If you take a look at the clipboard data (paste into a text file), does it have a section that contains “extra” information? pI3 is looking for very simple data, and if there’s more complex data there that may be where things go wrong.
What if you do a very small track… like 30 frames or less? Does it still work for a while then go bad in pI3? If so, paste the clipboard data in a post here so I can see all of it.
Can you track a point with Mocha instead? (I’m not familiar with it)
What about using AE’s motion tracker — does that work for you or does it have the same problem in pI3? (As a test)
