Wire Removal with Moving Camera

#1

Hi Guys,

I’m working on this movie for a project and was really hoping for some VFX advice. It would really help me out.

We have this one shot (you can see in the video below) where the camera is tracking from left to right and an actor gets pulled with a rope out of the scene. Now we didn’t have a track for the camera so it was handheld.

I tried to do the same path for a clean plate, but it looks slightly different perspective wise (maybe a step closer).

Anyways, so I am trying to remove the rope from the shot. If you’d like you can take a loot at the video of the 2 shots.

What would be your plan of action to do this?

I’ve tried tried line up some of the lean plate footage by eye frame by frame but when it’s played back it kinda jumps around and is noticeable.

I would greatly appreciate some wisdom and approaches to take.

Tools I have are After Effects, Mocha, Photoshop

Thanks guys,
Tyler

Very hard to match clean plates without motion control !

You need to do this:

Track the several distinct planes (ground, mailbox, plant son background) with mocha.
Create a clean plate for each area, i.e. still frame on photoshop, and using the planar tracking data apply to the respective areas, covering the rope.

Rotoscope the soldier back to place the clean plates behind it.
Apply grain/animate color correction to match background plate on the clean plates if necessary.

or

If you know mocha well, you can do the removal of the wire using mochapro removal’s module.

Thanks for the advice!

I tried out Mocha’s remove tool and it did wonders! I’m still kinda shocked how well it worked.

Greatly appreciated.
