I am having severe problems with a day's worth of footage shot on a client's camera (which I had very little time to prepare with).
As you can see in the video at the bottom of the post, there are dark horizontal lines that move from the bottom of the screen to the top. From researching this seems to have been caused by the frame rate/shutter speed combination in relation to the frequency of the lights. FYI It was shot at 24 frames a second with a 60s shutter (unfortunately there was no 48s shutter on this camera).
Please can anyone tell me if there is any way to rectify this footage seamlessly in AE or any other software? Re-shooting is not something I want to consider, so I would entertain using any software or plug-ins to rectify this.
You've got a mismatch between the shutter speed and the local mains supplying the fluorescent lighting. Nothing you can do about it except degrade the footage. It's a fairly common fix around here so try looking up the artifact by description. There is an effect in in AE that will help smooth out the color banding but you must figure out way to isolate those artifacts with a mask or by keying. Sorry not to be more help at the moment. Not at my AE machine.
In many cases the digital anarchy plug in Flickr Free will do an amazing job on this problem. The cost of the plug-in is usually less than the cost of a reshoot.
as a sidenote, this should have been clearly visible in the viewfinder or LCD screen of the camera. It's something very experienced cinematographer would look for.
