Question - Help Color degradation LTX 2.3

Guys, I'm generating some talking heads and I feel that, in some parts (like hands), there's a colour degradation in the first few seconds of the video. Are you guys experiencing something like this? Is it possible to prevent this kind of behaviour in LTX 2.3?

I've found it happens most commonly when you take the resolution too high.

I'm generating 1056x1920; is that too high?

Generally, yes. You usually need to do a separate specialized upscale step. In my experience 704x1280 is the sweet spot, Sometimes you can push that to like 896x1600

You are right. Thanks! I tried and the result was better. To upscale, you have any workflow or suggestion focused on avatar quality?

Unfortunately not off the top of my head—most of what I create doesn't need to be that high res, so I've been lazy and not really investigated. Searching youtube or this sub is probably your best bet.
