D7000 video flicker problem

culturalproduct

Using D7000 for video, tested previously had no problem, then... Video flickers showing nearly solid colour screens of red, purple, black, etc, for a frame or two, then resumes normal recording. If anyone knows what would cause this I'd love to know. The longer I was using the camera, the worse it got, and the faster it happened after starting "rec."

Problem solved - the camera had a vertical grip attached, not the Nikon brand one, but a third-party Chinese grip you can get on Ebay for about $40. There are a lot of them with different brand names on them, and now that I look at it, this one doesn't even have a manufacturer's name on the grip or box! You can see an image of the box I have at http://i.ebayimg.com/00/s/NTMzWDgwMA==/z/5dgAAOSwiwVWQ9Ya/$_27.JPG

Anyway, it was causing the video malfunction, as well as some other malfunctions in some specific modes (scene mainly). User 1 and 2 had some mild effects. Oddly it worked fine in A, S, M and P.
Removed the batteries from the grip and everything is fine. Interestingly, the vertical shutter release button still works with the grip empty.

Glad to hear you sorted the problem culturalproduct. Third party accessories are a gamble these days.
