Re: High core counts and video quality

If it's the only thing taxing the CPU and there are at least 8 physical cores, then no, it is not a detriment to an 8 thread workload whether the CPU is exposing 8 or 16 logical cores.

Re: High core counts and video quality

That's not really how hyperthreading works. 8c/16t isn't processes running on half cores compared to 8c/8t. Even so, x264 uses an appropriate number of threads. 1.4x logical cores IIRC.

Re: Help with tuning encoder for 480p anime

Sometimes, yes. We've tried to make presets forward compatible in that we have code to upgrade older presets, but can't guarantee it 100%. And cross-platform has some quirks.

Glad to hear you got it mostly solved. :)

Re: Help with tuning encoder for 480p anime

Not sure how you ended up with x265 options for the x264 encoder.

Try using the Decomb deinterlacing filter set to EEDI2. It's slower but slightly better quality for difficult sources.

Re: Export statement wrong in 1.3.3 build scripts?

If you have time, will you please check whether this is still an issue with the latest version of the build script? https://github.com/bradleysepos/mingw-w64-build

I maintain this separately from HandBrake and it is slightly older on the 1.3.x branch. Thanks.

Re: x265 8 vs. x265 10 Banding & Noise Comparison

The gist of it is x264 and x265 have perceptual optimizations that subjectively produce better quality for the human eye, but penalize psnr/ssim (because they are imperfect). Thus to do a fair psnr/ssim comparison, the associated tune(s) are recommended to avoid skewing the results for those particu...

Not exactly specifying the options correctly, either. option1=foo:option2=bar etc.

For a lecture you can probably use mono audio and half the audio bit rate.

Re: x265 8 vs. x265 10 Banding & Noise Comparison

So the x265 dithering algorithm(s) produce different results between 8- and 10-bit output, given an 8-bit input. That seems reasonable on its face, and given the way quantization error works the 8-bit result seems appropriate. Indeed, without settings to compare, it's certainly possible some additio...

Re: How to Override video levels transform AVI to x264/x265

Make sure your source video has its range info defined, and use HandBrake 1.3.3 (prior versions had a couple bugs leading to possible double range conversion).

For devices that do not support H.265, you can try x264's aq-mode 3, which biases to dark scenes: https://en.m.wikibooks.org/wiki/MeGUI/x264_Settings#aq-mode Add aq-mode=3 to the advanced options (x264 only). Helped me in a pinch once or twice. Using a 10-bit H.265 encoder is preferable if your devi...

Re: No valid source or titles found

Thanks for the Activity Log. HandBrake is certainly tripping over your file a bit. Try disabling Intel QSV decoding in HandBrake's preferences and let us know whether that helps.

Re: Covert MKV to MP4 and stay 4k

HandBrake's 4K presets (with the exception of the Playstation and YouTube ones) make H.265 video, which is slower to encode, but is what most 4K video players and devices expect. You can adjust the quality as you please, see https://handbrake.fr/docs/en/1.3.0/work ... ality.html

We do have code for "smart" frame dropping written by John, maybe it's selecting the wrong frames to drop in that case?

Ideally, HandBrake should drop every other frame in this case. I wonder whether something is causing that to not be the exact case.

Re: NOTICE: Read Me if HandBrake won't start

Perhaps the confusion comes from x64 also being used to denote 64-bit x86, usually on Microsoft platforms. Nevertheless, x86-64 is an appropriate designation.
