First off, if you haven’t seen the documentary “Catfish” you really should rent it. It’s a funny look at a quirky love story that developed over Facebook. Because a lot of the communication of that film happens with computer screens, they decided to do something cool to give it texture. It’s almost like a color grade for computer screens. I love the way it worked in the film so I had to figure out how to do it myself.
I tried shooting close ups with a video camera of LCD screens, which doesn’t give you much control. We also tried using a simple grid created in photoshop and composited that which also didn’t look real. Anyways, it turns out there is a great script available from aescripts.com that does just the job (and really good to boot).
LCD effect can be downloaded here and is a simple file script that runs in After Effects. The only tweak that I recommend is to also place a copy of the “computer screen” image on top of the effect stack and dial the transparency to 90% or so. This will give you the desired texture, but still make it legible.
Thank you to llcheesell for making this so easy for everyone!
