  Stuttering in FFMPEG output video

  Posted by Jillian Morrow on June 27, 2017 at 6:36 pm

  I’ve been trying to encode a video and with every result I end up with a slow, stuttering video. I’m limited to 30 FPS and 30 Mbits, but I figured the interpolation filter would solve the stuttering.

  Ex: ffmpeg -framerate 30 -i img%05d.png -filter “minterpolate=’mi-mode=mci:mc_mode-aobmc:vsbmc=1′” -vf scale=3840×2160 -c:v hevc_nvenc -b:v 30M -maxrate 30M -bufsize 60M Output.mp4

  However, every variation of the filter is still stuttering. Does anyone have any advice on how best to use this filter? Any alternatives?

  When I see your output specs, I can’t help but wonder if the stutter you are seeing is an encoding problem, or a playback problem.
  What sort of stutter are you experiencing?

  If there’s a stutter in the video / encoding process, it should be visible also if you skip through the video frame-by-frame in your NLE of choice. Is that the case? Because if so, we’re looking at a blending / interpolation problem.

  However, whta I’m thinking is that this might be a playback issue rather than an encoding problem.
  What hardware and software are you using to play this UHD HEVC video?
