Summary of the bug:
I am trying to rewrap a DV in a QuickTime container but getting an error
"fps 60000 is too large" (preceded by a log message "Using non-standard
frame rate 60000/1"). The files appear to be 30000/1001 in a few tools I
checked (QuickTime, VLC, MediaInfo, AtomBox). The files transcode without
issue in FFMPEG 6.0.1 but not in 6.1. The issue persist in the latest
build I tested (N-118022-gca889b1328-tessus).
How to reproduce:

The sources are dv files I used FFMPEG to capture via Firewire. I also
used FFMPEG to create dv files from other sources, but those have the same
issue in modern (>6.0.1) versions.
