Multiple tracking masks in long video clip?

[keithm1972]

I got a five-minute clip of a videoconference. This one guest pops in and out at different times (also in different locations and sizes, as videoconferencing works) who has a logo in his background I want to blur out.

I want to blur out this background logo whenever the guest appears.

I get the basic idea of drawing a mask around the logo and selecting "track mask" for a single clip so I can put a blur effect on it, but what's the typical workflow in a situation like this when the mask appears several times in different sizes and locations? I draw the first mask, but it looks like it's trying to track the entire clip when I start the tracking.

No simple answer here. You need to split the clip and track the individual segments. In an ideal world you might even consider doing the cutting in Premiere and generate new master clips from the relevant bits, then transfer them over to AE so it doesn't have to load the full source clip over and over again.
