LUT for UGREEN 25173

[ojnde]

Hi!
For whatever reason I fail to calibrate LUT: during the process everything gets a cyanish tint and the pattern is not recognized. Could someone share his calibration for this grabber?

Hi
Use P010 format for capturing. I own this grabber, use it on daily basis and its phenomenal (other modes than P010 are so-so): #967 (comment) I wont provide dedicated LUTs anymore after what happened with ms2130 (diffent firmwares) and Elgato (different HD60x hardware revisions)

during the process everything gets a cyanish tint

that's normal and the screenshot in the wiki shows it as an example also: https://github.com/awawa-dev/HyperHDR/wiki/lut-calibration

[ojnde]

I have seen the screenshot but my calibration trials never capture any testboard, only "waiting for"...

[awawa-dev]

make sure the CRC boxes are visible: first and the last line on the example screenshot. Other possible explanation: your movie player changes video aspect ratio or crops it.

[ojnde]

The player ist VLC on FireTV Cube and the video seems ok when captured. Still, the pattern is not recognized. Strange enough...
There is some signal processing following the FireTV including HDR to SDR conversion using HDFury DIVA so that the grabber input is 1080p SDR but this is the signal chain that works for HyperHDR itself. Only LUT calibration fails.

[awawa-dev]

it's hard to speculate on something abstract without full logs from the calibration attempt or a high resolution screenshot of the video preview. VLC is OK, but it all depends on the settings used and HDFury DIVA could introduce additional factor. Since Diva has applied its own tone mapping and the signal is some kind of their kind of interpretation how HDR should look in SDR you should stick to it. Tone mapping after another tone mapping has not been tested and the result can not be predicted. Although test boards should be detected unless some heavy dithering has been applied causing heavy noise. But this you should find in logs.

[ojnde]

Whatever I try - and I tried a lot - I cannot find a hardware setup or software settings that allow for a pattern recognition when the calibration videos are played by the FireTV Cube. Black in the patterns is far from pure black on the screen and this makes the calibration fail.
DIVA included or not does not make any difference. I enjoy HyperHDR a lot and would love to have a full calibration.

[awawa-dev]

Black in the patterns is far from pure black on the screen

that not true, it's not the reason for the board is not detected

[ojnde]

The log shows resolution too low or to much noise. Visually, the playback of the calibration video does not show pure black. Of course, it is pure black in the file itself. I thought this was the reason for the calibration to fail, but I might be wrong.

[awawa-dev]

I'm sorry I can't help here, I asked you for some things earlier. btw what you see in the preview during calibration is raw YUV that's why you won't receive true black color there. Anyway I hope you will find your own way to resolve it.

[ojnde]

You may be right and I was checking the wrong places...
