Video tracking: fixing interruptions (best practice)
(I've looked at a lot of video tracking training and done a fair bit of it. But I haven't yet found a specific discussion of my issue, so here goes. It would seem to be a common one. Maybe someone can give me a pointer.)
I'm tracking a video with quite a lot of nice features. But a runner passes through the scene and the moving shadows briefly interrupt the automated tracking. (Tracked features are still quite visible to a human.)
It seems possible to fix this manually, but I'm not sure I'm doing it the best way. When the automated tracking stops, I can re-enable the track with the "eye" icon and manually re-position it. (The x/y curves in the graph editor are a helpful hint - make the curves smooth.) Then I can try to start tracking again from that point. Repeat the procedure until smooth curves are obtained all the way through. I see individual keyframes appear in the dope sheet for manual adjustments, but I guess they are equivalent to the automatic ones.
This is a little tedious, but could be worse. I've tried several uglier workarounds. Tweaking of tracker settings would seem to be limited.
Thanks in advance.
