That won't last forever (sorry couldn't resist)

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.

you mean H.265 (Nvidia HVEnc)
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.

Gotta be the former.

Your math seems possibly off here

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)?

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.

HandBrake's --main-feature is more reliable for DVD than it is for Blu-ray.

x264 is a command-line application. You can install it via e.g. Homebrew https://brew.sh

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?

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.

No idea, those articles were really meant to target professional authoring software.

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.

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.

Wasn't he trying to get a minimum bitrate of 1,000 (with no limitation on the maximum)? I must admit I didn't follow this thread very closely, only saw the request for a minimum bitrate.

Looks like I used it for Aliens and Jurassic Park (1080p, H.264 High Profile, level 4.0 -> VBV 31250/25000), RF 20 with a crf-max of 25.5… My BD discs of Aliens (and to a slightly lesser extent, the first JP movie) have a lot of very fine grain, I noticed in a previous encode that VBV was very activ...

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.

I’m not sure that would even work, it’s description says “It prevents x264 from reducing the ratefactor (aka "quality") below the given value even when doing so would violate VBV constraints.” If I set my CRF to 27 and my CRF-max to 20 wouldn’t that just give me a CRF 20 encode? Any vbv s...

Skipping subtitle scan.  No suitable subtitle tracks.

Foreign audio can only works if there are multiple subtitle tracks.

There are multiple subtitle tracks in his input. The issue here is, HandBrake's Foreign Audio Search only works on DVD and Blu-ray format subtitles.

To elaborate, here are the output audio tracks: [23:50:22] mux: track 1, 126377 frames, 288577256 bytes, 1712.55 kbps, fifo 4096 [23:50:22] mux: track 2, 63189 frames, 26985878 bytes, 160.15 kbps, fifo 2048 [01:38:58] mux: track 1, 126377 frames, 288577256 bytes, 1712.55 kbps, fifo 4096 [01:38:58] m...
