            Bug ID: 470499
           Summary: Wrong value is passed for the "frame_duration" option
                    for `libopus`
    Classification: Applications
           Product: kdenlive
           Version: 23.04.1
          Platform: Other
                OS: Linux
            Status: REPORTED
          Severity: major
          Priority: NOR

***
NOTE: If you are reporting a crash, please try to attach a backtrace with debug
symbols.
See
https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports
***

STEPS TO REPRODUCE
1. Create a video
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.

SOFTWARE/OS VERSIONS
Windows: 
macOS: 
Linux/KDE Plasma: Arch Linux (latest updates)
(available in About System)
KDE Plasma Version:
KDE Frameworks Version: 
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.

The crass error message in more detail:
