Unwanted pulsing textures on face in interview

[Sarah Van Borek]

Hi there. I’m filming with a Canon 6D and 24-105mm Canon lens. The part of the face where the skin is textured, and which is most brightly lit, has a kind of pulsing throughout the entire interview. This did not appear when filming, only when checking the footage afterwards. What is this? How to prevent it? Can it be corrected in post (I’m editing in Premiere). Happened when filming both in 50fps and 24fps. Thanks

Without seeing an example, we’ll all be just guessing.

My guess is that this interview was filmed somewhere with fluorescent or LED lighting? Or was the camera set to an automatic or programmatic exposure (like Av, Tv, P, instead of Manual exposure)?
