STEPS TO REPRODUCE

2. Try to render using SVT-AV1 (`libsvtav1`) as the Video encoding and `libopus` as the audio encoder 

OBSERVED RESULT
Render failed.

EXPECTED RESULT
Render to complete successfully.

Qt Version: 5.15.9+kde+r154-1

ADDITIONAL INFORMATION
I have created a custom render preset using the SVT-AV1 encoder. I have bother tried from scratch and by copying the existing preset of AOM AV1 and just changing the video encoder. In both of the cases, I cannot render as it seems that a wrong value is passed for the option "frame_duration".

I have tried to manually set the option in the "addition parameters" section but I get the same results.

It is worth noting that I have the same exact problem in Shotcut so maybe what is used underline in both these editors causes the problem. Also, I'm able to find a work around, using the method [here](https://gitlab.com/AOMediaCodec/SVT-AV1/-/issues/1958). Yes, this issue was create from me and I found help.

So another theory is that as the custom packages work, this may be a problem with the default packages of Arch Linux. But I wanted to post and find a solution because compiling so many programs in every release will just be a pain so this must be addressed cause if the later is the case, I will not be the only one that has/will have a problem and I/we/you need to talk with the team on Arch Linux to find a solution.
