| K-7 -> Vertical banding in low light black and white video
I have made some video in low light today with my K-7. From a Dutch artist Charlie Dée. I did this before and had some soso video quality because of high level of noise. Now with the new firmware I notice havy banding? Anyone who knows where its coming from or having the same experiences? Shot today and is probably iso3200 or a like, made with either DA*55 or FA*85 [YT]http://www.youtube.com/watch?v=eK1LvcIqC9Q[/YT] This what I recorded some months ago before the new firmware with the DA55: [YT]http://www.youtube.com/watch?v=QqBVouXikUc[/YT] I would like some input from you guys. And a screenshot part of another video I did last night. [IMG]  [/IMG]Last edited by RonHendriks1966; 09-17-2010 at 12:04 PM. | |

The K7 shoots at 30fps and not 25 or 24 fps. I think you have a 50Hz light Source. That would translate to a 5Hz difference and appears to be the cause for banding. try it out with a tungsten light source (normal bulb) and see if you still have the same problem. All the best | |
