form a relief effect. 4. Find Edges This video filter effect can be circulated on the edge of the color screen, and the edge is not shown in the grayscale image. 5. Mosaic (Mosaic) This video filter effect is in the middle of the mosaic mosaic pattern instead of the source screen in accordance with the color level of the picture. By adjusting the slider, the size of the mosaic pattern can be controlled to maintain the face of the original picture. At the same time, you can choose a sharp picture effect. This video filter effect changes over time. 6. NOISE (noise) The video filter is randomly changing the value of the pixels in the entire image. Figure 7-78 shows the setting options for this effect and the results thereof. The degree of noise (0% to 100%) can be specified by the Amount of Noise option. When you select the USE Color Noise option, you can randomly change the red, green, blue value of the image pixel, otherwise the value of three primary colors in all color channels is the same. The clipping option determines whether the noise is distorted by pixel color. When the clipping option is selected, the image can be identifiable even if the 100% noise value can also be identifiable. If you want a fully random image, close the clipping option and open the Color Noise option. 7. Replicate This video filter effect can be copied to the screen to display up to 4 to 256 identical pictures on the screen. You can make a screen background with this video filter effect. 8. Solarize This video filter effect can be mixed along the direction of the positive and reverse screen, and select the color of the colored color by adjusting the slider. It is a video filter effect that changes over time. 9. Strobe Light This video filter effect can arouse an arithmetic operation at a certain period or randomly. For example, a piece is broken every 5 seconds, and it is displayed for 0.1 seconds; or the segment color is reversed at a random time interval. Its parameter settings and effects. Blend with Original Specifies the intensity or brightness of the effect. The larger value will reduce the strength of the effect. Strobe Duration Specifies the time length of the effect of the effect in seconds; Strobe Period specifies the duration between the effects after the start application is specified in seconds. For example, if the Strobe Duration is set to 0.1 seconds, the Strobe Period is set to 1.0 seconds, then the interrupt is applied to the duration of 0.1 seconds, and the time does not apply for 0.9 seconds; Random Strobe probability specifies any given frame in the disc The possibility of this effect will be applied; Strobe specifies the way the application effect is. Operates On Color Only will apply this effect on all color channels. Make Layer Transparent, makes a breakdown when the application is applied; Strobe Operator When you select Operates on Color Only in the STROBE drop-down list box, specify the arithmetic operator, province COPY. 10. TEXTURIZE This effect makes a piece look like a material with other pieces. For example, a tree can look like a material having a brick and can control the depth and surface light source of the material.
11. TILES (Tiles) This video filter effect will make the picture into many squares, such as patchwork tiles. This video filter effect setting dialog is shown as shown in Figure 7-83. By entering the value (1 ~ 99) in the Number Of Tiles text box, the number of pieces of the segmentation screen can be changed. For the 4: 3 picture, if input 6, it will be divided in the vertical direction, and the transverse segmentation is 8 times. By setting maximum offset 1 to 99 to achieve the effect of the tiles recently patchwork complete rules. It is a video filter effect that changes over time. 4 single options in the lower part for selecting the color of the patchwork seam. You can choose the default white background color, the default black foreground color, the picture color, the reverse picture of the picture. 12. WIND This video filter effect will make the screen form a wind blown deformation effect. Figure 7-84 shows the setting dialog of this effect. You can select 3 wind types in the Method frame: Wind (light wind), BLAST (gust), Stagger, open the direction of the wind blowing in the Direction framework. 7.3.11 TIME Video Filter Effect Group Time Video Filter Effect Group has two video filter effects. 1. ECHO (echo) The video filter effect can combine multiple frames from different times in the segment. Use it creates a simple visual echo effect to a complex tug effect. This effect is only visible when there is an animation in the disc. By default, when applying the ECHO effect, any effect of the previous application will be ignored. If you don't want to ignore these effects, you can create a virtual piece first. Note: Echo Time specifies the time between the echthics in seconds. Negative values will be emitted from previously; positive value from the later creation echo; Number of echoes specify the number of ECHO effect combinations; starting intersity specifies the intensity or brightness started in the echo sequence; decay's intensity ratio; Echo Operator The operator is specified between the echo; the ADD combines the echo by adding the pixel value; Maximum combines the echo by taking the maximum pixel value in all echoes; MINIMUM combines the echoes by taking all the pixel values in all echoes; Screen By combining the echo clamp, it is similar to the ADD, but it is not so fast; Composite In make uses the alpha channel from the echo from the latter-preceding combination; Composite In Front uses the alpha channel of the echo From the previous combination . 2. POSTERIZE TIME This video filter effect can take a frame from a number of movie pieces a certain number of frame screens. If Frame Rate is 4, only 1 frame is selected in each 4 frames of the original movie screen. Since it is intentional, the picture has an intermittent feeling. 7.3.12 Transform Video Filter Effect Groups That has ten video filter effects in the Transform video filter effect group. . Camera View This video filter effect mitigates a piece from a different angle. That is, a sphere is imagined, and the object is located at the center of the sphere, and the camera is located on the surface of the sphere. By controlling the position of the camera, the shape of the segment image can be distorted. It is a multi-directional video filter effect that changes over time and has a perspective effect.
Longitude moves the camera in the horizontal direction, making the fragment horizontally rotate; Latitude (latitude) moves the camera in the vertical direction, so that the septal seems to be in vertical selection; ROLL (rotation) rotates the camera, so that the fragment is like a flat rotation Focal Length changes the focal length of the camera lens. The shorter the focal length, the wider the horizon; the longer the focal length, the view is narrowed, but the viewing angle is close; the distance specifies the distance from the camera to the sphere; zoom zoomed or reduced the pieces; Fill After the distortion leaves the fill color; Fill Alpha Channel Selects the check box to make the background transparent and easily superimpose the segment to other pieces. 2. CLIP and CROP These two video filter effects can cut the image edge due to the burrs caused by the digital picture capture card. With the slider, 4 are trimmed separately. When trim, you can set in units of pixels or percentage values. With this method, 4 blank edges will be left behind, and the edge portion cannot be eliminated, and can only be replaced with other homogeneous colors. If you want to keep the trim, you should use the CROP video filter effect to trim it. Clip and crop are all changing video filters with time, trimming is similar, and there is only differences in edge processing. One is to leave a blank side, one is automatically adjusting the size, so the application meaning is also different. Figure 7-89 and Figure 7-90 are the effect of these two trim results. It can be seen that the Clip trim technique can only be used on a piece with a smaller edge adjustment range, and it is necessary to need to be needed to do not color; and the CROP trimmer can obtain a local image by multiple acting on one image multiple times. The full screen effect is like a photo slice. 3. Horizontal Flip (horizontal flip) and Vertical Flip (Vertical Flip) This video filter effect turns about 180 degrees or up and down, as the reverse effect of the mirror. Still maintaining a positive order after the picture is rolling. 4. Horizontal Hold (horizontal synchronization) and Vertical Hold (Vertical Synchronization) This video filter effect can adjust the screen to the inclined picture, using the slider adjustment to pour the picture or up and down, as shown in Figure 7-92. It is a video filter effect that varies over time, so it can be set to the beginning of the screen as an inclined, and at the end screen is set to normal. It may be used in some movie stunts. 5. Image PAN (Image Slimming) This video filter is a typical video filter effect that is typically changed and is an imaging effect of analog camera lens. For example, in order to highlight some of the pictures, the lens flip can be performed from other parts of this picture, and gradually positioned on the protruding focus portions, as shown in Figures 7-93. Since it is an analog camera, even static pictures will also produce strong dynamic and remote perspective effects. Only because the resolution of the image is amplified to a certain extent, it will not be able to truly see a clearer realm. Using this video filter effect, the overlapping piece can be used to scroll over curtain design. In the source screen on the left of the Image Pan Setting dialog, the location and size of the segment can be set.
