Re: NVENC versus CUDA and Hardware Encoding Performance

At least on windows, the encode utilisation is under a separate graph as well and it makes sense given it's discrete hardware. Yeah, I miss my little Task Manager GPU charts (but not enough to abandon ship on Linux). I'd wager any "GPU" utilisation is orchestration, memory bandwidth, PCI-E link ban...

Thank you for the clarification; I'll make sure to output the logs with each encode for reference.

Re: 'More Settings' Field Disappears When Using Hardware Encoders

Each Platform has it's own dedicated UI. The linux is a GTK ui and the code is on GitHub. It's probably not a particularly complex change. Might be a perfect opportunity for me to use my limited programming skills and dip my toes. :) I'd also like to contribute to the documentation in a similar man...

Re: 'More Settings' Field Disappears When Using Hardware Encoders

It's been raised a number of times in the last year or two. It's actually not a bug but just not implemented due to a lack of developer interest / time. Patches are defiantly welcome In the spirit of defiance , I'd love to help in any way I can. I'm surprised the Linux port would have a difference....

Re: NVENC versus CUDA and Hardware Encoding Performance

It's still a bit confusing for end users because NVIDIA's API for NVENC does use CUDA (even though the encoding is still done on the dedicated hardware rather than the GPU itself). To add to this confusion, the NVIDIA X Server Settings panel (Linux) has a GPU Utilization (percentage) and a Video En...

Re: NVENC versus CUDA and Hardware Encoding Performance

Your choice of a 1650 is a good one, according to at least two engineers I know. My friends at the PLEX forums recommended this when I broached the subject of a low-cost, purpose-built encoding "appliance." I'm tickled that it doesn't matter which Turing GPU you buy as they all have the same NVENC ...

Re: NVENC versus CUDA and Hardware Encoding Performance

NVDEC/ENC is on the main GPU ASIC, not a separate ASIC. The ASIC is integrated into the GPU, but it is discrete from the CUDA Cores. These seems supported by the available NVIDIA documentation. https://developer.nvidia.com/blog/wp-content/uploads/2019/07/image5-1024x600.png The NVENC documentation ...

Re: NVENC versus CUDA and Hardware Encoding Performance

I really appreciate the veteran user response; Thanks for taking the time. I don't think there's much to debate on whether software encoding will provide a better encode (a la "archival quality"). In my workflow, I'm working with commercial discs. If I wanted to truly "archive," I'd stick with the o...

Thanks for the confirmation. I hadn't loaded Windows to check, but I'll take your word for it.

Do I need to submit some type of bug report, or have I effectively done it with this post?

The text field should be available nonetheless. Agreed; This is the first version that I've seen where the More Settings field disappear when selecting a Hardware Encoder. I don't know if this is something with the Linux port, the version (1.3.3 x86_64), or what. Seems like a bug rather than a feat...

'More Settings' Field Disappears When Using Hardware Encoders

I'm running Ubnuntu 20.04 with HandBrake v1.3.3. It seems that selecting the Nvidia NVENC H.264 and HVEC hardware encoders will make the More Settings field disappear. Is this a known issue?

Bradley, Those references are a fantastic deep-dive into the encoder settings. Thank you very much for posting those links! You're right; some of the x264 table data is dated, but it's nice to see it laid out. Perhaps that type of table is something we could maintain in the HandBrake documentation? ...

Another test with a 6-channel DTS-HD MA audio stream reveals a similar effect after Handbrake encode.

Re: DTS-HD MA 8 Channel (7.1) Audio Passthrough - Possible?

Also, the DTS core substream is always a downmix of the full 7.1 track; the official DTS encoder knows better than to drop 2 channels to the floor… That's a great tidbit of information, and it's indicative of how DTS handles the core substream processing. That helps my workflow tremendously. Thank ...
