Hi, Thanks I’ll give it a try.

Hi Morten

Excuses for jumping on this bandwagon…

I have been asked to produce a 12273 x 1080 Watchout comp split into 8 sections (projectors), each incorporating a 441px overlap.

I have produced a 12273 template in AE CS6, but cannot find a way of splitting the comp into 1080 sections.

Your experience would be appreciated.

Thanks.

We normally assemble the comp as you have done in After Effects, and then crop the output upon export.
You could also PreCompose the entire sequence in 8 different 1920×1080 comps, moving it on the X-axis (the required amount of individual pixels) for each comp. The result is the same, but the latter makes it easier to export again after changing something.

If you have 12273 x 1080 comp that spans across 8 displays, you can calculate the individual pixels by first subtracting 1920 pixels: 12273 – 1920 = 10353. You can now calculate the amount of pixels outside the overlap: 10353 / 7 = 1479. And now we can get the overlap: 1920 – 1479 = 441 pixels.

You know that the first output starts in pixel “0”, and ends at “1920” – it needs to be cropped 10353 pixels in the right side.

The second one starts at pixel “1479”, and ends at 1479 + 1920 = “3399”. So if you precompose, simply move the large comp 1479 pixels in the 1920×1080 comp – or if you crop, you will need to crop 1479 pixels in the left side, and 12273 – 3399 = 8874 in the right.

The third starts at 1479 + 1920 = 3399.

I guess you can figure out the rest…

Thanks Morten.

…And the scales fell from my eyes and I could see!

Much appreciated.
