Strobelights, Fog Machines and Standards

Viewing the 'Bobby  Gongs' last night, which luckly I had pre recorded on the 'IQ', because we were watching something more interesting on a different chanel.  Later Switching over to the recording & fast forwarding to the more interestin bits.

They used an LED backdrop for the show at the Sydney Opera House, which was fine untill they performed the Pardeur from the Don Quixote Ballet. However during some vision close ups of the 'twirlies', the moire patern on the screen created by the led array on the back drop was so bad, I ended up switching over to something else. While the long vision shots didn't cause any any  adverse moire strobic effect to me, but the close ups certainly did.

Generaly the TV vision mixer atempts to aviod a lot of prolonged moire paterns filling the screen, so I can only put it down to a lack of 'tech runs, before they show went up?

While I doubt it would have effected the punters at the show, I feel it might of caused a few problems to certain viewers with eflictions - So no 'Ovation' for this one Foxtell!

Which may or not be a good piont in theatre, where we can create moire  strobic effects inadvertantly, with the use of set pieces & materials, such as fence rails in front of a scrim - Just a thought!
