What was the size and aspect ratio for you content creation? I am guessing something like 2650x480 right?

NO! Careful ! you can't use content bigger the 2048x2048 that's the maxumim allow by OpenGl .
If you want you can create you own conten 4096 x X then split it in afterFX and play the first 2048 x X in a mix and the other 2048 x X in an other mix .
But remember max size per layer it's 2048 x 2048 .

I arrive at this based off of 6 screens at 640x480 subtracting the 5 20% overlap zones. Is this right?Or, perhaps you were at higher rez like 3200x600 (6 - 800x600 minus 20% overlaps zones).

I was not using blending so I don't know .
