So, as soon as this posts I'll probably see five how-to's on the "Discussions like this" box, but here goes...
I've been using the chroma key effect successfully to get different backgrounds behind a subject, but now my daughter wants to add a "flying" effect. I.e., we want to film her running in front of the green screen and jumping, and we have a harness/pully system to help her jump higher and faster than six year tolds tend to naturally.
Is there a name for the technique used to edit the harness wire/rope out of the clip, or could someone point me to a tutorial? I've been searching online, but using terms like "fly" and "wire" I'm returning all sorts of diverse subjects.
Try the Garbage Matte effect...this can be used to eliminate the "wires" and the keying to eliminate the background.
