Shape Data glitching, how to correct?

Same frame. Why doesn’t the shape from mocha translate correctly into AE? The frame rate and dimensions are correct. The 10 seconds prior to this glitch starting are correct. Then it goes off track.

Why is it going off track? Why isn’t it showing what the shape literally is in mocha? How do I get this glitch to go away?

Thank you for help and response.

It’s hard to see what is going on from the screen grabs, but my guess is your tracking data is skewing too far and throwing the shape off on export.

When you view the blue surface tool for the layer, does it stay solid and visible through the whole sequence or does it skew wildly or disappear? If so, you may need to manually roto part of the wing, as the tracking data is distorting the resulting shape data.
