If you’re having trouble with 3D tracking in After Effects, try the following:
1. **Improve Footage Quality**: Ensure your footage has good contrast and distinct features for the tracker to latch onto. You can enhance this by adjusting brightness or adding a slight contrast boost.
2. **Use the 3D Camera Tracker Effect**: Apply the 3D Camera Tracker to your layer and let it analyze a longer segment of the footage for better tracking accuracy.
3. **Check Tracking Points**: After analysis, review the tracking points for stability and proper placement. Delete any unstable or irrelevant points that might be causing issues.
4. **Create a New Camera**: Once tracking is successful, generate a new camera from the tracker to match the scene’s motion accurately.
These steps should help resolve common 3D tracking issues in After Effects.
