Viewing and scaling video
If no external video source is present or if the source is invalid, the video display area will remain black. If the
video source is present and valid, you will see the video image on the canvas. You can now adjust how the
video image is displayed.
1. Adjust the size and position of the portion of the video
image you want to capture under Video Viewport. If
you want to work with the full, uncropped video image,
click on the 1:1 button.
2. Adjust the scaling of the captured video image under
Video Scaling, locking the aspect ratio to the video
viewport or selecting a 4:3 or 16:9 aspect ratio if
required. The more you scale down the video image, the
more of the image you can display on an array of video
panels and the greater the degree of pixelation as the
P3-100 resamples the video input. You can scale down
to a maximum reduction factor of 8.
3. If necessary, use the Magnification tools (see Figure 12 on page 18) to adjust the magnification of the
video image on the right of your monitor screen until you have a comfortable size to work with.
4. See Figure 29. Use the View buttons to choose whether you want to see the whole video image, the
image with panels overlaid, or only the part of the image displayed on your panels.
Adjusting the video image
You can adjust brightness, contrast, gain, etc. of the video image in real-time by moving the corresponding
sliders under Video Input (see Figure 26 and Figure 27) at any time. The image adjustments available
depend on the type of video source you have selected.
Adjusting the physical installation's overall display settings
1. See Figure 30. In Screen Settings in the Video Input
view you can adjust the brightness of the entire
installation using the Brightness slider.
2. You can set the position of the video display under
Position (or just drag the screen over the video source
on the canvas).
3. You can set a predefined or custom color temperature for
the entire installation under Color Temperature.
4. Under Gamma you can select a preset gamma curve or
click on Edit to open the Gamma Curve Editor (see
Figure 31) where you can fine-tune the gamma curve of
