Explanation:
Detailed explanation-1: -AVI format is uncompressed, which means that AVI video requires more hard disk space. For example, one hour of AVI video data in 352x288 resolution will occupy up to 33GB (3300 MB) hard disk space. Uncompressed video has the highest quality, and DV camcorders use DV-AVI as their storage format.
Detailed explanation-2: -"Full-resolution” video is typically captured at 640 x 480 resolution, 640 pixel dots across by 480 lines of pixels down. Just one frame is 900 KB of data, or almost enough to fill one floppy disk. Video clips designed to be played on a PC are typically stored at half resolution, or 320 x 240.
