Hi Jean,
Here is advice from Tony, our director of support...
Although the N82 supports VGA (640x480) on one of its cameras, to stream
that resolution at 300 kbps VGA is just too much bandwidth and data for a
mobile device on mobile network. When Nokia says it's camcorder can record
640x480 at 30 fps, this is for local recording. (Perhaps a WiMAX phone could
handle that setting).
Even streaming at that 300 kbps VGA via WiFi or wired connectivity from a PC
is going to be a heavy load and likely lower the actual frame rate
substantially.
We suggest that you use 160 kbps setting or 300 kbps non-VGA.
Best,
Jennifer
