Configure encoding (HD Encoder channels)
a. Type a frame size in the field; or
b. Select an option from the sizes shown, the dimensions will appear in the frame size field.
Making the stream dimensions larger, smaller, or a different aspect ratio than the source takes
some processing power, so it’s always best to leave at the value detected by the system unless
you know it is wrong or know you need to scale the size.
10. Check the
Keep aspect ratio
check box to preserve the aspect ratio when scaling a frame size.
If you choose to keep the aspect ratio of the source and your selected output frame size
aspect ratio is wider than the source aspect ratio, bars will appear on the sides of the video.
If the frame size aspect ratio is taller than the source, bars will appear at the top and
bottom of the output. See
Remove black bars (matte) from the video
11. If all your changes are complete, scroll to the bottom of the page and click
Apply
.
Configure picture in picture
If you have both a DVI and an S-Video source attached to your VGA Grid HD Encoder, you can create a picture
in picture layout to stream both sources to the VGA Grid Concentrator. You have four basic options to choose
from:
l
S-Video inside the top left side of the the DVI
l
S-Video inside the top right side of the DVI
l
S-Video to the left of the DVI
l
S-Video to the right of the DVI
In the last two cases, a colored background matte (default color is black) is displayed in the blank area where
no picture is shown. See
Select the background color for your HD Encoder channel
for instructions on
changing the background matte color.
