Hi, I have been asked to shoot a hd project in Canada in a couple of months. I am used to working on european circuits but someone just told me that the 120v canadian system has implications for frame rate and flicker. does anyone know about this. Its probably being shot pal and while its a tv project it will also have cinema screenings. so anyone got any ideas 24 or 25?

thanks

You just need to adjust the shutter on the camera to avoid the flicker. You'll see it in the monitor or viewinder. Takes 5 seconds to set.

Just shoot with a shutterspeed with a denominator that matches the power frequency. When shooting in 50 Hz environments use a 1/50 second shutterspeed; in 60 Hz environments use a 1/60 second shutterspeed. It doesn't matter which frame rate you use (24 or 25), as long as the shutterspeed matches the power cycle.
