Flickering?

[Kenny Powerass]

I can’t speak as to whether or not you’ll lose quality. I gave up on the flicker filter for another approach as the I find the flicker filter to be a little ‘hit and miss’.
Now if I encounter flicker I duplicate the clip onto the next track and offset it by one frame. Then I drop the opacity on the top clip to 50%. It can get tedious in a complicated edit, but it usually takes care of flicker pretty well.
