.avi and .mov rewrapping

[SCDVD]

I am making a presentation to a group of videographers about codecs as well as file handling when editing video. One of the topics will be the importance of rewrapping rather than reencoding when there is a need to convert to or from an .avi or .mov file. Some people load the video into their editor and render it to the desired file type. This unnecessarily damages the video because of the reencoding introduces compression artifacts.

I want to recommend some good video file rewrapping tools that don't reencode. I would appreciate suggestions for these for both PC's and Mac's.

Re-encoding is damaging only if you use lossy compression. Lossless compression or uncompressed is another option that is non destructive

It depends on the codec being used, because not all are compatible in every container. e.g. lagarith won't work in mov container, but works fine in avi container.

Some PC re-wrapping tools : mp4box (yamb is a gui for it) , mp4muxer, mkvmerge, avidemux (in copy mode), tsmuxer

ffmpeg (command line tool but very versatile like a swiss army knife, crossplatform linux/PC/MAC)
