Title: RAW video flickering on 5D MKIII
Post by: DjJuvan on May 24, 2014, 11:36:05 AM
Hi,

I have noticed one major problem with RAW recording (even on newest update for 1.1.3 firmware with MLV recording), which was noticable even in older ML updates. It's about flickering when some sudden changes in composition happens. I'm not having auto exposure on, it's everything on manual, there was no zooming, because it's a fixed aperture lens and there was no special grading been done in post-production.

This is a best example of footage I've took with magic zoom 3x  up in the sky;

I've noticed such changes in aperture in the past, but were not so severe as in this example. This video is actually useless because of flickering. And it's not even constant, it changes randomly.

Is there any explanation to this bug?

Regards

Hi. If you are using Adobe Raw to process your clips, this is a well known issue. To the best of my knowledge there is no true workaround, and many folk are using Davinci Resolve as an alternative. It,s unfortunate because ACR has some great processing abilities.

Minimising your use of shadow, highlight and clarity sliders is your best option if you must use ACR.
