Anti-Flickering settings are not working with v20 ?

@awawa-dev

Addon works with PI 5 and LE 12 - thank you very much!

As i wrote in previous posts, AntiFlickering Settings are not working any longer.

I made two videos with exact same settings.
The first one is HyperHDR 19, second one ist with HyperHDR 20. Same settings (imported via json)

Please have a look!

Anti Flickering settings (on both systems!)

[Johnny1982fd]

You mean increasing this value?

Details

If yes, biggest value 8 has no change. Flickering still exists. :(

[awawa-dev]

No, backlight threshold which corresponds to the minimal backlight in the processing tab (default was 2 in v19, now it's 1 in v20, may be related to effectiveness of anti-flickering filter in lowest range). You also have some not-default settings in the smoothing tab (continues output enabled, timeout = 0, who knows what's more elsewhere). I've just tested anti-flickering filter on my v20 and it definitely works fine.

These test-only settings can confirm it'w working and can be even visible:

If you play some video then if you pause it, some LEDs will be updated suddenly after 2 seconds (these LEDs were frozen to eliminate "flickering" for a such configuration and were updated after a timeout, 255 means it worked for all the color range). Not for every scene, but it's rather often case for darker scenes that were changing.

[awawa-dev]

didnt change LUT settings in V19 or 20.

that's not what I asked for

[awawa-dev]

Photos are not necessary but JSON backup maybe could tell something.

...and full logs taken after 2-3 minutes after the HyperHDR start. From v19 and v20 to compare them.

[Johnny1982fd]

I know, but i can compile a version by myself. I would like to test LE 12 with V19 - just to see there is a difference.
So, i know it takes time, but i only can pay for it.

Change minimal backlight has no changes in my setting.

The idea was to take phots from my version 19, install v20 and change these settings manually as the same as i have it on v19.
(No Import via json File)

Hmm, here is my Config.
HyperHDR-19.0.0.0-Backup-2024-03-22.json

[awawa-dev]

I restore it on my system. You had backlight completely disabled and by design (in every version) anti-flickering filter is disabled when the target from the grabber for a single LED is real black color. Which is possible only when the minimal backlight is disabled. I tested it only few minutes on some anime series (after setting minimal backlight to 2) and didnt notice flickering on my system that is related to some discrete changes on similar frames in series due to colors dithering/averaging error. But of course HyperHDR reacted very fast for such smoothing settings, maybe you need to increase the delay although it was the same in v19 but the LED processing was optimized and it's faster now.
I am not responsible for the WLED driver because it is not recommended by HyperHDR and it is even in the wiki, in version v20 the protocol was changed to Audio Reactive, which is in the v20 changelog, although it should not cause any changes at least WLED documentation doesnt mention anythigh about it (UDP stream remained the same only port is diffent and you should notice a change on your device WLED panel between v19 and v20 when the stream is active)... although I don't know for sure, I don't use WLED... there are a lot of settings that can affect LED rendering and I cant help here.

[awawa-dev]

BTW Gamma red/blue/green were also non-default (2.2) and extremely distorted colors... in HyperHDR we use 1.5. Neutral is 1 (grabber color = LED color).

more chances for the real black color (0) and disable the anti-flickering filter for a single LED when the minimal backlight is disabled...

Verify if the black border detection is still working for you.

didnt change LUT settings in V19 or 20.

that's not what I asked for

Ok, i guess i dont understand what you mean, can you give me a little bit more infos?

Before i missunderstand that point ... these option is meant, right?

If this is disabled, theres no Anti-Flickering filter.

[Johnny1982fd]

Im still a little bit testing with Gamma ...

is in V20 an expert mode like V19? (didnt find it)?

[awawa-dev]

there are 3 gammas in the processing tab (reg/green/blue). try to set them to 1. And disable max brightness in WLED.

[Johnny1982fd]

HyperHDR overrite settings. Brightness is 220/255.

Question: Why do you choose 1,5 Gamma as defaut? Isnt it 2.2 ?

[awawa-dev]

HyperHDR overrite settings. Brightness is 220/255.

you set it in the WLED driver in HyperHDR.

Question: Why do you choose 1,5 Gamma as defaut? Isnt it 2.2 ?

Does your 2.2 come from Hyperion NG? Why they use such high value? Have no clue. Why 1.5? Because I like it more and is more neutral that 2.2 and doesn't ruin dark scenes. And the billion-dollar question: what gamma do LEDs have? Because we know it's 2.2 for monitors. And they certainly don't have the same one as LEDs.

[Johnny1982fd]

I have found some settings which are OK for me.
Discussion can be closed.

Thanks for the good support!
