I was never been able to encode on AV1 with Kdenlive but I didn’t give it much thought.
Tho now that I took a look at the output log (and I know what opus is) it doesn’t make much sense.
[libopus @ 0000023f35791180] Value 16666.000000 for parameter ‘frame_duration’ out of range [2.5 - 120]
[libopus @ 0000023f35aa9900] Value 16666.000000 for parameter ‘frame_duration’ out of range [2.5 - 120]
So if I render without audio how can opus crash?
Seems like a bug to me.
