Re: processor core count

Depends on which video encoder, filters, settings you use, and also what format your source video is in, etc.

Re: HandbrakeCLI on Ubuntu with Python Errors

On POSIX, if args is a string, the string is interpreted as the name or path of the program to execute. However, this can only be done if not passing arguments to the program. Note: It may not be obvious how to break a shell command into a sequence of arguments, especially in complex cases. shlex.s...

Re: 60fps H265 video stuttering on Roku Streaming Stick+

IIRC libx265 doesn't let us flag bitstreams as VFR like we do for same as source with libx264; we just set the framerate to that of the source without accounting for any filters, which is not ideal. Not sure how we could best work around it though.

Do the HandBrake encodes stutter locally in e.g. VLC as well?

Nope, "min-keyint=1:keyint=1" should do the trick though.

When remuxing with MKVtoolnix, does demuxing first to an elementary stream and then muxing from that help at all?

Re: Handbrake crashes while using Libmmbd from Makemkv

Probably a side-effect of application sandboxing.

It might be possible to avoid the crash. I wonder if one can build libbluray with flags to disable libaacs and libbdplus support (which is what libmmbd emulates)?

That's already a lot, most of the encoding is actually done on a dedicated video encoding hardware chip that just happens to be on the GPU.

or only H.265 (x265) ?
Both are HEVC encoders; x265 will definitely work at 5400x2700; not sure about the NVIDIA-accelerated one but it's easy for you to try to since you apparently have the hardware for it.

You cannot change frame rate of a video without re-encoding (unless you're trying to make it slow-motion)?

That's a bit weird, do you have short samples (30 seconds or less) you can upload somewhere (same source, with a DNxHR vs. the other intermediate codec)?

Re: How can I get the real time in activity log

HandBrake's internal timebase is 90 kHz, that's 90,000 ticks per second. PTS 219497407 is 219497407 / 90000 ~= 2438 seconds i.e. 40 minutes, 38 seconds.

Re: MKV file plays properly in VLC before Handbrake, but high CPU and not responding in VLC afterwards

After trying to encode it either via VidCoder or using Handbrake (different qualities and settings) it causes VLC to choke and report Not Responding when I try to change audio tracks Can you try the following?

Re: MKV file plays properly in VLC before Handbrake, but high CPU and not responding in VLC afterwards

If you really want to change the encode to try to make it work in VLC, try the fastdecode tune. That may only work around whatever the issue is, on that CPU, even with avcodec's software decoder, there's no way VLC is struggling to decode this file. Could be I/O but even that sounds unlikely.

Re: Help with x264 enccoding for Bl-ray authoring

Well, some authoring software will ingest raw H.264 from x264 without re-encoding if you use the settings outlined there: http://www.x264bluray.com

A raw bitstream is required though, so it rules out HandBrake.

Re: Converting 4K SDR to HDR video

Cannot be done. You can do HDR to SDR (not necessarily with HandBrake), but you cannot add color information that isn't there in the first place (SDR -> HDR), with any software.
