Davinci Resolve 21 here with Voukoder 2026.1.3.0
Try to encode only audio with this simple preset:
Can you check please?
Thanks!
PS
Which one is to use?
I'll take a look at it soon.
I'd recommend ac3:
In audio editing and transcoding tools (like FFmpeg or Shotcut), ac3 and ac3_fixed refer to two different encoder implementations for the Dolby Digital format. The main difference lies in how they perform math:
- ac3: Uses floating-point calculations. It is typically faster on modern computers, yields slightly higher audio fidelity, and is the standard default for encoding.
- ac3_fixed: Uses fixed-point math. It is designed for older processors, embedded systems, or devices that lack a dedicated floating-point unit (FPU).I guess if you have video clips on the time line DaVinci Resolve is also rendering and sending both audio and video to Voukoder Pro, even if video track is then ignored. You can try to disable the video export in DaVinci Resolve. Is it better then?
If you have no video tracks in the timeline it doesn't render it and does not send it to Voukoder Pro.

I just tried it.
If I disable all video tracks and start the render, the speed is perfect.
If I enable the video tracks, the render time increases dramatically. It looks like Voukoder is processing the video as well.
Example: 1h 40m project with 4 video tracks, audio tracks, and 2 subtitle tracks.
Video tracks disabled: 1m 14s render time
Video tracks enabled: 40m+ render time
