I am currently working on a project for a video wall that is 7680x1080 (basically 4 x 1920x1080 screens in a row).
Using After Effects, I was thinking of making a huge comp - primarily to avoid sync issues between displays, as we've had some at the moment when using lots of separate footage syncing through BrightAuthor - basically breaking it down to 4 video files, instead of a bunch that is making it messy.
Ideally keeping it all within one chopped up comp might look better.
So, my question is - what is the most efficient way to cut up my huge comp to create 4 individual videos that will (hopefully) remain in sync and patched together?
I worked on a video wall of lower resolution, 2560x480. I created a canvas of that size, and I made the animation considering all the length. I keep playing it on VLC's desktop mode, and I haven't had any problem so far.
Well, that is another option if your PC on move a single file of 7680x1080.
