A Helpful Tidbit That You Will Probably Not Enjoy
I'm posting this here not because I expect you to find it fascinating, but because I couldn't find these instructions online anywhere and had to figure it out for myself. So, here you go, internet. My gift to you: instructions for converting a multiplexed MPEG-1 to a more usable Quicktime format.
The problem: the MPEG won't play in a browser (you get a Quicktime-Q with a question mark over it), and when you try to export it from Quicktime player in MOV format, it won't acknowledge that there's an audio track. When you hit apple-I on the movie, you see that the audio track is "muxed," which means multiplexed. The audio and video are blended together in a delicious melange. You can fix that with a free program called Streamclip, and Quicktime Player, and iMovie.
- Open the MPEG in Streamclip
- Demux to an AIFF
- Open the AIFF in Quicktime Player
- Export the AIFF to MOV
- Import the audio-MOV into iMovie
- Import the original MPEG into iMovie
- Lay down the audio-MOV as the audio track, and the original MPEG as the video track
- Export the project as an MOV
Ta da. Enjoy your demuxed clips, internets.
