h264 MacOS 11.4 Big Sur, Export Error

[Christoph_HH]

Hi,

When exporting timeline through MediaEncoder 15.2 on an iMac with OS 11.4 (Big Sur) to a h264 file the end of the file is corrupted. The export freezes about 5 -10 seconds before the End.

Identical Timeline on an iMac with OS 10.15.7 (Catalina) does not have this problem and on also Win 10 PC no problem.

Are you able to export a good version from Premiere Pro directly?

[Christoph_HH]

No its the same through ME or PR.

Do you have enough disk space on your target export drive?

Do you have your export range set to "Entire Sequence"? 

[Christoph_HH]

There is 12 TB free space on my my 40 TB storage,

I export Sequenz in/out, but even if I set the out 10 seconds behind the last clip, it does not export to the very end.

[Jeff Bellune]

What are the properties of that last clip, please? Use the free MediaInfo program to analyze the clip. 

What happens if you remove the last clip from the timeline?

What happens if you set the sequence out point to somewhere before the last clip?
