Looking for a way to remove objects that is NOT Boris

We are shooting video of a busy street scene with multiple moving foreground elements we wish to remove from the scene, so the Boris motion tracking option doesn't seem applicable. Can anyone recommend a software solution that doesn't require tracking?

I'm going to suggest something "Boris" first, then give another solution.

You could try BCC Motion Key in the Continuum Complete package. This will try to reconstruct a background image from multiple frames. There's a tutorial on the BorisFX site.

The other way, possibly without tracking, is to create a clean plate then settle down for some good, old-fashioned rotoscoping. Basically create articulated masks to cut out the foreground elements and reveal the clean background plate.

How do you create the plate? Well, if you can't get a good bit of clear footage when shooting, then it's a fair bit of Photoshop work, blending multiple frames and a good amount of cloning.

I've got a training DVD in production that is all about roto work with Mocha. So I'll just say, that depending on your footage, you could be in for a fair amount of post work. :)

Hope that helps,
Ben

I second the suggestion to try BCC Motion Key. It is designed to do just that without motion tracking by using our Optical Flow technology. There is a new tutorial by Kevin McAuliffe from Pro Editing @ Home

demonstrating removing one person from a backyard. Although, it is not as dramatic as removing multiple people from a busy street his results seem very clean. Good luck!
