The strange thing is: There are no difference in the voukoder-code between those versions. I Just updated the FFmpeg libs.

What player do you try to play the files with? esp. some hardware players are only capable to play encoded files up to a certain "level" (i.e. "4.2").

It's playing perfectly here.

What player do you use?

Can you render me a short non-playable clip and send it to me? I just need a couple of frames.

Does this version fix the issue?

The topic speaks for itself I guess.

Working von VEGAS Pro support right now!

Thanks. I'll investigate this on the weekend.

Regarding the 3. point: Can you open the scene and click on the Test run button and copy the log in here?

P.S.: It's a good practice to test your scene first before you are actually using it in your NLE.

Can you enable low level debugging in the settings and share the logfile again?

Did anyone of you test it already? What are your impressions?

The solution is the same as with message #3 above.

[12:42:53] Interlaced: Top first

The newer NVIDIA boards don't support interlaced videos anymore.

[11:18:25] Timebase:        529191533/-1841018880 (-3.48 fps)

Please select the correct frame rate in the video section in premiere.

The developer also has nothing more to add to what has already been said.

I tried to reproduce this with the static smpte bars and it looks like this:

To me it looks like how good the codec is able to compress the source footage. With complex material you get a high bitrate, with very simple video you get a low bitrate.

Can you try if this version fixes the issues?

Release 13.2beta1 · Vouk/voukoder

Release Notes This is a BETA version and not intended for production use! Make sure you are using the latest connector for your application(s). For using NVENC…

github.com

I updated from FFmpeg 5 to FFmpeg 6 in these version. I didn't change anything else.

I might try to make a new build with a recent version of FFmpeg and we can check the results.

According to the devs the difficulty is NotchLC is not compatible to FFmpegs GPL. That's why nobody is including it.

Please update your NVIDIA drivers.

Yes, I can confirm that. Need to investigate when I have time.
