Object Removal

[Tero Ahlfors]

Looks like a tough one. Do you have Mocha Pro? The remove module can work with multiple clean plates and keep the transforming perspective in check.

I only have Mocha AE.

If you go to:

I’ve uploaded the shot. Can what you’ve suggested be done in Mocha AE?

Looks like Mocha Pro and the remove module is the answer after a bit of searching. Thank you!

You can try it with the Mocha Pro trial. But you can’t open trial version projects in the full version.

mochaPro has the Remove Module. The shot isn’t as bad as I had imagined. However, the lens flare may interfere with the tracking engine. Multiple clean plates will be ideal as mentioned in an earlier post but you will find it incredibly difficult to match the clean plates due to the patterned floor.

There are just too many things wrong with the clip from a production POV. My thoughts are that tracking wasn’t thought out as a requirement when this was shot.

I suggest that you check this out with the good folks at Imagineer’s forum on their site.

Good Luck

Thanks Guys.

I’ll try the forum and the trial. Might just have to be a shot to let go or send off to a 3d app and spend hours on the shader.

You could also roto the girl and then replace the entire floor with CG. This may be a better option than removing the tyre marks. But let’s see what the good folks at Imagineer suggest.

Your biggest problem will be the lens flare.

But otherwise, you need to make a synthetic plate (2D) that is basically an overhead view of the land that needs to be painted out, and paint out the tracks on this one static layer.

Then track the shot using a 3D or 2.5 D tracker

Orient the synthetic element to match the real ground.

Use a mask to reveal the synthetic element.

Put the main plate on a layer above, and use Multiply to add the shadows back in as necessary.

You can probably ADD in back the lens flares using a layer of the main plate, or use a plug in to add in a simulated flare to cover.

You can do this with Mocha AE for the 2.5D track, use Photoshop for the synthetic plate, and create the masks in Mocha or in AE. However, I think you’d be happier with a 3D track for the synthetic replacement element.
