https://bugs.kde.org/show_bug.cgi?id=430193 --- Comment #10 from Jason Straight --- This is still an issue. I rendered today and saw real_time is hard limited to -4, even if I try to set it in the other options widget. My encoding times are severely hampered because of this and my GPU (nvidia) is only being about 25% utilized for video encoding. Several times slower than ffmpeg or handbrake at encoding with similar options. -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=430193 --- Comment #6 from Jason Straight --- Maybe having it as a slider, separate from encoder threads, a processing (or rendering threads) and let people use what works okay for them. I haven't extensively tested it, but I've rendered several videos that had blurs, composites, transforms, rotoscopes, transitions, etc, and so far not had issues with the effects I've used. -- You are receiving this mail because: You are watching all bug changes.

Yeah. I should have elaborated. I'm using GPU for encoding. Nvenc. Increasing the processing threads from 4 to 12 really sped up my render times for final rendering and timeline preview. -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=430193 Vincent PINON changed: What|Removed |Added CC||vpi...@kde.org Status|REPORTED|NEEDSINFO Resolution|--- |NOT A BUG --- Comment #2 from Vincent PINON --- There is a misunderstanding: real_time is for *processing* threads (MLT calculating frames/slices in parallel) while encodethreads is for *encoding* (typically libx264 or libvpx compressing the calculated video). Increasing encodethreads works, but beyond 4 it doesn't speed up much. But MLT parallel processing doesn't always work well (with several frei0r effects/transitions). It is difficult to find a balance filling the cores for render, as either processing or encoding can be bottleneck depending on video characteristics... For previews, the codec used doesn't use frame-to-frame compression (MJPEG, DNxHD...), so encoding almost does not come into equation. -- You are receiving this mail because: You are watching all bug changes.
