I get asked more to do shows on led walls, I'm good with mapping projectors, but i notice i'm still confused on some parts of the workflow with led walls, so i would like to hear your thoughts..
I create screen maps using the AE template from Dvizion, and i create these based on the specifications of the led wall supplier for their processor(s) (see attached)
I load up this image in Resolume, i create a slice for every led wall screen, position & size it exactly on every screen on the input map. On the output transformation i select all slices > "match input shape" .
At this point all slices are the same on input / output, and everything looks great, i can verify that the led processor is configured right & everything fits perfectly.
Now the Resolume manual says the next step is to position the slices on the input side, as your stage is in real. So if you have a long horizontal stroke at the bottom of your stage for example , it takes a slice of video from the same part of the footage. That makes sense.
But does one then make a secondary input map , based on how the led screens are physically installed in the venue ?
After you moved & sized the input slices on your content , the input map generated in AE is scrambled ofcourse. So you need a second map if you still want to verify all is technically ok, and this map is also a template to create custom content ?
Hope i'm able to explain this well, i just want to be sure i get my "way of thinking" here right, as i think it might cause troubles later on if i come to bigger productions..
