Edit: To clarify, I know that the original source is exhibiting the jumps in luma values. The whole point of it all is that there's a lot of videos like this out there to "restore" using this effect. In order to perfect this feature, which is amazing already, it would be great if it perform the suggestion.
Original Post:
There is an issue with VEGAS colorization. In certain videos, the effect seems to struggle maintaining luma values at a consistent rate thus introducing a subtle flicker. I studied the footage closely to look for faults in the take. It’s a well explosed film but - it’s still shot in the 1960s
I won't pretend to understand how A. I training works but if this is an A. I problem - I would suggest an option in the effect to "freeze luma values” and keep it consistent. Otherwise, it sort of behaves like a bad “Auto-level” effect, which isn’t ideal.
