Paul, I know you're a smart guy and can keep 'N' balls in the air at the same time.

How do *you* explain this:

'ffmpeg -i input.mkv -vf "settb=expr=1/360000,showinfo" -codec:a copy -codec:s copy -dn output.mkv'

[Parsed_showinfo_1 @ 00000211128f2340] n:   1 pts:  11880 pts_time:0.033 ...
[Parsed_showinfo_1 @ 00000211128f2340] n:   2 pts:  24120 pts_time:0.067 ...
[Parsed_showinfo_1 @ 00000211128f2340] n:   3 pts:  36000 pts_time:0.1   ...

Why aren't those numbers:

[Parsed_showinfo_1 @ 00000211128f2340] n:   1 pts:  12012 pts_time:0.033 ...
[Parsed_showinfo_1 @ 00000211128f2340] n:   2 pts:  24024 pts_time:0.067 ...
[Parsed_showinfo_1 @ 00000211128f2340] n:   3 pts:  36036 pts_time:0.1   ...
?

They're supposed to be '12012' '24024' '36036'.
