Comment (by rogerdpack):

 Seems to work ok if using -vf fps.  Only -r 27 (like ffmpeg.exe -f lavfi
 -i testsrc=duration=30:rate=1  -r 27 out.mp4) seems to fail for me.

 Also saw this note on #3164 "Note that the pullup filter does not work
 correctly with the fps filter, it currently needs -r." Thanks!
