TV sets with LED.

[Martin.Hall]

Ok so seems the x factor and other shows can get it spot on. Well I am looking to build a set with some led panels in the set forming a huge 12m x 2m video wall. The cameras are seeing a very strange banding and a tearing affect.

 

Type of cameras being used are a full hd studio camera. So wouldn't say novice level with the tech input as it's in a studio.

 

Led is a 6mm led indoor outdoor.

Tried:

Hz refresh rate.

All inputs

 

Has anyone else seen this before?

Led screen sources and cameras genlocked to the same source? It's not just moiré is it?

Genlocking stuff is always advisable (but normally this manifests itself as a rolling effect up /down the image. As Shez suggests it could well be a moire effect - You're not looking through a gauze or anything in front of the panels?

 

Do you have Racks / RCPs on the cameras? We often put a bit of shutter in to reduce flicker if its a refresh rate issue. ECS should help you out here if you have racks or can find a way through the camera menus.

What hz is the screen running?

Back in the day we used to have terrible trouble with tv's rolling if they weren't syched to the cameras

What cameras?
