Ah yes of course, I had the numbers mixed up in my head. Thanks Nick.
Now when I do the conversion, I get all these non-monotonous DTS
warnings. Is there any solution to that, other than reducing the
loglevel? The output file seems to be correct, albeit without a
timecode track. Timecode is not imperative after this kind of
conversion, but I do think it would be preferable to stamp the first
frame the same as the source.
