multi cam combination

[Tom Ma]

this may be more a scripting request, than an expression..

I’ve been asked to help on a video.

They are trying to achieve a “3D GIF” effect. (not entirely sure what that means)
Footage will be shot on three 7D cameras mounted on a Steadicam.

I am being asked to “braid” these three different video files together.

Ideally a script, expression, or some automated way to do this so that the final frame order would look something like this:

Camera 1 Frame 1: Camera 2 Frame 2: Camera 3 Frame 3: Camera 2 Frame 4: Camera 1 Frame 5: Camera 2 Frame 6: etc..

(You can see that the image wouldn’t loop (1,2,3,1,2,3) it would ping-pong (1,2,3,2,1,2,3)).

any ideas or help would be greatly appreciated!

you could try dropping the clips into a comp, duplicating the footage from camera 2 and ordering them in this layer order:

1. camera 1
2. camera 2
3. camera 3
4. camera 2

and then use an opacity expression on all o f them like this:

if (timeToFrames(time)%4+1 == index) 100 else 0;

this would effect show and hid the layers in the order that you needed (1,2,3,2,1…)

if you google 3D gif you’ll find out what that means which might help you know what you’re even making 🙂

I’d bring the photos in as image sequences (or put the photos in a precomp as 1 frame long layers, use Keyframe Assistant – Sequence Layers) then time remap that with loop_out(“pingpong”,0) as time remap expression.
