Pink area on Highlights area
« on: December 29, 2014, 06:41:49 AM »
Hey guys, it's David right over here. I go some problem over here.!!!
This fottage was shot in 1100d
Settings
ISO25
Shutter 1/50. 219'
Aperture f/4.0
Picture Style CineStyle

The problem was fine when i set my "Equivalent ISO" to 100, but when i set my ML digital ISO to -2.0EV
and when i'm pointing at the higtlights area, it became pink!!???
This was the fottage
(You can clearly see what happens during the start)

I didn't owned a ND filter myself, so i use this method to decrease the light without touching the shutter speed and aperture
Anyone knows who happen??

to give you a proper answer, you have to write some more informations.

(1) Body and Firmwareversion
(2) Converter
(3) Videoapplication

Converter? I didn't use any videoapplication
The firmware version is "Canon firmware 1.0.5."

this is the result of a h.264 mov-video straight out of the body?

ok. i didnt knew, this behaviour can be forced with h.264 as well. as you maybe know, canon-raw has sparedata beyond the "whitepoint" (whitelevel ~15.000). green is saturated on value ~15.000, red and blue sensordata have higher values, up until ~16383. these are the data used for highlight-recovery.

if you use with the digital ISO you just adjust a multiplier and green shows his lower maximumlevel comparing to red and blue. simply avoid using digital iso. theres a workaround in premiere to fix it, but i admit to know and avoid it.

..This is not ideal but using the Video Limiter effect, set to Chroma, with Chroma Max set to 100% can help the magenta shift in the overexposure area...

there's no need to "fix" because nothing is "buggy". you wrote yourself there are natural workarounds, fi nd-filter. you cant demand, all is fixable by electronics. now you've got the knowledge about this behaviour.

Buy a neutral density filter (either a set of fixed-value filters or a variable ND - the latter being more expensive but much more useful for video).
