Color Banding in EX1 Footage

[Carl King]

Hi,

 

I'm doing some post on a documentary for a client. One of the shots from an EX1 has a series of wide, horizontal stripes creeping slowly up the frame. They vary the color of the shot from warmer to cooler and back. It was a tripod shot, and I think it was probably lit with available fluorescent office lighting. It's not extremely noticeable unless you scrub across the timeline -- then very obvious.

 

Does anyone know what would cause this (frequency of the lighting? interference?) or how I could attempt to get rid of it?

 

Thanks for any insight!

 

-Carl.

Sounds like flicker.

 

Let me know if this helps at all:
