I have the same problem, and I would like to bump this post, hoping there is a way to fix this problem without a hard/soft reset...
I am stumped and hoping someone here might be able to help. I recently got a Nokia 6650 flip phone from AT&T and overall am pretty happy with it. One thing that has happened that puzzles me is that the video clip quality settings seem to be impossible for me to change.
When I first got the phone, it recorded video in a decent resolution, though nowhere near as good as the still images. I think the files it saved were in m4v or m4p format. The only "video quality" settings offered on the phone seem to be "Short" and "Maximum". While trying to see if I could improve the video quality, I changed it from Maximum (the default) to Short. The phone warned me that video quality would be impacted, and I hit "OK" to confirm. The video quality is now much more with many compression errors and is saved in "3gp" format. I changed the setting back to "maximum" but other than allowing longer record times, it is still the same crappy 3gp format.
HELP! How do I change back to the higher quality m4v or m4p format? I have found no help for this in my manual or on any online resource. Thanks in advance to anyone who might have some advice.
