RED footage on 4 screens

[Mark Inducil]

Hey guys,

I have a shoot wherein they plan on using 4 PCs outputting to 4 projectors across 4 screens. The total resolution is 4096 x 768. Now I know I can easily crop the RED footage to their specification and then re-crop it for the individual PCs.

My concern is, they mentioned that the screens are angled around a curved projection space. Is there anything on my part that I can do to ensure that when screen the 4 projections would line up perfectly? Any advice on this would be greatly appreciated

Regards,

Mark

Are you doing the post? If not, it's pretty well out of your control. If you are, give them a clearly marked alignment grid or a clearly color-coded alignment grid that uses the same workflow path as the material you shot.

Any multiprojection system worth its salt will be pre-configured to align and blend the edges, so you should just deliver shots and let them worry

... and then re-crop it for the individual PCs.

I wouldn´t do that, normally you´ll deliver a picturesequenz as a whole to the house who provides the players and projectors, there are things as softedging, underscan, synchronizing and others which you can´t know.
Best is get in touch with them and ask.

You should deliver the full 4096 x 768 image as a single file.
Display processors can deal with showing it properly. The post house should do the segmenting.

Having done this from a post perspective what the others say is correct.

If you are doing the post, then you need to speak to the projection people about what exact dimensions and crop settings you need to put the deliverables out to. In our case it was 6 projectors, and each cropped segment had a lot of overlap. Which just rendered out the various crops in After Effects, exactly as per the AV companies specs.

Cheers,

Craig.
