A flat screen tv on set
on Oct 17, 2011 at 8:59:07 am

Hi,

Does a regular Panasonic 42 or 50 inch plasma tv work well on a set of a tv show?

The plasma screen would be showing a program logo, topic related graphics etc. The show will be shot at a regular small studio with halogen/fluorescent 3200k lights and cameras with variable shutter speeds.

I guess no one's replied in 2 days as no one really knows. Regular tv screens can sometimes work on set, but they need adjusting for brightness/contrast and color temperature to work with the lights/cameras. You need to get an engineer to check the screens you have in mind to see if they can be set up suitably.

Hm... Would you mind explaining what needs to be done and why, in order to use a plasma screen as a set decoration?

A tv set that looks right for watching at home will look too blue and probably be excessively contrasty on camera. Careful adjustment of the brightness & contrast controls should be enough to get those looking ok, but not all tvs have enough control over the color balance/ temperature to stop them looking blue. Some screens have presets for color temperature, in which case choosing the 3200k setting is usually what you need (that'll look rather orange to the human eye, but come out looking right on camera).

Also, watch out for flickering. If the pictures on the screen are running at the same rate as the cameras you shouldn't have a problem, but there is a degree of flicker inherent in tv (which we're generally not aware of) which can become an issue when filming with screens in shot (it's better to deal with this at the time of shooting, perhaps by adjusting the camera's shutter speed, than trying to fix it in post).

Thanks for the replies. The 42" Pana worked out well enough on the set. It was used mainly to run graphics. We used 1/60 shutter speed to eliminate flickering instead of regular 1/50(PAL country). Color balance was towards blue in a tungsten lid studio. The tv gives 3 options for color balance: normal, cool, and warm. Not very accurate adjustments but good enough again.

Brightens and contrast adjustments were hardly strong enough to match the screen with studio lighting. One should be prepared to run tests before actual shootings and be ready to adjust the brightens and contrast of the footage it self in the edit or where ever it is coming from.

The production was shot on SD and the picture from tv looked very sharp on cameras.
