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

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. Does ...

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.

Re: Help With Handbrake Settings For Good Quality Output

Auto Passthru is just a multi-codec passthru with checkboxes; provided the DTS-HD checkbox is ticked and the source track is DTS-HD, then Auto Passthru and DTS-HD Passthru will behave exactly the same.

Re: Mediainfo doesn't give Audio and Video bitrate + subtitles

Per-track bitrate is custom metadata created by mkvmerge. HandBrake doesn't create it, but you can always remux its output with mkvmerge (via e.g. MKVToolnix GUI) to get them.
