They may recompress the video to another format in a process called transcoding, or may simply change the container format without changing the video format. The disadvantages of transcoding are that there is quality loss when transcoding between lossy compression formats, and that the process is highly CPU -intensive.
In contrast to that, some very general-purpose container types like AVI (.avi) and QuickTime (.mov) can contain video and audio in almost any format, and have file extensions named after the container type, making it very hard for the end user to use the file extension to derive which codec or program to use to play the files.
An AVI file may carry audio and visual data inside the chunks in virtually any compression scheme, including Full Frame (Uncompressed), Indeo, run-length encoding, and Microsoft Video 1. [ 10 ] Some programs, like VLC , complain when the "idx1" index sub-chunk is not found, as it is required for efficient moving among timestamps.

M-JPEG is an intraframe-only compression scheme (compared with the more computationally intensive technique of interframe prediction).Whereas modern interframe video formats, such as MPEG1, MPEG2 and H.264/MPEG-4 AVC, achieve real-world compression ratios of 1:50 or better, M-JPEG's lack of interframe prediction limits its efficiency to 1:20 or lower, depending on the tolerance to spatial ...
