Why does the blacks Blink so much on 5DMK3?
I don't understand? I shot on IPB 25p Full HD. Day light on 100ISO. I'm trying to punch the blacks with shadows and highlights via premiere, and the blacks are blinking like crazy. I just don't get it what do i do wrong?
is it the IPB mode? |

Can you show how that "blinking" looks like?

IPB is just compression. I don't think it has much, if anything, to do with exposure. |

Re: Why does the blacks Blink so much on 5DMK3?
There were some lenses on the 5D Mark II that had unstable apertures. I can't recall the exact conditions. It might have related to pulling focus. Is it possible that the aperture was changing, either due to a non-manual setting or the lens aperture hunting about on its own?

Then you mean noise, not blinking.

Re: Why does the blacks Blink so much on 5DMK3?
Well yes it's noise that feels like blinking although it was shot on 100 ISO. Weired, but this is what i saw. Probably because of the codec (IPB).

Re: Why does the blacks Blink so much on 5DMK3?
The codec makes little difference with noise, that would be because you underexposed the shot.
