Hybrid: Input -> x264/x265/Xvid/VP8/VP9

[bob88]

Are the currently integrated vapoursynth filters 64bit?

[Selur]

Yes, Hybrid only supports 64bit Vapoursynth.

[bob88]

I just did a few tests with Vapoursynth's degrainers. Compared to Avisynth's 32bit Mdegrain I got the same speeds and the results qualitywise were less satisfying.

[Selur]

So your best bet is either not use Hybrid or find an alternative to MDegrain which runs under Vapoursynth that I could support in Hybrid, since I don't plan to support Avisynth 64bit. (or stick with the 32bit Avisynth version)

[bob88]

how about this SMDegrain?
https://forum.doom9.org/showthread.php?t=166582

[Selur]

Already comes with Hybrid, but isn't used other than in QTGMC atm. .
Looking just at the parameter list:

SMDegrain(input, tr=2, thSAD=300, thSADC=None, RefineMotion=False, contrasharp=None, CClip=None, interlaced=False, tff=None, plane=4, Globals=0, pel=None, subpixel=2, prefilter=-1, mfilter=None, blksize=None, overlap=None, search=4, truemotion=None, MVglobal=None, dct=0, limit=255, limitc=None, thSCD1=None, thSCD2=130, chroma=True, hpad=None, vpad=None, Str=1., Amp=0.0625)

Adding support for it will take me a while. (lot of tooltips&documentation)
-> will look into it, hopefully I get it done during the next week

[bob88]

ok Im super noob so I dont know what QTGMC is but Ill be waiting with anticipation for your update.
Thank you!

Sorry to repeat, Could anybody suggest something?

[Selur]

@alter4: You could use 'Crop/Resize->Misc->Misc->Rotate output' to rotate the video.

Hey Selur

I've been experimenting with nvenc hevc encoding and I always keep getting crashes

Could you check the log, please?

I suppose Im doing something wrong here..I dunno

Thank you

Vapoursynth script looks fine to me:

Encoding call seems fine too:

"F:\Hybrid\Vapoursynth\vspipe.exe" "F:\CORBEAU\encodingTempSynthSkript_15_34_40_3010.vpy" - --y4m  | "F:\Hybrid\ffmpeg.exe" -y -threads 8 -f yuv4mpegpipe -i - -an -sn  -vsync 0 -strict -1 -pix_fmt yuv420p10le  -vcodec hevc_nvenc -preset 5 -profile:v 1 -level 0 -rc constqp -cq 18 -2pass 0 -rc-lookahead -1 -surfaces 32 -nonref_p 1 -strict_gop 1 "F:\CORBEAU\test_15_34_40_3010_02.mkv"

(assuming your graphic card support 10bit hevc encoding; mine doesn't)

Cu Selur
What happens if you call the encoding call inside a Windows Command Prompt?

[Vesdaris]

OK.. I changed hevc to nvenc (not nvenc ffmpeg) and it works now.

I was wondering what settings would you recommend using for maximum quality? I mean these ones;

- adaptive quantization (enable it?) Strength can't be set though

- number of ref frames. 3 is default. Would 5 be a better choice quality\compression wise?

- It seems I can't enable B-frames..Is it supposed to be like this on nvenc-hevc?

-gop size max? default 0

- lookahead? default 16

Thank you!

[Selur]

adaptive quantization (enable it?) Strength can't be set though

Strength for adaptive quantizer is only available for H264. Yes, I would enable it.

Would 5 be a better choice quality\compression wise?

yes

It seems I can't enable B-frames..Is it supposed to be like this on nvenc-hevc?

Yes. The VPU doesn't support B-frames which is one of the main drawbacks.

gop size max? default 0

Quality/Compression ratio wise 0 is the best, for playback ease I would recommend something like 10 or 20 times the fps.

lookahead? default 16

Higher lookahead should provide better compression/quality, but will also require more gpu ram.

• Started Hybrid
• Set 'Best->Processing->Video' to 'x265'
• Selected 'x265->Base->Preset and Tune->Preset' to 'slow' and applied it. Resulting command line was:
  

  x265 --preset slow --input - --output-depth 10 --y4m --profile main10 --high-tier --level-idc 4.1 --qpstep 1 --crf 18.00 --qpfile GENERATED_QP_FILE --vbv-maxrate 50000 --vbv-bufsize 50000 --range limited --colormatrix bt709 --output OUTPUTFILE

• enabled 'x265->Quantization->QuadTree->cu lossless' command line changed to:
  

  x265 --preset slow --input - --output-depth 10 --y4m --profile main10 --high-tier --level-idc 4.1 --qpstep 1 --crf 18.00 --qpfile GENERATED_QP_FILE --cu-lossless --vbv-maxrate 50000 --vbv-bufsize 50000 --range limited --colormatrix bt709 --output OUTPUTFILE

• disabled 'x265->Quantization->QuadTree->cu lossless' command line changed to:
  

  x265 --preset slow --input - --output-depth 10 --y4m --profile main10 --high-tier --level-idc 4.1 --qpstep 1 --crf 18.00 --qpfile GENERATED_QP_FILE --vbv-maxrate 50000 --vbv-bufsize 50000 --range limited --colormatrix bt709 --output OUTPUTFILE

-> Can't reproduce the issue like I understood your description of the problem.

Ah okay, got it. Was a small bug, fixed locally.
cu-lossless should be disabled while cu-tree is disabled and not the other way around, will send you a link for a dev version which fixes this.

Please add information about the frame type (I-P-B) for Vapoursynth

[Selur]

@Graviator:Will think about it.

Hi selur,
I'm using Hybrid v2017.10.05.1, Linux 64bit qt521
When I load a BluRay and select a mpls play list, and Hybrid is analysing streams, Hybrid crashes. I reproduce the problem with several BD.
It does not happen in this same BD with Hybrid v2017.05,06.1

I send you a debug file.
