Inappropriate for video-based movie playback. Very fast compressing and decompressing of video. Good compression ratios. Use for real-time capture of video, particularly when hard disk space is at a premium, or for testing clips. OK for hard disk playback.
Image quality is poor when compressing enough for CD-ROM playback.
Commonly used for video movies that require CD-ROM playback. Very slow compressing, but decompresses fast on low-end processors. Good choice for streaming. A high-quality compressor. Good for capture on AV computers and as intermediate storage format.
