Export with 750x100 resolution

Hello,
I'm pretty new here. I am trying to use Davinci to create movies with an unusual 750x100 resolution. When I set such values ​​in DeliverPage, the effect is scaled and blurred. Perhaps because of a different resolution set in File-> ProjectSettings. There, I can't set this resolution for the timeline. Is it possible to generate a high-quality movie in this resolution?

The smallest horizontal or vertical resolution you can do in Resolve is 250.

256. OK, that's what I wrote yesterday. But, the limitation applies to the timeline only!

I wanted to make sure, and actually I can export 750x100 as ProRes on the Mac. The quality is OK if seen at the same tiny size. And use a multiple that works for your timeline, downscaling in Deliver is no problem.
So, try other codecs if you're on a PC.

I was unable to export in 750x100 resolution on windows. The quality is very good, but I have huge black margins in the film. However, I managed to do it in the 1920x256 resolution (about two times higher). This resolution i can set in timeline. Then I scales the files to 750x100 in another program. Thanks for your suggestions.
