What I've Accomplished:
I've successfully created a time dilation effect with simple panning shots using this workflow:
- Track and stabilize the background
- Apply time dilation to moving subjects (which correctly positions them in 3D space)
- Reverse the stabilization to get the final composite
This works perfectly for simple camera movements. You can see the results in the before/after images attached.
Current Challenge:
I'm now trying to achieve the same effect with a more complex camera move - specifically a camera that's both pushing forward and panning while subjects move through the scene.
Technical Setup:
- I've successfully tracked my camera data
- Created a ground plane and null object
- Attached a tracking shape to my null (visible as the white box in Image 1)
What I Need Help With:
I need to stabilize the footage so that:
- The tracked shape (white box) remains perfectly static in 3D space from first to last frame
- The footage should rotate and move around this fixed point to maintain the shape's perspective
- When I later apply time dilation and reverse the stabilization, subjects will appear in their correct 3D positions regardless of when they appear in time
For example, if a roller skater is time-dilated so much that they appear in frame 1 when they should be far down the path (as in frame 100), they should still be positioned correctly in 3D space.
Any suggestions on how to achieve this stabilization with a moving camera would be greatly appreciated!
