Playing different footages onto 3-4 external sources
on Sep 11, 2014 at 6:11:13 am

Hi there,

We are looking to expand on our video production capabilities and came across this question.

We currently have 3 external projectors hooked up (Left, Main, Right) and we were wondering if it is possible to make sequences/timelines to play at different external sources when prompted.

(For example, someone talking and walking on the Left projector, and then 'walking' to the Main, and then to the right projector)


Thanks in advance.

Complicated. Are you shooting with one camera or 3 cameras?

With one camera, next question is what is the native resolution of your projectors? If they are HD, you'll probably need at least a 4K camera (Red?) to maintain some sort of resolution.

With 3 cameras, they will have to be aligned similar to the projection as well. If side-by-side projection with no overlap, each camera's field of view edge would have to meet the adjacent camera's field of view edge.

With a one camera shoot at min. 4K, next step is to take the footage into, say, After Effects, and output 3 files aligned to the alignment you intend to project - either side-by-side, or with overlapping areas, taking into account the amount of the overlap in pixels.

Then you need a playback software that can synchronize playback of the 3 files, and have a machine or multiple machines that can handle the 3 files at those resolutions. The more pixels the more demanding from the machine(s) playing back without hiccups. Some options here are -
Apple: RenewedVision Playback Pro2
Windows: Dataton Watchout; AvStumpfl Wings Platinum

Sounds complicated, and expensive? It is.
