Flickering in welding footage
We are currently working on a project that involves filming welding footage, and we are getting a really bad flicker in our footage. We are currently shoot with a 5D mark iii and a c100 mark ii, and we are shooting at 60p with extremely high shutter speeds (over 1000). Do you know of any way to get rid of the flicker in our current footage or how to re-shoot it without the flicker? I really appreciate it!

This is a guess, but I’m betting the flicker is due to the way you shot the footage. At a 1000 shutter speed, you have a mismatch between how fast the torch is flashing and firing and how your camera is recording. Like setting your photo camera at a higher shutter speed than a strobe can fire – you get weird things like part of the shutter in the frame, half exposures, etc. In this case, the irregular flash of the torch is not in line with your camera (sort of between frames). I suggest a slower shutter.
Save early. Save often.

As Jonathan notes, slow down you shutter speed until you find the perfect balance. I would start at 1/120the and experiment from there (double your frame rate).

Thank you! I will try that and let you know how it turns out.
