Hybrid(Windows/Linux/Mac): Input -> x264/x265/Xvid/VP8/VP9

[Selur]

When I reencode the content the output passing through the HDR and VUI data as in call above, the reencode is properly displayed as HDR using MPC-HC ('passhtrough HDR to display' in madVR). This is probably the cause, why I didn't notice the difference.
Still transfer should be signaled too, which causing the difference in MediaInfos output.

It is btw. also on other sources from (for example) a natural documentary in 4k hdr. Same behaviour

This will happen with everything you encode with NVEnc to HDR.

Ok, when you say it happens always with Nvenc, i testet it also with x265 and it does happen too there.

When i use this setting:

x265 --input - --fps 24000/1001 --output-depth 10 --y4m --profile main10 --limit-modes --no-early-skip --no-open-gop --opt-ref-list-length-pps --lookahead-slices 0 --crf 18.00 --opt-qp-pps --cbqpoffs -2 --crqpoffs -2 --qpfile GENERATED_QP_FILE --limit-refs 0 --ssim-rd --psy-rd 2.50 --rdoq-level 2 --psy-rdoq 10.00 --aq-mode 0 --deblock=-1:-1 --limit-sao --range limited --colormatrix bt2020nc --master-display "G(13250,34500)B(7500,3000)R(34000,16000)WP(15635,16450)L(10000000,1)" --hdr10 --sar 1:1 --output "C:\Users\Gaming-Tower\AppData\Local\Temp\König-Der-Löwen_25sec_new_new.265"

and also, when i use this setting:

x265 --input - --fps 24000/1001 --output-depth 10 --y4m --profile main10 --limit-modes --no-early-skip --no-open-gop --opt-ref-list-length-pps --lookahead-slices 0 --crf 18.00 --opt-qp-pps --cbqpoffs -2 --crqpoffs -2 --qpfile GENERATED_QP_FILE --limit-refs 0 --ssim-rd --psy-rd 2.50 --rdoq-level 2 --psy-rdoq 10.00 --aq-mode 0 --deblock=-1:-1 --limit-sao --range limited --transfer smpte2084 --colormatrix bt2020nc --master-display "G(13250,34500)B(7500,3000)R(34000,16000)WP(15635,16450)L(10000000,1)" --hdr10 --sar 1:1 --output "C:\Users\Gaming-Tower\AppData\Local\Temp\König-Der-Löwen_25sec_new_new.265"

So the "hdr10 compatible" dissappear on medinfo and it is not displayed correct anymore on my end.

have all have to be set

Ahh thanks, now it works. But it works with NVEnc too now:

[Selur]

yes, I know.

[Platos]

I know it's quite early, but do you plan to implement h.266 (VVC) decoding encoding ?

If yes, maybe this helps you: https://github.com/MartinEesmaa/VVCEasy/blob/master/FFMPEGVVC.md

If not, maybe it's just interesting for personal use or so

[Selur]

Last I checked, libav and ffmpeg both didn't support H.266 and there was no support to mux using mkvmerge or main-tree ffmpeg.
-> once it can be decoded in Avisynth/Vapoursynth and muxed into a container I will look at it.

[Platos]

Ah ok, yes i forget about muxing.

Other question: On RIFE Scene Detection you write "In order to avoid artifacts at scene change, invoke `misc.SCDetect` on YUV or Gray format of the input beforehand so as to set frame properties."

Does that means, i have to use "misc-SCDetect" otherwise scene detection won't work properly? Where can i find this setting?

[Selur]

Hybrid will add SCDetect if 'Scene change' is enabled, but depending on your source, you might want to look at some scene changes and adjust the threshold configured there. (you can check in the Vapoursynth Script view)
The default 0.15 is a good starting point, but might be too low for some HD and too high for some SD content.

Cu Selur

[Platos]

Ahh, i did not know that higher resolution needs lower values.

Yeah i use now 0.1 for a 4k video because 0.15 was to high. Normally 0.15 did work most of time, but most of time i have 1080p content for interpolation.

[Selur]

Always depends on the content.

[peg]

I have a large collection of uncompressed YUV 422 720x486 video. I would like to keep it uncompressed for interchange between various editing software I use.

Is there any way to get Hybrid to write uncompressed video files?

[Compositor]

Is it really necessary for the Hybrid installer to be over 1GB in size?

[Selur]

Is there any way to get Hybrid to write uncompressed video files?

No. Hybrid does not support raw yuv (or y4m or rgb) as output.

Is it really necessary for the Hybrid installer to be over 1GB in size?

With the stuff it includes: Yes
Just the RIFE dependencies are 1GB (extracted) in size.
Unless I would not include either Avisynth or Vapoursynth support, the file size is at it is.
The only way I can think of would be to additionally use executable compressors like UPX.
I did that a bunch of years ago, but then had tons of folks complaining that they frequently get false-positives from their anti-virus scanners. Additionally tons of testing has to be done since those compressors do not work well with all dll and exe files.

Thanks for the confirmation on uncompressed files. I was afraid that was the case.
I know Hybrid writes several different lossless formats, and I am experimenting with them. I would need the other programs that I am using to both read, and export lossless to make two way file transfers possible without an additional re-code step. I will follow up when I have more results in.
