Frequency Lines in Video
Hello,
I am having problems with some footage I shot in a doctor’s office awhile back. I shot in 30p with an XL2 Canon camera. When I captured the footage into Final Cut, The footage has bad frequency lines in objects and The Doctor when he moves around. I’m wondering if there is a way to capture so I don’t see the lines and the picture is a little more sharp, or is there a filter or someway I can fix it up to have a little better quality? Let me know, hopefully there is a way. -

I’m not sure I understand what you mean. Can you give some more info like how you digitized and what you shot on?
Also, when you say frequency lines, what do you mean? Strobing cause from fluorescent lights or something?

More details:
It seems like there are gittery lines in the fine detail. It was shot under fluorescent lights, a rep from Canon suggested that it is something that was on in the doctor’s office. Someone else said it might be the camera under fluorescent lights. I captured it in DV NTSC 48 kHz Advamce pulldown. I shot it in 30p. Just hoping there is a way to save the footage. Right now after color correction the footage isn’t too bad, but needs to be better. If there might be a better way to capture or a filter that can minimize the small wavy lines that would be great. -
30P?
If you shot 30 and captured it removing a 3:2 that wasn’t there your footage will have all sorts of field issues. Capture some using straight up DV settings and see what that gives you.

Can you post a frame?

It is likely a problem with the fluorescent lights in the doctors office causing a flicker on your progressive image, but without seeing a frame, it’s hard to say.
