I don't know of any low-cost tools to generate the RPU data from the stream. ColorFront Transkoder is an option but is very expensive.

Extra zoom ratio for 8K contents?

Tried to index a 8K file on a 1080p screen, and the main window broke the border of the screen.
Would be sweet to have an extra zoom ratio of 1/6 or 1/8 and be able to automatically switch to that for 8K content.

Thanks.

Along the same line
Would it be possible to add more zoom options or a sliding scale
My particular case use
I use 4K tv as monitor
My settings in Win 10 are to use 175% size
I can only use up to zoom 1/2 ( 0.5*1.75=0.875) of screen
If I select zoom=1 ( 1* 1.75 ) then the window is to big
Also consider zooming a 1080p video on a 4k monitor, zoom>1 would be nice to have

Bullwinkle has talked about the "handcuffs of zoom". Need to break the chains.

Maybe we can get Sherman on this...when he finishes his homework. :lol:

I've got Zoom = 1/8 implemented but need to get the PCM wrapping in there. Sherman, how is that coming along?

Code's done for DGIndexNV W64 wrapping. I updated the DGIndexNV user manual too.

Over to you, Rocky.

Thank you, Sherman. I'll make a release first thing in the morning.

As a reward, I'll ask Mr. Peabody to let you stay up an extra hour tonight.

I checked many HDR10 movies and everyone has "Chroma subsampling : 4:2:0 (Type 2)" in MediaInfo. Do you think X265_CL must contain one more option --chromaloc 2 ?

I don't know what X265_CL is, and it doesn't seem related to DG stuff.

DGDecNV slipstream 207:

* Added a line X265_CL to the bottom of the HEVC index file (for HDR PQ streams) containing command line
parameters for x265.exe derived from the colorimetry, HDR metadata, and frame count. This line
can be cut and pasted to your x265 invocation. :salute: Boulder

Ah yes, dementia setting in. I'll look into whether there is enough information in the input stream to definitively set this option.

Default undefined (not signaled)
https://x265.readthedocs.io/en/default/ ... -chromaloc
MediaInfo displays "Chroma subsampling : 4:2:0" in encoded movie, without Type 2 if chromaloc not set in x265.

Please re-download build 2053 and update DGIndexNV. I snuck this feature in for you. Thank you for the suggestion.

Thanks. It may help other people to create more correct 4k HDR videos

Would it be possible to have DGDecode output the native bitdepth of the source? My point is that for HDR sources, I could do the motion analysis in MVTools in 10-bit domain and then denoise in 16-bit domain for a nice little speedup. It doesn't make sense to dither down to 10 bits in this case as the final output will be 16 bits anyway.

No, I mean the output you get from DGSource. As far as I know, both Avisynth+ and Vapoursynth accept YUV420P10 happily.

You can use ConvertBits(). Is it so terrible?

NVDec gives me 16-bit output. You know that, right?

Actually I didn't know that 16-bit output is what the NVidia decoder gives you ;)
I'll test if there is any actual visible difference if I dither down to 10 bits and use that as an analysis clip. It won't be used for the actual final output so chances are that it's faster and not distinguishable at all.
