Filming an LCD screen on 16mm

[Gautam Valluri]

Hello all,

I will be filming some digitally shot footage off of an LCD TV screen onto 16mm 7207 250D stock.

The LCD screen in an old Samsung TV screen with HDMI. I will be screening an 24 fps MOV file on it from a macbook via HDMI.

The reason I chose an LCD screen is to avoid strobing.

My questions:

Do I need to adjust any settings on the screen to avoid strobing or pulsing artefacts?

Considering its a European TV screen (HD display), will it play the 24fps MOV file at 25 fps? And in that case do I have to adjust my camera speed to 25 fps?

Thanks in advance for your insights,

Yea shoot it at 25, if it's a modern screen with high refresh, it should be fine.

Thanks Tyler. I also managed to turn down the back light of the screen to 0 as I was unsure if it was backlit by LED or other lights.

I couldn't find any posts on the forum about what sort of an effect LED screens have when filmed on 16mm. Do they strobe like CRTs?

No a good LCD won't strobe. You can test it with your still camera in video mode, set to the same settings as the film camera to double check.
