What I mean by out of sync is, when I looked at the extracted audio and the
video in Premiere, they were out of sync with one another. Note: I had to
convert the mkv into an mxf to open it in Premiere. The mxf was shorter
than the mkv and the audio clip, but when I snapped its end to the end of
the audio, the audio and video were back in sync.
