Export Movie 61700

Yes, I meant dimensions of odd numbers, but have since had it with all even dimensions also, so i can’t nail down exact conditions to make it fail. I was using rclick top>export movie, when it finishes the file isn’t in the folder where I exported to, but is visible in win10’s “recent files” list in explorer as files with zero size.
Not sure if related but:
Nvidia h.264 codec
changed export destination manually to dektop
Last file it happened on was 1920*1080
No sound

I’m not at the same machine at the moment but I’m pretty certain it’s the most recent 088.
