Hi AvtomatAK, let me know if you're interested in this project. We have 2 quicktime videos that need to be merged. One is a live recording of a concert with a video screen, and the second is a new, better recording of just the video that was on the screen. Mainly we'd like you to overlay the new video (imagery from Iceland, choreographed to classical music) over the screens in the original video. We're seeking a few other adjustments, if possible: improve the audio quality a little, lighten the stage, and also there's around 5 seconds at the beginning that need some masking. I'm going to sleep soon but I will look for your reply sometime around this evening, Polish time. Hope to hear from you, and thanks in advance!
