[RESOLVED] Indexing Issue
Hi, I've been running into an issue lately. There are glitches in a few frames when indexing with DGDecNV (latest version) although the file appears to be normal during playback in MPC/VLC. I took 2 screenshots of the same frame, taken with MPC and DGDecNV (also, "show=true" in x64 doesn't seem to w...

Re: HDR -> SDR tonemapping
In the manual of the version 1.4 says that the "gamma" parameter has a default value of 1.42. Could this be a typo?

Re: HDR -> SDR tonemapping
I've got this weird green thing when using Hable in the latest DGHDRtoSDR_1.2.
Gamma mode:
My code for Hable mode:

Re: HDR -> SDR tonemapping
Thank you so much for your work.
From my initial tests, I've experienced some heavy banding with the "equal" value being anything other than 0.

Re: HDR -> SDR tonemapping
I have a question. In the DGTonemap's manual, the formula for Hable is
Can you tell me what the "x" variable means? Thank you.
Code: Select all
hable(x) = ((x*(a*x+c*b)+d*e) / (x*(a*x+b)+d*f)) - e/f

Re: HDR -> SDR tonemapping
I feel like without an HDR monitor as a reference, every setting would be a guess-timate. Trying to pick the right setting is quite a challenge.

Re: HDR -> SDR tonemapping
I mess around the "bright" parameter, but cannot see any difference between the values (default, 1.0, 5.0). Not sure where I did wrong. Here's my script: DGSource("br2049.dgi", crop_t=280, crop_b=280, fulldepth=true).Spline36Resize(1920, 800) z_ConvertFormat(pixel_type="RGBPS", colorspace_op="2020nc...

Re: HDR -> SDR tonemapping for DGDecodeNV
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. Thank you for the update. Could you please tell me the default values of "con...
