Speed change doesn't work for Prores encoding

[Selur]

That's a bug, I usually use either Vapoursynth or Avisynth not ffmpegs filter for speed changes.
=> will look into it. (probably tomorrow evening)

Does this only happen if you only use video, without audio, or also when using video&audio? (I suspect it's a bug in the 'video only' handling when ffmpeg is the encoder.
