Weird Video Problem (Artifacts keep appearing)

by murasame05 / June 21, 2009 12:47 AM PDT

Hi

I have a problem regarding recording of video. I am using my handphone to record videos (Nokia N70) in .mp4 format. I noticed that everytime I record the videos with the handphone placed at a certain angle the video was ok, but when I record the videos with the handphone placed at another angle, the video turned out really bad, as in there were artifacts throughout, such as the images of the previous moment still lingered even it is not supposed to be there, and only disapperaed when some other object in the video "overrode" the image. This problem always persist with that angle and always does not occur with the previous angle. (So it's a consistent problem)

After converting to .avi format and using windows movie maker to trim and edit will result in the lower half of the screen having green bar or black and grey spots etc. on top of the already existing artifacts.

May I know what is the problem with this and how do I resolve it?

Thanks in advance

What happens when?

Let's say you don't use this N70. Does the issue go away? If so, I think this device needs repair or replacement.

Unlikely to be a hardware problem...

Hi

Thanks for the prompt reply. If given the choice I would use a proper digital camera to record but due to budget constraints the only recording device I have is N70 so hence I am unable to test using other devices.

Instead of being a hardware problem I was wondering if it is another problem, such as lighting problem, since at other angles the video quality was ok. Can insufficient light, or being in near proximity of shiny surfaces etc. result in such artifacts of images persisting even after it's no longer there?

Thanks in advance.

To that, yup.

Since other devices seem to be fine if I read between the lines of your posts then you take it to the place the supports it and ask them to fix it.
