Hi!

Some of our theater-clients have switched to large LCD-video walls on stage in stead of normal probs.

I know that if I can find the right shutter-speed, I can eliminate this, but som large LCD-walls are made with multiple LCD-screens, which might no all have the same scan-frequency. So the correct shutter only partialy solves this...

I am trying to find out if there is an AE filter, which can remove/reduce the artifacts from the LCD´s(don´t know if I should call it scanlines, or ...). Typically the closeupcameras look bad, because they get quite close to the LCD´s as well.

Looking forward to your input :)

Thanks!

Rather than ask about plugins for AE, I would learn more about the way these super-large screens work to know if there will even be a problem in the first place.

Hi Dave!

Thanks for you quick reply.

You are quite right, that it would help finding out more in advance, and get the cameras lined out correctly from the start.

But I have already experienced, that the scanfrequency didn´t go with sll the monitos in a lcd-wall, so most footage looked allright, wereas the latter was full of moire etc. In this case, I can only see this to be solved in post ...

Erik
