Daniel,
thanks for the detailed answer. Here’s a YouTube link to the part of my video. Please don’t pay attention to the quality and color gamma – it’s obviously changed/compressed by YouTube. The original one was shot in resolution as much as 3840×2160 in ProRes HQ422 (fps 29.97 but I guess it doesn’t matter). Also I have uploaded my album cover we’re trying to “re-construct” in our video. burgoci-bdts.jpg There are two nimbuses (halos) on the picture – first of all I need to create the one that is hovering ABOVE girl’s head (not BEHIND head)… Well, that’s it I guess. Hope you’ll be able to suggest me something. P.S.: Yeah, I tried to track her head’s moving in Mocha AE, but instead of getting the result in 3D coordinates, I received just a Corner Pin effect.
