ffmpeg -acodec copy -vcodec copy This will copy the audio and video streams (without recompression) and repackage into a new container. For instance, if you have an mp4 and want to copy the audio/video streams (and nothing else) into a new mp4: ffmpeg -acodec copy -vcodec copy -i input.mp4 output.mp4 There are other tools, but I don't know of anything easier than this. I haven't tested it specifically for this purpose (stripping metadata) but since metadata is stored at the container level - not within the a/v streams - it should work just fine. And it's fast since there's no compression going on. I regularly repack MKVs into MP4 for my AppleTV and it's only a little slower than just a straight file copy. -R
