creating red/green flashing light effect
Hi,
I’ve been asked to edit a short film that sounds interesting. However, a key part of it is that the main character has a device attached to his neck which flashes green or red at different stages. In the footage there is no actual flashing , just a dummy device which the effect needs to put onto in editing (its just a small thing, I’d imagine it looking like a flashing LED). The rest of the film will be in black and white with just this flashing light showing in colour.I’ve been using Final Cut for a while but only doing quite basic editing, I have no experience of adding effects like this.
Does anyone have any advice on how this might be achieved and how difficult it will be?

What you have here is a potentially complex tracking problem. You need to track the band so that you can make your lights follow. Not seeing your footage, my assumption would be that there is 3D motion going on with your subject, ie. turning, which makes matters even more complex.
If you want to try tracking inside FCP take a look at Mocha. This whole procedure though is a bit advanced.
But, there’s also the painstaking method of manually moving your lights, and if they are blinking in some way, that would give you little windows of “cheat” time. So it would be relatively easy.
Have a wonderful day.

“I’ve been asked to edit a short film”
sounds like you;ve been asked to do the vfx as well.
if that’s not your thing, suggest they find someone else.
you can just EDIT the film, ignoring the light issue,
or using some simple substitute if there are story issues involoved.nick
