Out of nowhere, Mocha Pro plugin (2019.5 in AE 6.1.1 on macOS 10.14.5) said:
Unable to Compute Warp Homography and Camera
While in the Insert Module (for a track and insert that had had no issues previously).
What do I do about this?
I have tried to delete and reimport the PNG file to insert. When I did that, then I got
Layer Overlay Error: Failed to render warp point.
I want to emphasize that this is a track and insert that I’ve had no issues with multiple times of going into Mocha Pro, making adjustments, going back to AE, testing/viewing/rendering out, and back in again. All without any issue.
I have been finding that if you go back and forth between AE and the MP plugin too many times, there is a certain point at which MP will crash or just lose its internal connection to its own database somehow. I don’t know what happens, but several times in the past two weeks I find the plugin just sort of gets too confused and it will lose its place or not know where I left off and will simply stop working.
This error is an example of Mocha getting confused. I’ve gone back and forth between MP & AE and have had no problems with this particular insert. It’ll track wonderfully, I can insert an image or clip (the weird looping thing notwithstanding) and it will be fine then boom, out of nowhere, Mocha Pro just can’t track or follow things any longer. It’s very hard to pin down but it’s happened enough times that I’m now getting very antsy about how often I make corrections to a track or an insert. Over 10 times of making adjustments and Mocha will either crash (there seems to be no crash reporting mechanism built-in) or it just can’t stay connected with its internal database.
