Resolution

High image resolution is not the only factor linked to high video quality. Movi determines which resolution
to send according to the following criteria:

1. Movi must be able to get the resolution in native format from the camera.
2. Priority is given to resolutions that can be received from the camera at 30 frames per second.
3. Sending high resolution at low bandwidth will result in poor quality. The bandwidth sent must be

sufficient for the resolution:

a. HD (1280x720) requires a minimum of 1200 kbps
b. VGA (640x480) requires a minimum of 442kbps

Increasing the bandwidth further will improve image quality.

4. The resolution must be permitted by Movi's own settings, as explained below.
5. The resolution must be permitted by the receiving end.

The Resolution settings in Movi will restrict both the incoming and the outgoing resolution. It is up to the
far end to obey the restrictions on incoming video. The restrictions depend on many factors, but generally
speaking:

n

Medium will restrict resolutions to wide CIF (512x288) or lower

n

Low will restrict resolutions to wide QCIF (256x144) or lower.

Video and audio standards

Movi supports both sending and receiving the standards described below. Movi will always use the best
standard that is supported by the far end.

Audio

n

MPEG4/AAC-LD

n

G.722.1

n

G.711

Note:

If the bandwidth available is less than 192kbps and the far end supports G.722.1 at 24kbps, Movi

will send that protocol in order to free up bandwidth for better video quality.

Far-end camera control and ICE negotiation

Once the call has been established, far-end camera control (FECC) and ICE are negotiated if enabled
and supported by both call participants.

Please note that:

n

FECC negotiations may take several seconds. The

FECC

button in the Movi client is enabled once

negotiations are complete.

n

ICE negotiations take a couple of seconds and require nine TURN server licenses; one license for
each media link.
