Go ahead and fill us with bitmaps. They're valuable and text is so boring. It's way easier for us than downloading from some links. Lots of storage here, don't worry.

Bravo, thanks for the testing. That last BMP looks blown out. Is that HDR->SDR? How does the SDR one look?

It is hdr to sdr
I will try to find the same frame in the sdr version

This should be the sdr frame

Yeah, that's what I concerned about. What white level? Can you upload that section to my ftp?

My test on Interstellar(2014) UHD vs 1080p BluRay
Should add some tonemap via Madvr or whatever. Just need more time.
Now the DGTonemap looks too bright ( Sorry I am not familiar with algorithm so can only judge and comment by the versus comparisons without much analysis)
UHD Tonemapped and resized to 1080p vs
1080p BluRay

My script on UHD(tonemap)
Code: Select all
LoadPlugin("D:\dgdecnv2053\DGDecodeNV.dll")
LoadPlugin("D:\DGTonemap\DGTonemap.dll")
LoadPlugin("D:\avsresize\Release\avsresize.dll")
SetFilterMTMode("z_ConvertFormat", MT_MULTI_INSTANCE) # May not be needed.
DGSource("D:\Encode Folder\Interstellar\UHD.dgi",fulldepth=true)
z_ConvertFormat(pixel_type="RGBPS",colorspace_op="2020ncl:st2084:2020:l=>rgb:linear:2020:l", dither_type="none")
dgtonemap(white=100) # yes just want it not to be too bright so I set it so high
z_ConvertFormat(pixel_type="YV12",colorspace_op="rgb:linear:2020:l=>709:709:709:l",dither_type="ordered")
prefetch(2)
Spline36Resize(1920,1080, src_left=0, src_top=0, src_width=0, src_height=0)
1080p BluRay
Code: Select all
LoadPlugin("D:\dgdecnv2053\DGDecodeNV.dll")
DGSource("D:\Encode Folder\Interstellar\1080p.dgi")
They handle UHD in different way so it's zoom in a little bit (I am 100% sure UHD and HD are the same frame)? but it doesn't matter and tonemapped one does look too bright I guess. And in some scenes (I didn't post them) details in bright area are washed out.
Edit: one more vs when I use white = 0.7 :
100 vs 1080p BD vs 0.7
(Lastly plz forgive my poor english)

BTW, is "debug=True" in DGSource removed?

I think it's "show=true" is what you're looking for.

Just wondering, since the current version of DGTonemap aims at Avisynth+, do you plan to create a version for Avisynth 2.6 too?

2.6 one requires stacked or interleaved hack to work with HBD video. Not sure if avsresize support it.

Probably not, but the resizers in the dither package might work instead,..

Thanks, very much. Will work on improving the whites today.
Thanks to Nginx too for the test results.

@gonca
I see you are linking from the web for your images. Are you able to attach them to your post instead? Then they would be here permanently. If it is not working I can fix it.

Testing image attachment. Seems to work. Go to the attachments tab, upload image, and hit place inline. It seems that an extra blank line is needed to put a space between text and the image. I set the board quota to infinite and no limit on image size. You'll have to enable display of images inline in your user board prefs.

OK, boys and girls, please re-download to get DGTonemap 1.1. It should significantly improve the whites and be much closer to the SDR versions. You can tweak it further if desired using the contrast and bright parameters.

I'm disinclined to support the 2.6 HBD hack. I think that as we move into the UHD era we need proper HBD support in our frame servers and filters.
Do you have some reason to cling to Avisynth 2.6?

More a legacy thing. Got support for it in Hybrid and try to keep it alive.
I personally only use Vapoursynth nowadays since it's also available on Linux an Mac. (I only go back to Avisynth when I need some filters which are not available for Vapoursynth.)
So, no pain if you say you switched to Avisynth+, just thought I ask.
