Once you’ve anchored the timespan where drifting occurs, with the TWO keyframes, you will not experience the issue you’ve described. The Adjust Track module does what it says – it adjusts the ‘original’ tracking data. You seem to have missed the part in step (2) where you create the second keyframe in the Adjust Track module. Hi Gardner, based on your post, I don’t see where you’ve followed my instructions in this thread –.
The track is good enough that if I used just the translation data to roto in AE, I’d only have to adjust a few mask keyframes on my matte layer, but this Adjust Track for a corner pin is driving me b-a-n-a-n-a-s.ĭoes any of this make sense to anyone? Would it help if I posted a video screen cap of this actually happening? I’ve heard it said that if this happens, then you probably just have bad initial track data, but I really don’t think that’s the case. It seems to me like Mocha isn’t interpolating keyframes properly, but in reality I’m assuming that it’s just not interpolating them as I’m traditionally used to keyframes being interpolated in AE, etc. Sometimes I’ll have to set many keyframes, because even if I’ve adjusted correctly, the point just jumps right back out of place on the very next frame.
So I go to the worst place in between, set another, etc. But then in between the two set keyframes, there is still a bit of drift. I’m setting keyframes as I normally would – adjust point to the correct location, move through the clip until the point is at it’s “worst” drifted place, then adjusting again, and so on. However the problem is that sometimes, after adjusting a point that has drifted back to where it should be, the point then immediately jumps back to where it had drifted to on the next/previous frame. After setting the Master All, I go through and adjust points as usual. The initial track is ok with a little bit of drift, so I jump into the Adjust Track module. I’m tracking a card that someone is holding (3′ square) to insert video onto it using a corner pin. I’ve run into this problem before and always just dealt with it, but I really want to know what’s happening.
