Did you try to play the file even though the job failed? It appears to have possibly created a valid despite the failure (false negative)? Otherwise, I do not reproduce it on my M1 Mac. If you are only doing H.264 output you do not really need to use hardware encoder on a modern powerful machine (little to no benefit).

When the job fails the file is also aborted.
But, it is OK, all works fine without the hardware encoder.
Thanks.

How do you know? Your log seems to indicate to me otherwise.

When the job failed in UI, I kept the UI open for like 15 minutes. The video export normally takes 2-3 mins. The exported file only had like 1 frame in it.
