    2114It does output a mp4 file though but on files that are larger sizes (because the sample file is just a sample), it is taking a long time (like 5 minutes for a 5 minute video) and the result file is a lot larger than the other files I've converted.  I think it has something to do with the Q264 codec that was used to encode the videos originally.  I can encode other videos that were originally encoded using the QIVG codec with the above command and I get no error messages and a 5 minute video is encoded in under a minute.  I'd like the videos encoded in the Q264 codec to be re-encoded in under 1 minute just like the videos encoded in the QIVG codec if that is possible.
