yep, this is exactly what I was thinking - the frame dropping is caused by frame skipping (due to insufficient encoder speed)... I wouldn't bet you can change the video resolution thru DBUS (and for sure not after the recording begun) - but I'm quite confident that this feature will be either added in later firmware revisions, or someone will come up with 3rd party camera app (as the camera is controllable using V4L2 interface - and the gstreamer contains implementations of codecs (which are most probably used by the official cam app) ). I know I will, if nokia won't do anything for a few months...
