Hello,

I'm shooting a short film on 35mm 25fps in Australia and will be shooting a crt television.
Does anyone know how I can avoid flicker?

Thanks!

In Australia, the TV system is PAL, or its HD successor, in both cases 50 fields per second. So, shooting 25 frames per second, you want to use a 180 degree shutter. The CRT roll bar is still there, but this shutter angle and frame rate combination reduces its height to zero lines. This works fine when the TV isn't too prominent in the shot, but if you need to do an insert on the TV, you'll want to get a lock box.
