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.

Version 12beta6

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.

Fixes / Changes

• Upgraded from FFmpeg 5.0 to FFmpeg 5.1
• Enabled FFmpeg log during initialization
• Adapted SVT-AV1 to new parameter interface and added CRF to rate control options
• Video side data: Adjusted MDCV luminance limits (Min: 0-5, Max: 5 - 10000)
• Switched to NVENC SDK 12
• Added NVIDIA AV1 encoder for RTX 40 series GPUs
• Added back MFX integration (Media SDK 2021 R1)
• Added asm parameter to x264 and x265 encoders
• Added "tune" option to nvenc encoders
• Added more options to svtav1 encoder (Thanks to Kleinrotti)

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.

Will be included in version 12.

Maybe someone can volunteer and add the other relevant params to https://github.com/Vouk/voukoder/…libsvt_av1.json ?

QuickSync encoder initialization errors

I'm in contact with Intel about that.

My question about the hevc_nvenc option "tune" that enables lossless encoding has been deliberately ignored and I acknowledge that.

It's included in version 12.

Yep, this will be included with release 12.

Just switch to MOV in Voukoders Output settings:

Did you read the release notes?

Nice to hear. Some people see these qsv encoders, some don't. I am in contact with Intel about that.

Latest build: https://github.com/Vouk/voukoder/…der-12beta4.msi

Can you try this build and check if h264_qsv and hevc_qsv are back again?

Edit: link removed because new version is available.

Ok, found the issue why QSV is not working at the moment. Can you tell me the last version of voukoder where QSV was working for you?

NVENC

We need to wait for NVIDIA to release the updated drivers (520.0 or later).

I've updated the beta versions change log.

QSV

Can you try updating to the latest Intel video drivers?

Can you ...

1. Enable "low level debugging" in voukoder settings
2. Open Voukoder settings in premiere
3. Send me the most recent log file in C:\Users\Daniel\AppData\Local\Voukoder\Logs

Voukoders translations: https://crowdin.com/project/voukoder

The chinese translations are only partially translated for quite some months. I translated the remaing ones now automatically. But they are not included in voukoder yet, because someone has to proofread them first.

P.S.: The automatic translation also works for other languages and can reduce the work of translation volunteers.

It will be always slower than FFmpeg directly. Cos the premiere project needs to be rendered first before Voukoder can encode the frames.

Unfortunately AMD is not that optimzied in Voukoder. I don't even have a proper AMD GPU.

I'm partnering with both Intel and NVIDIA but never even got a reply to my emails from AMD.

Edit: I really wonder who all quietly reads this forum.
