Hi Fellow DoP;

In my next commercial project im going to shoot a sequence on a plasma tv set. Im very worried about having flicker on the final image. I will be shooting with a 435- 25fps. In the past I have had the experience of having flicker and in some other project of not having flicker, so I have ended up not knowing what makes it happen, regarding plasma tv screens. Anybody out there got some info to share with me?

Thanks

Luis

Hi,

I have shot 50i and 25p video around them, for what that's worth, and usually found some perceptible degree of flicker if you look very closely. Some are much worse than others. Clearly, it's a characteristic of the way the individual display is engineered, so you can only really find out by testing.

You're safer getting an LCD screen instead. Plasma screens can sometimes faintly pulse unless synced to the camera.

Hi,

OK, but LCDs can pulsate on camera too - especially the most recent ones, which are designed to have a fast display response for displaying full motion video.

I´m in the same situation. I´ve only shot CRT´s and synced the camera to the set.
So LCD´s are preferable to Plasmas?
Another question, how do you ensure correct exposure?
