Stuttering in FFMPEG output video
on Jun 27, 2017 at 6:36:01 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=3840x2160 -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?
