Hi Matt,
To get it exact, this is Roto work.
You take the footage into the Background
Attribute Manager> Mode> View Settings>Back.
Set your project to the footage frame rate.
Use the Spline> Pen: B-Spline
Set Keyframe recording to Point Level animation (no PSR recording)
Move the time slider to a frame where most of the chain elements are visible.
The Chain has cylindrical connectors (white dots in the footage) start with the element that flies off first, then the second, each gets a click with the Pen, then go to the third element, from there, perhaps use only every fourth dot to click. Press ESC when done.
Now record that to a keyframe (PLA).
Go back or forth 20 frames and move all the points of the Spline to the dots they were sitting on previously. Continue with around 20-30 frames distance. Do it until the around seven seconds are done.
Check for the spaces between two keyframes, adjust and record if needed.
After that, check the spaces between the new and older ones. Until that Spline follows the Chain.
If you want to have it very precisely, use any of the white dots, more work, more precision. The footage itself is not good enough for any motion tracking.
Now make two copies of the Spline.
Delete on the second the first point.
Delete on the third the first and second point.
These three splines contain now all you need to animate the Chain unbroken, and with the spline 1 and 2, you have the two elements fly away positions. The little Cylinder should be animated freely.
Anything else is doable with MoGraph.
I have tested it here roughly, and that would be my way of doing it, based on the challenge to accurately recreate it.
If that doesn’t need to be accurate, please advise. Exact look leaves some kind of room for interpretations. Is the “Phantom Camera” look requested, or the correct position, but with more frames than the given footage.
Cheers
