[Tutorial] DivX 5.0x encoding setup full manual DivX 5.0x encoding setup full manual with the currently popular programs compressed DVD, eventually encounters to call DVIX encoding kernels. I take DVIX5.0x as an example, detail its settings. 1, Divx Codec Setup: Variable Bitrate Mode "1-pass" is equivalent to "low motion" of Divx 3.11 Alpha. "1-pass QUALITY BASED" is a constant code rate code (unchanged per frame rate). "2-pass" is the best coding method. (The film has the smallest size, the picture quality is best.) But more than "1-pass" more coded time. It automatically adjusts the code rate according to the picture. Encoding Bitrate Sets the video code rate. 1500 will get a good picture quality, there is no need to exceed 2000, but don't be less than 600 (the picture is very bad). If the movie is pressed to 1CD, it is recommended to use 1300 to 2000 with 700 ~ 1000, 2CD. TWO-Pass Encoding Log Files log file - "2-pass" mode When you encode, you need to specify a location to store temporary encoding information files. MV FILE - Store vector information can accelerate encoding. MPEG4 Tools (Select this item reduces the coding speed) Use quarter pixel - improves the picture resolution. Use GMC (Global Motion Compensation) - Full dynamic compensation, is very helpful to improve the quality of the big dynamic picture. Use bidirectional encoding - two-way decoding, allowing B frames to be inserted between I frame (picture information) and P frames (forecast frames), can improve the picture quality. Write Divx MP4 File gets a video file that is fully compliant with MPEG-4 specification, but it is no sound, so don't go to it! 2, General Parameters Setup: Enable CROP Screen Trimming, you can go to the black edge of a wide silver movie (they will occupy the code rate), and the compression tool you usually use will also have this option. ENABLE RESIZE registration size. Psychovisual Enhancement removes the visual insensitive picture, a bit like compressed MP3 theory. The volume of the movie file can be reduced. Premonishing Source Screen Noise Reduction. If the source is DVD, don't choose it. KeyFrame Max KeyFrame Interval - Maximum Key Frame Page Spacing. Options for improving the smoothness of the screen. When you play movies, keyframes help you oriented to the screen you want to search. Generally encoded, it will be automatically inserted into each scene. When you encounter the playback, you must manually adjust. (For example, 29 frames per second, you think there is a keyframe every 10 seconds, then add 290.) Scene Change Threshold - This is 50%. Source Interlace Select All Frames Are Progressive, watching movies on your computer, Basic Video Deinterlace is not hooked. 3, Advanced Parameters Setup: Date Rate Control (RC) These settings are important for determining screen quality. Maximum Quantizer - a large number of values such as 20, indicating increasing compression, but the picture is not good.
