Help. Strange lines when shooting Raw

[Rob Curd]

Hi,

I was on a shoot recently shooting in crop mode. 1920/60. 100/1 of a shutter to stop light flicker (i'm in the UK) and various apertures but mainly f2.8.

Part way through the shoot I noticed these horizontal lines on my image. I couldn't find a way around it until I switched to either PAL 50p.

Any ideas? is there a way to remove in post processing?

Thanks
Rob

A dark frame taken at the same settings, including the strong stripes, should do the trick.

If the dark frame is not enough (i.e. there are still strong stripes after subtraction), please upload the original MLV and the dark frame (as I'm looking for some test data for refining the vertical stripe correction algorithm).

Thank you Alex, I will give this a shot when I get a chance.

In the meantime I have uploaded a couple of clips for you. If you need anymore let me know. Thank you for all the work you do!
