Use Video for live video images. Video supports both spatial and temporal compression. Temporal compression is enabled by activating key frames. For best video quality, set your key frame option to match your sample rate. The compression and decompression speed varies with CPU performance.
Performance degrades as the CPU and disk speed decrease.
Cinepak Cinepak, or Compact Video, is a scheme similar to the Video compressor but is considerably slower. Cinepak's decompression speed is faster than the Video compressor. Decompressing the image takes less than a second. SuperMac, manufacturer of Cinepak, recommends a key frame rate of 7 for optimal playback. When using the Cinepak compressor for playback on CD-ROM, you can specify the data rate limit in the Motion settings region of the Compression Settings dialog box.
