I have been looking in these forums for the exact problem but can't seem to find any matches. When rendering in Voukoder, it won't start due to an unknown error. If my specs are needed, it is an RX 7800 XT, AMD Ryzen 5700x and 32GB RAM

This can happen due to a video format error. Meaning your video settings in your NLE may be incompatible with the FFmpeg encoder you're trying to use. Classic example: trying to encode interlaced video using NVENC.

I'm having the same issue with Vegas Pro 22.
Performance test works (I assume this means that FFMpeg that in %PATH% works fine).
However, when rendering I'm getting this error:
My Voukoder Pro settings:
How I can investigate what is cousing the issue?
Any logs available?Thanks.

FFmpeg is working fine. Otherwise the designer app wouldn't work properly.
Please copy & paste the log file here:

Checked log and fixed the issue. Thanks.
P.S The issue was caused by option "profile: high" that I added. Not sure why it does not like the option:

It should be all in lower case.

I tried the lowercased and the outcome is exactly the same.

Are you using the latest version of FFmpeg?
-
Not the most recent one. 7.1 gyan's full shared build

Some older versions had issues with the "profile" option. I had to update my FFmpeg to fix that issue.
-
Thanks, will try to update to the most recent release version (7.1.1)
-
Confirming that after upgrading ffmpeg from version 7.1 release to version 7.1.1 release the option `"profile": "high"` is not causing issues any longer.
Thanks.
