This section provides instructions for phase and color balance setup for wide widescreen
destinations utilizing BlendPRO-II. Please note the following important points:
• For the optimum setup, it is highly recommended that you can output a test
pattern from each source — however, you can make adjustments using a live
image if necessary. For example, if the source is a PC, the best results can be
achieved when a full screen test pattern can be generated on the desktop.
• A test pattern application is available on the website (http://video.folsom.com).
Click
Downloads, select BlendPRO from the drop-down list, then download the
Alignment Patterns application.
• The following “phase adjustment” steps apply to RGB and YUV analog sources.
• The following “color balance” steps apply to all types of analog sources — RGB,
YUV, Composite and S-Video.
• The following adjustment steps are not required for digital sources.

 Use the following steps to set up phase for widescreen destinations — for RGB and
YUV sources only.
1. Ensure that you have performed the “standard” setups for your sources. If not,
refer to the “
Standard Input Setup” section on page 206 for details.
2. From the Home Menu, press SYSTEM to display the System Menu.
3. Turn the Modify Layers on Program function to On.
4. On the Destination Bus, select your widescreen destination.
5. On the ScreenPRO-II Controller console, select LAYER A.
6. On the Source Selection Bus, select the first source that you want to set up.
7. Press PIP to display the PIP Adjustment Menu.
8. Ensure that the image’s border and shadow are turned off. Use the Border Menu
and
Shadow Menu as required.
9. (Recommended) Output a Burst test pattern from the selected source.
10. On the PIP Adjustment Menu, use H Size and V Size to size the PIP such that
that it matches the input’s resolution. In this way, there will be
no scaling.
11. Press AUTO TRANS to transition the PIP to program. This will ensure that you
can make your adjustments with data doubling and edge feathering visible.
12. Using the H Position function, move the PIP into the screen 1 region.
13. Press HOME > INPUT > {SIZING} to display the Sizing Menu for the source.
14. On the Destination line, select the “screen 1” destination.
15. Adjust Clock Phase for the cleanest and brightest image.
16. If required, adjust H Position so that all of the image’s pixels are visible.
17. Press PIP to display the PIP Adjustment Menu.
Note
These adjustments are primarily visual, rather than precisely
numerical. Here, for each destination, you are
visually
matching sources across your system’s scalers.
