Tnx Walter for your proposed solution, I am not that familiar with JPEG sequence workflow, I have to look into some documentation but we made new compressed file that was also great looking and I managed to pull out the image and remove that nasty flickers on models suit and as you said edges came very hard to straighten but with a help of refine matte pluggin that was corrected. Overall I am not very happy with result yet again it is far better than it was in previous tests. My conclusion is that it is possible to downgrade ProRes to signifficantly smaler file size and after rendering out from AE quality can be acceptable if final clip is for web video not for broadcast. Now I am challenged with another type of nastyness called BANDING on models suit, effect that looks like areas of suit are ringing, so I tryed to add noise, grain, and I can’t reduce it at all…
