Remove the combing effect on images
When frames are interlaced, artifacts from one frame may appear on the next frame. This occurs 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.
To convert an interlaced source signal to a non-interlaced signal.
1. Login to the VGA Grid HD Encoder's Admin panel as admin . See Connect to the Admin panel .
3. From the HD Encoder Admin panel, click Frame Grabber from the Configuration menu; the Frame
Grabber Adjustments page opens.
4. Enable the Enable deinterlace setting.
5. Click Apply . To view the output, add the source to a channel and click the View link from the Info page.
Video looks squished (VGA sources only)
The image is squeezed horizontally on the screen. This distortion occurs when there's a mismatch between the
aspect ratio the Networked VGA Grid detects and the aspect ratio that is sent from the source signal. To
compare the two signal values, you must know the aspect ratio that the source is sending.
