The documentation for the Aiptek PocketCinema pico-projector claims to support the following video formats:
- MJPEG AVI (recommended)
- MPEG-4 ASF
So how do I convert video into one of these formats on a Mac with QuickTime Pro?
Test: Use QuickTime Player to Export Movie to MPEG-4.
Result: FAIL. PocketCinema hangs when attempting to preview video and needs to be reset by removing battery.
Test: Use QuickTime Player to Export Movie to AVI. MJPEG is not support. Try uncompressed, BMP, and Cinepak.
Result: FAIL. PocketCinema recognizes AVI file, does not hang, but also does not play any of the files (uncompressed, BMP, or Cinepak).
Test: Use QuickTime Player to Export Movie to QuickTime Movie with Motion JPEG codec.
Result: FAIL. PocketCinema does not recognize .mov file.
Test: Use QuickTime Player to Export to MPEG-4, then use Flv Crunch to convert to MPEG-4 again.
Result: Success! Apparently the projector has a problem with the MPEG4 generated by QuickTime, but does not have a problem with the MPEG4 generated by ffmpeg.
Behind the scenes Flv Crunch is just using the ffmpeg command line tool. The following command did the trick for me:
ffmpeg -i source.mp4 dest.mp4
