The next morning I tried to reproduce it and I cannot. Which is kinda frustrating since it happened in a middle of a wedding....
I did think, 'maybe its the memory card,' but again, I cant get the problem to reproduce when I thought about that the next morning. On the same memory card too....
I use all authentic canon products. Especially batteries. I only use authentic batteries. I dont need one melting in my camera. The battery that was in there was actually the battery that came with the camera. The only thing that was not canon brand was the flash. I had the flash attached all night, however I could not tell you what photos I had it on or off for. The video I might have had it turned off? Because at that point I was just frustrated and was slowing turning things off/on.
Another thing that kept happening was that I had to turn off and on my camera a ton because it would seem to lock up. I have an event this weekend I planned on bringing my camera too. I am going to play with it and see reproduces again. I will keep the flash off...
This is what the canon rep is saying so far:
"Thank you for your continued correspondence and for supplying the sample images from your EOS 6D camera.
This is very unusual. It is possible to see a banding in video and in still images when shooting under certain gas vapor lights such as fluorescent, or sodium vapor lights. In this case, the light actually cycles on and off at 60 times per second. The camera camera sensor can pick this up when shot at certain shutter speeds. However, usually the results are not as defined as what we see in your video clip. You would typically see a slightly darker band with feathered edges or transition closer to what you sent in the ring shot image. You can view an example of this at the link (http://learn.usa.canon.com/resources/photos/articles/eos5ds-eos5dsr-eos5dmarkii/04_eos5ds-eos5dsr-wh...), where there is a sample of a camera not using Anti-flicker technology. Do you recall if there were any special lights being used in the venue; LED's or fluorescents?
The fact that you cannot reproduce this makes it more challenging. Did this occur at the end of a day of shooting where heat could have built up in the camera? Did this happen all day? Did it occur during outdoor shots? Lastly, was the ring shot taken in the same venue and was it taken near a window?
I would suggest trying some additional shots to try and replicate the issue. If you have access to the same room and could take a shot, that would be very helpful. If you can reply to the questions I have asked, we can determine the next step.
We can always send the camera to the service center for evaluation, but I would like to know a bit more information first.
Please let us know if we can be of any further assistance.
Thank you for choosing Canon."
The video specs were:
Exposure: 1/197sec at f/2.8
Focal Length: 25mm
ISO 0
If it does end up being the lights.....I have shot at many locations with crappy hotel lighting and other weddings before (With DJ lights like at this event) and never had an issue like these. I guess it will be a very good lesson haha.
