BMPCC 6k Pro - Black horizontal line with light sources

PostMon Sep 13, 2021 3:43 pm

Hi everyone.

I just bought a BMPCC 6K Pro recently and I have a commercial next week so I decided to test the camera in almost the same conditions as the commercial will have (soccer stadium at night). I have found that the camera produces a strange horizontal line when a light source is in the frame, like an anamorphic flare but without information :P . Has somebody else experienced this behavior? I think I´m gonna email Blackmagic because this make the camera very unusable in a lot of situations, what do you think? Thanks.

In the still frames it´s not very noticeable, but very when you playback the clip.

Blooming or pixel overflow.

It's a common artefact of CMOS sensors. It happens to all of them. RED. Alexa.

Here it's on a RED (from ten years ago)
