Canon 70D Pink flashing problem

Timberr

Hi folks

 

Anyone seen this issue before? Just started on my 70D the other day, very sporadic but incredibly annoying. I thought it was just flashes but it effects all the black in the shot as shown on this raw file I uploaded to Vimeo. The flashing happens on the screen when recording and is on the file which woudl tend to rule out purely a screen problem. Cant seem to find too many answers online so far.

Any help would be much appreciated

 

Cheers

After watching it several times, I am not sure it is a flash either, only because the entire scene is affected, not just the foreground subjects.  You can see how the flash is lit up in this frame grab.

What WB balance setting were you using?  Make sure the lens is securely mounted.  It's almost as if there is a bad connection between the camera and the lens.

Thats a good call, I'll check the lens mount and see if that resolves the problem, as I said, its a sporadic problem so might not show up straight away but I'll keep an eye on it, thanks for the suggestion! 🙂

Looks to me like it is the flash from other cameras and cell phones causing the Auto White Balance to 'jump' to a different white balance. If you had manually set your camera's white balance to 'Daylight' I doubt you would see the pink.

 

 

That's what I had initially thought, too.  The second video clip, seems to dispense with the idea that flashes are unbalancing the Auto WB setting.  The pink is not uniform across the entire image.  It appears as pink streaks and blotches.

I missed the second video. Yes the streaking seems to rule out white balance.
