So...I received V8 today and have installed it. The first thing I looked at was the multicamera feature. I loaded in a couple of video tracks from a project I have just finished to compare the camera switching, with and without. This is clearly going to save a lot of time and bother.

However...I have just realised another issue.

Both these tracks were green screened and the way I did the project in V7 was to put the two backgrounds on their own tracks and switched them at the same time and in same way as I switched the camera angles, by using envelopes. I see now a simpler way to have done it (and to do it in future) would have been to render out each camera with its background before doing anything else, and then use these rendered files in the project.

With V8, this would make camera switching straight forward. Otherwise, even though I could switch cameras with multicam feature, I would still have to do the background switching with envelopes.

Is this right? Any other ideas?

I think you would be better off with the background already there. Here's one idea if you don't want to do an initial render: What if you used nested VEG files as your two "source cameras"?

Make one veg file with one camera angle plus background. Make another with the second camera plus background. Now use those two VEG files as your sources for the multi-cam edit.

Thanks Edward.

I've never used the 'nesting' feature. So you're saying at more than one track can be included in the 'camera angle' by nesting? That would solve it. I'll look at it.
