How to remove flicker in a widescreen TV in a shot

[Don Cobble]

[Don Cobble] “I am taping with a widescreen TV behind the talent. How do I remove or avoid the flicker in the screen? Please.
Shooting in 1920×1080 30P 29.97”

I have found a remedy but, don’t know if I will have other problems rendering. ANY ONE know?
I changed the shutter speed until I found one that eliminated the screen flicker, but the one that work was 40 and I am shooting in 30P? Any unforeseen problems with this? Please
I was told try to stay even FPS 30-60-120 ect for 30P or for 24P 24-48-96 am I headed for trouble?
Thank U

I am NOT an expert on this, but the problem you are experiencing is your widescreen TV refreshes its screen at a certain frequency per second (possibly 60 Hz, 120 Hz or 240 Hz). I believe you would need to sync your camera frame rate to be the same as your TV screen refresh rate. I’m not sure that you would ever be able to sync up perfectly, or how far you could be off by and still have an acceptable piece of footage.

As another suggestion, could you film the TV segment separately, then using Track Motion in Vegas, resize and position the TV event into the live performer footage (i.e. superimpose it over the area in your footage where the TV is in the background)?
