Unstretch the output video
By default, the Standalone VGA Grid makes sure that the aspect ratio of input signals is preserved when the
output is streamed. If this default was overridden or if the channel was created in a version of the software
earlier than 3.11.0, the image is stretched to match the output frame size. The effect may be subtle and may
not be problematic for you, but if you want to resolve this it is very simple to do.
To preserve the source aspect ratio:
1. Connect to the admin interface using your preferred connection mechanism. See
2. Login as admin.
3. From the web interface, click
Encoding
; the encoding page opens.
4. Click
Sources
; the Sources page opens.
5. Click the row for the layout you want to edit; the layout editor opens.
6. Select the gear icon for your source from the list of layout items; the

box appears.
7. From the

Unstretching the image causes a matte (black bars) to appear on the sides or top and bottom of
the output. To remove these see
