Unfortunately Voukoder can only export max. 1 video and 1 audio track. The rebuilt version is designed to handle as many tracks as the container supports.

Unfortunately Voukoder is not able to get this information. I've had discussions with Magix and the assured me they'll work on this topic.

Can you please try version 0.10.0 of the DVR connector with 24bit audio and give me feedback?

As I've said above, FFmpeg doesn't understand the 24bit format Resolve outputs. It expects 24bit samples stored in a 32bit sample buffer. So I need to convert it to 32bit first. It's kindof difficult when you don't know how this 24bit data is stored exactly. I was working on it over the weekend, but I just got some distorted sound so far.

Voukoder 12

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. Enterprise / Quadro users can use the studio drivers: https://www.nvidia.com/Download/drive…x/193884/en-us/

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)

Please install the studio drivers on Quadro machines. Enterprise drivers are said to be released end of november.

NVIDIA Studio Driver | 522.30 | Windows 10 64-bit, Windows 11 | NVIDIA

Download the English (US) NVIDIA Studio Driver for Windows 10 64-bit, Windows 11 systems. Released 2022.10.18

www.nvidia.com

Only the paid "Studio" version supports external plugins.

Do you use the free or the paid version of DVR?

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.

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.
