What you could do:
- Post full command line _and_ output of the ffmpeg command that
converts the AVI file to the image sequence (if your assumption is
correct, the output will probably show if ffmpeg knowingly duplicates
- Ensure the timestamps correspond to the assumed framerate by using
the setpts filter and see if that makes things better
- Check/post output of ffprobe for the frame timestamps to see if they
- Not complain about the time you lost using ffmpeg (here) because it
is nobody's fault
