trying to video merge effect a person v. car collision scene, but has a nightime (dark) background. When I action video merge I have added several video tracks to remove black pixellation (not sure on term here), but still remains, particularly at point of car entering scene. Guessing I need to use one of the matte effects (which is also new to me) as well, but welcome any advice on way to remove and/or fix.
I have also tried to do the same scene merge in CS6 After Effects but for some reason I can't activate the layers to merge, even after watching a few utube tutorials from CS5...not sure what I'm doing wrong or if the dark background means I need to take another approach.
Videomerge is designed to remove an evenly-colored background (usually a blue screen or green screen) from a scene shot in a studio -- similar to Chroma Key.
Is this what you're trying to do?
If not, can you post a screen capture of the scenes you're trying to merge together and describe how you're trying to combine them?
If you have AE, at least CS 5, then you have a great tool - the RotoBrush. See this tutorial: http://blogs.adobe.com/aftereffects/2010/04/roto-brush-in-after-effect s-cs.html
