LUT CALIBRATION

[Devilouned]

Hello I get this error when I try to make LUT calibration on HyperHDR. Both using test video or web browser.
I use PicCap on my rooted LG TV WebOS.
I must be missing something..
Any help ?

Hi
You are using an older Piccap that either does not support NV12 or you have not enabled it. See this guide: https://github.com/satgit62/Ultimate-HyperHDR-Ambilight-fine-tuning-experience-for-LG-webOS-with-new-LUT-calibration-

Thx for your rapid answer.
I use the latest version of Piccap & I edited the config.json
Will try again tomorrow.
Best regards.

it's possible that the changes weren't included in Piccap which is available for download in their repo. Not my decision, I don't manage it, besides distributing HyperHDR with only one LUT table defeats the purpose (there's no SDR on webOS, each SDR/HDR mode requires its own LUT), maybe because they focus more on Hyperion than on HyperHDR despite the fact that we offer much more possibilities here.

Mb you could tell me where I can download the required version ?

I don't follow what's happening on webos for the reasons I wrote above. It seems to me that the best option for you will be to follow very detailed instructions prepared by our colleague @satgit62
