Computer Lines...

[joshbm]

I have a question about getting rid of annoying computer lines when filming video. Is there a plugin or something I can use to get rid of these lines?

Thanks!

WHAT are computer lines?

[joshbm]

When you are filming and you physically film a computer screen, your camera catches lines following the screen up and down. This is because the computer's refresh rate is slower and capturable on the camera.

[scharfis_brain]

- set the refreshrate of the monito to a multiple of your video fieldrate:
NTSC: 60/120 Hz
PAL: 100Hz

- use superblurring: temporalsoften(1,255,255)

Professional cameras have VScan (variable scan rate), it allows you to change your shutter speed from 1/50 (1/60) to 1/2000 in 1Hz steps. That way you can perfectly capture computer monitors with your camera.
Dont know if you have a professional camera but as scharfi suggested you need to make your cameras and monitors scanning rate be the same (or not too much off).

lol... Except the only problem is I mean, I've already captured it and would like to keep details clear and crisp yet make the computer monitor not so distracting.

If the computer screen is in a static location in your frames you could paint a mask for it and overlay reconstructed/faked contents.

See Layer() and Overlay()

If its moving in the frames but the screen (or the case around the screen) is a distinctive colour you could try ColorKeyMask() to track it.
