The settings I used (for ffmpeg 126.96.36.199 running on Mac OS X El Capitan via
ffmpeg -i A%04d.png -vcodec libx264 -pix_fmt yuv420p -r 60 A.mov
The clock values in POV are set for a 24-FPS film, but I have to set -r to 60 to
get rid of herky-jerky frames that hang every second of runtime. I'm sure
there's a long and convoluted technical reason for it, but I have no clue what
it is (and as long as -r 60 solves my problem, I don't care)...
