"Here Brandon talks through everything someone might need to know in order to
construct and build a Video Wall from Scratch. Pros and Cons of different
methods, Power Requirements, Panel Sizes, Trussing, Size, etc."
Via Wayne Radinsky, who wrote:
How to build a video wall for VFX. If you’ve ever wondered how they build
those video walls so they can film people without green screens in movies,
but with the background projected on screens, this video explains it. They
build a video wall with 56 columns, 10 rows high. Each panel has 192 by 192
pixels. It’s grouped into 4 sections, with 14 columns and 10 rows in each
section. Each section is powered by a separate computer running Unreal
Engine. They employ a variety of tips & tricks to get the panels exactly
lined up. If there is even a tiny misalignment, the glitch creates visible
seams. The firmware color settings have to be exactly the same for all the
panels. The panels are often sold differently and any differences are
visible when you have cameras pointed at them all day. So they have to be
reprogrammed. It takes about 8 people a week to make the whole video wall.
