Setting Video for Windows compression optionsWhen setting Video for Windows compression options, you can specify the compressor and compression quality. Compressors available for Video for Windows include Microsoft Video 1, Cinepak, Microsoft RLE, Microsoft DV, and Intel Video. Choose a compressor based on the type of original images you have and the purpose of the rendered movie: Cinepak Use when compressing 16-bit and 24-bit video for playback from CD or for desktop presentations. For best results, use the Cinepak compressor on raw source data that has not been previously compressed with a highly lossy compressor. Note that this is a slow compression method. With Cinepak, decompression is much faster than compression, and the data rate for playback can be defined by the user. However, you cannot save an alpha channel using the Cinepak compressor. Microsoft RLE Use for lossless compression limited to 256 colors. Microsoft DV Use for digital video camcorders. Intel Indeo/Microsoft Video Use when compressing video for playback from CD. Full Frames (Uncompressed) Use for a depth setting of Millions of Colors+ when an alpha channel is required. To specify Video for Windows compression settings:
