Removing track in dolly shot

[John Cuevas]

I think the “best” way would be to get a clean plate of the floor without dolly tracks in a higher resolution, and camera track/planar track that to your move. If that option isn’t possible, try CC Wire Removal

It looks like it’d be pretty straightforward to do in Ae with a little help from Ben Rollason’s Projection script [link].

Maybe it’s a worthwhile candidate for the Mocha Pro Remove module [link?

Thanks Walter
AE never ceases to amaze!

Only problem I’ve found is that I can’t seem to get a 3D camera tracker solve on the floor. Wall on right, no problem. Probably the lack of contrast?

Guessing I have to use Mocha… can anyone walk me thru creating a proper track using Mocha? Just use the spline tool with default settings and export or?

mocha should be able to track the floor pretty easily. You will want to track from end to beginning and draw a shape around the floor plane and avoid any foreground elements such as the instruments, etc. Then you export your track data.

There are multiple ways to attack your problem from compositing perspective:

1. Track in mocha AE and apply a “painted” patch to the track data. Because you will want to make you patch in perspective, you will want to use “Align Surface” button before exporting mocha data.

2. Track in mocha AE and use the MochaImport+ to stabilize a precomp of the floor, do your paint work, than remove the stabilize. (mamoworld.com has great tuts).

3. OR mocha Pro has remove module that could track in a painted clean plate and match the lighting shifts for a more realistic composite.

Thanks!
My guess is Mocha is the ‘best’ option for this particular shot. Could not get the built in 3d tracker to solve the floor for some reason.

For now have resorted to a somewhat kludgy and imperfect solution but it gets me in the ballpark

I created a luma matte with blurred edges isolating the track
