There is still an issue with the VEGAS Pro that I am not able to detect if it sends an alpha channel. I'm waiting for Magix in this matter.

So is this side data issue fixed for you in the beta?

After sorting out the last NVIDIA AV1 issues this will hopefully be the last beta version before releasing the final version 12.

Voukoder 12beta7

Make sure you are using the latest connector for your application(s). For using NVENC (SDK 12) encoders driver version 520.00 or later is required.

Download: https://github.com/Vouk/voukoder/releases/tag/12beta7

Fixes / Changes

• General
  • Sped up opening the config dialog a bit
  • Enabled FFmpeg log during initialization
  • Video side data: Adjusted MDCV luminance limits (Min: 0-5, Max: 5 - 10000)
• FFmpeg
  • Upgraded from FFmpeg 5.0 to FFmpeg 5.1
• Encoders
  • libsvtav1: Adapted SVT-AV1 to new parameter interface
  • libsvtav1: Added all options to svtav1 encoder (Thanks to @Kleinrotti)
  • libx264, libx265: Added asm parameter to x264 and x265 encoders
  • libvpx, libvpx-vp9: Added pixel format yuva420 that supports an alpha channel. Note: with vp8 you have to set "Alternate reference frames" to "Disabled" to use it
  • NVIDIA NVENC
    • Switched to NVENC SDK 12
    • av1_nvenc: Added NVIDIA AV1 encoder for RTX 40 series GPUs
    • h264_nvenc, hevc_nvenc, av1_nvenc: Added "tune" option to nvenc encoders
  • Intel QSV
    • Added back MFX integration (Media SDK 2021 R1)

They should be back if you update your nvidia drivers to a version greater than 520.00

Please try if version 12beta6 fixes this issue.

This can't be fixed in a short term solution. I will design the successor app in a way so multioutput is possible.

It seems your system is highly limited by your 2(4) Core CPU and especially only 3,5 GB of ram. To fully utilize the fast nvenc encoders sometimes even 16GB is not enough.

Can you ...

• Provide me a voukoder logfile (see pinned thread in thsi forum) with low level debugging activated
• Tell me the steps on how to reproduce this issue?

Added it for the next release.

Note: with vp8 you have to set "Alternate reference frames" to "Disabled" to use it.

This issue will be addressed in the Voukoder successor app i am currently working on.

Can you try a higher value for "Quantizer"?

I will add that pixfmts.

Edit: Ich habe es nochmals überprüft: Alle in FFmpeg verfügbaren Parameter des AC3 Enkoders sind aktuell in Voukoder verfügbar. Weitere Einstellungen (zur Dynamiksteuerung) sind derzeit nicht möglich.

Weitere Bitrates kann ich hinzufügen, allerdings überlege ich dass gleich durch ein freies Eingabefeld zu ersetzen.

What settings / config options are you using for av1_nvenc?

-qp                <int>        E..V....... Constant quantization parameter rate control method (from -1 to 255) (default -1)

Checked it again. It seems so, yes.

The lookahead parameter is actually a boolean parameter. So it can only be 0 or 1.

  -look_ahead        <boolean>    E..V....... Use VBR algorithm with look ahead (default false)
  -look_ahead_depth  <int>        E..V....... Depth of look ahead in number frames (from 0 to 100) (default 0)
  -look_ahead_downsampling <int>        E..V....... Downscaling factor for the frames saved for the lookahead analysis (from 0 to 3) (default unknown)
     unknown         0            E..V.......
     auto            0            E..V.......
     off             1            E..V.......
     2x              2            E..V.......
     4x              3            E..V.......

Thanks for the detailed info! This seems to solve alot of issues indeed.

I'll have a look at the "look_ahead" issue.

Kleinrotti Thanks for your work! I hade to make a few changes but you can test it here: https://d.voukoder.org/voukoder-12beta6.msi

This requires a major rework of how voukoder implements filters. This will be adressed in the voukoder successor app.

Yes ... I am still working on it.
