I’ve got a sequence of my film that has bedeviled me as well as the software developer of PTGUI (Panoramic stitching software).

It’s a 10K timelapse sequence shot over 11 days created from 5 stitched 5D Mark II raw files. The stitching is done in PTGUI, however it appears impossible to fix according three of the best stitchers out there and the software developer. You can see it raw test from 1 day here. It’s really hard to see on web video but watch the upper part of the image and stars blink in and out. It’s a thin line or zone where star positions jump on the bad stitch line from the panoramic warp.

I need to see if there is better method that trial and error to precisely find the line as you can only see it and therefore mask it while the clip is in motion. I’m not aware of any way in AE to mask a moving clip nor can think of any way to simulate it on a still. As its stars at 10k, I need to be nearly 1 pixel accurate in masking the region to apply the fix (time-remapping layers) to fix this stitch error.
