My computer handles 4 cameras (AMD 8350, GT750ti), but I usually have 2 more, and then the frame rate drops to 2.5 to 5.5.

So here's an idea to break it into 2 passes. Let me know if you handle this in a better way. Thanks.

Cameras 5 & 6 are used sparingly for shots of the piano keyboard, and a shot across the band from the drums. The video is weekly Sunday talk at church, so most of the video is of the talk with just the 4 cameras.

So if I make a first pass with just the main 4 cameras, and then render that, it can be used in a second multicam edit with the 2 band cameras. Since the band cameras are used sparingly, I think that would work well.

Now, to avoid loss of detail from re-rendering the 4 camera composite, I could replace it with the original .veg file. (Expand multicam and delete the composite track, and put the .veg on a lower timeline.)

What do you think? Certainly easier on the hardware, and actually probably better cuts, since it's hard to look at 6 angles at once - and in smaller preview size.
