I am restoring video taken in the mid 1980s with a camera that had a faulty blue channel. Blue is low overall and has significant areas where there was almost no blue. I was getting fairly good results by doing a general grade then isolating objects/people with power windows, motion tracking, and grading within the windows. I did most of the window tracking manually.
Over the last few days, significant parts of the tracking data have become corrupted. Some tracking points change position. I've counted two to seven points on a window that have shifted out of position considerably. Sometimes the position of the mask has shifted sideways.
This seems to occur as I progress through a clip in frame mode moving points and thus adding key frames. I'll change points/create key frames every few frames or seconds. Sometimes I will back up and change the position of points at a key frame and then continue forward. Other times I may delete a set of key frames and redo a section. Somewhere is this activity, points in key frames at the beginning of the window tracking move even though they were not touched and were isolated by many other key frames. I would not expect key frames and interpolations that are more than one key frame from a new or changed key frame to be affected.
Ive corrected a couple of the corrupted windows by stepping through each key frame and moving points back into position. I'm writing to ask for help because my corrections are now corrupted.
To try to isolate the problem, I've loaded different backups (my system creates backups every 5 minutes.) Last night, project copies created from the first two backups showed the same problem. The project copy from the third backup was not corrupted--until today. Just opening the project seems to have corrupted the same windows in the same way. Also, opening previous versions of the project that I saved manually a few days ago show the same corruption. I swear I saw the issue go away and then return last night, which would seem to indicated a software issue.
Help! Any suggestions on how to get and keep a clean window track? I've lost many hours of work.
Thanks,
Steve
