I was wondering if I have to update the visual preview to use deflicker. Like if I want to use deflicker like it was in LRT3 where I didn't see what was done until I render video. It just takes along time to update the visual preview. Might be a dumb ? as I am pretty new to lrt. Thank you

If you want to use the "old"m simple deflicker, you'll find it on the "basic workflow" tab, no problem.
