Good-quality video playing at full screen [640 x 480) resolution with 24 bits per pixel) would have about 30 frames per second if you want it to play without any jerks. In terms of file size, it would mean that you can store only about 25 seconds of video data in a 650 MB CD without compression. The file size increases significantly if the video includes an audio stream as the audio is usually heavier than the video itself. Depending on how the audio is configured, it could be 150 times heavier than the video data.

For instance, 16-bit stereo audio at 48 kHz for a 30 second clip would add around 5 MB to the file size. Along with space to store such heavy files, you also need power to process them; this implies having a processor that runs at gigahertz speeds. CD drives and hard disk drives are simply not fast enough to access so much data and render it without any lags or jerks.

If you are using Windows Movie Maker to edit your videos, then save the file in the "DV-AVI [NTSC)" format. This ensures that the quality of the video remains as close to the original as possible. There is little loss in the video quality, but this depends on the quality of the video when captured.

If the capture quality is bad, then converting the video to the DV-AVI format won't make a difference. Unfortunately, high-quality audio-video files are anything but compact once converted into the DV-AVI format. Make sure you have plenty of space when using this format.
