RTX RapidHDR AI - Sync issue between the picture and sound

thiel-einkaufen1441413

I testet all possible Settings on RTX RapidHDR AI v: 4.0.7.0 with DTS and Dolby Sound. Im on AMD CPU an 4090 v:595.79

No matter which settings I test, there’s always a sync issue between the picture and sound in the finished video. At the beginning of the finished video, the picture and sound are synchronized. After, for example, 120 minutes of recording time, the sound lags behind the picture by almost 2 seconds.

Can anyone confirm this problem and/or suggest a solution?

First HDR is not real this is fake here, second is it getting worse over time or not

At the beginning of the finished video, the picture and sound are synchronized. The further you skip ahead, the further the sound lags behind. After two hours, the sound is about two seconds behind the picture.

thiel-einkaufen1441413 then this is a bug in the SW for sure, but no surprise since this is fake anyway, you need to go and try the real thing with no bugs, if you check reddit on the AI upscaler forum there are good recommendations and explanations there.
Most likely the length of the output is not the same as the input as they add or remove frames as part of the process, known bug of the Nvidia RTX HDR SW which is available to everyone for free and is faking HDR
