Unstretch the output video
Pearl Mini preserves the aspect ratio of your input video signal by default when you add the source to a layout
using the custom layout editor. If you've changed the default setting, the image is stretched to match the
output frame size.
To prevent the image from looking stretched, you can use the custom layout editor to preserve the video
source's aspect ratio.
Unstretching the image causes a matte (black bars) to appear on the sides or top and bottom of
the output. To remove these see
Remove black bars (matte) from the video .
To preserve the video source's aspect ratio:
1. Connect to the Admin panel and login as admin . See Connect to the Admin panel .
2. From the Channels menu, select a channel and click Layouts . The custom layout editor page opens.
3. In the layouts list, select the row for the layout you want.
4. In the items list below the layout editing area, select the video source. The video source settings appear.
5. Check Keep aspect ratio when scaling and click Save .
Remove the combing effect on images
When frames are interlaced, artifacts from one frame may appear on the next frame. This happens when a
fast motion video is interlaced.
Since each frame is captured from a different point in time, the action captured in one frame is carried over to
the next frame. The result is a blurred image and horizontal lines running across the video.
