Can you look at adding a simple Brightness/Contrast and maybe Saturation/Colour Adjustment panel within VAI? It would be so helpful to be able to adjust these parameters, particularly for old videos, before any other process is performed.
I have made the same suggestion in the forum. This would be a one time implementation and does not affect on future updates, except UI changes, so I think it’s worth to do this once.

I also don’t understand how such simple functions are not included in this so called “power” program? It is really disappointing.
I was trying to do this yesterday using the eq filter via CLI. But it’s not part of their ffmpeg build. So i had a look around, and it’s indeed listed under GPL Licensed Filters. So i guesss that’s why. I’m not super familiar with what others filters ffmpeg can use to set gamma, saturation, brightness, contrast etc. I’ll paste the filters generated with their ffmpeg build below, and perhaps someone else can point one or more out. I don’t see that making such a filter themselves would be overly complicated considering they’ve made models and are considered one of the leading developers in Video Enhancement using AI.
Filters in their most recent build (removed all the Audio filters as i passed the limit of amount of characters in a post - which is 32 000 for anyone interested lol):

I guess there are a few filters like colorbalance, colorcontrast, colorlevels, colormap etc. However, I’ve never used them so i don’t know how well they work or what they actually do.
Also, running CLI is not really the reason people purchase TVAi.
Thanks for looking into this though. I’ve been wondering about it since people bring it up every few months.
