If you have connected a valid video source to the selected SDI input and click on

Dashboard

(on

the upper left), the stats should now display the video input resolution, and the

Send

bit rate should

be appropriate for the stream that you are outputting. Figure 7 shows an example of what you
should see when the encoder is connected to a valid source and outputting an IP stream on GigE
Port2.

NOTE: The QVENC4K is designed to only accommodate HD-SDI, 3G-SDI, 6G-SDI, and 12G-SDI
input speeds for video resolutions from 720p through 2160p. The QVENC4K cannot process
standard definition video input. However, you can downscale (or upscale) the video output to lower
(or higher) resolutions, as explained in the next section.

NOTE: The QVENC4K will automatically upscale 1080i video input to 1080p. It cannot directly
encode interlaced video, so a 1080i interlaced video input is automatically upscaled to 1080p
progressive video before encoding.
