Export ProRes en H265 failles on Apple Silicon

Topaz Video Bugs and Issues

Since I switched from a MacPro 2019 to a Mac Studio M2 Ultra, my exports to ProRes and H265 crash. At the end of the calculation (Proteus and Iris, the two I use), the video systematically stops at 2.15 GB. The original files are between 2h and 3h in 1080p.

Exporting in H264, it works properly on the other hand.

On the other hand, he is not in the file I indicated to him but in the original one.

That’s strange. I don’t do ProRes but very often H256 and never had that fail (also Mac Studio M2 Ultra).

But then I guess the last time I did use anything other than Starlight mini (and then Iris and Proteus as well) was some months ago - so around the first Studio releases.

I’ll test this with a recent build of Topaz Video when I’m at home and report back.

Thank You very much !
It is the duration of these videos that causes the problem. On shorter videos I don’t have the problem.

The devs are looking into this as we have seen it a few times.

In some situations, it was the format of the drive where the file was being written to, but that does not look like the case here.

Will update once we know more.
