Cinepak allows temporal and spatial compression, as well as data rate limiting. CPU-intensive processes usually slow down other processes running on the same computer, and may not run very well, if at all, on slower computers.
Intranets are typically faster and more stable than external networks, such as the Internet.
Keyframes contain the complete video image, while delta frames contain only the changes between keyframes. Lossless codecs include the Animation codec and the None codec. Cinepak and JPEG are lossy codecs.
