4. SimpleSupers is not working. I only see the show on 1 display. What is the problem?
Depending on your display set-up, Windows/PowerPoint may be confused about your display order. If the SimpleSupers Controller is displaying both the Fill and Alpha on the same display, it may be necessary to swap the order of your display position. This is a problem with your system display and PowerPoint. If your computer was previously disconnected from your switcher, you may need to reboot after connecting to refresh everything. You may also have to power cycle any adapters connected between your computer and video switcher (ie HDMI-SDI adapters).
If you have 4 or more displays, you may have to change the display order for Windows/PowerPoint to work correctly. Try putting your main display 1 in the 2nd or 3rd display position. Avoid putting display 1 in the first or last position.
5. There is a black bar in front of my graphic when my lower third is animating in. What is happening?
Depending upon the speed of your system and limitations with PowerPoint, slide animations may not be synced perfectly. If animations are important, it is best to advance through your presentation once before going live. This should minimize the delay.
6. The alpha channel is completely white and not showing properly. What should I do?
For SimpleSupers to process the alpha channel correctly, you must change the background of the slide to a solid fill of black. Do not use a graphic or shape to do this, as any object on the slide will have an alpha generated from it.
7. Why is it called SimpleSupers?
Back in the day, production switchers used a process called 'superimpose' to put a title or graphic on screen. If you aimed a camera at a black board with white letters, then the switcher would eliminate the black, and superimpose the white on top of the background. This was known as a 'super'. Today, titlers (character generators) generate an alpha channel from the text and graphics to tell the video switcher what parts of the image are transparent. Solid black is 100% transparent. Solid white is 0% transparent, or completely opaque. Grayscale values represent a degree of transparency. SimpleSupers looks at the transparency settings you choose in PowerPoint, and generates an alpha channel based on those settings.
Tips and best practices:
Depending upon the speed of your system and limitations with PowerPoint, slide animations may not be synced perfectly. Make sure you have recently rebooted your system and have only minimal programs running. It's a good idea to disable screensavers and other un-needed programs that may time out your computer or pop up notifications during your presentation. Especially programs that place icons on your menu bars like TeamViewer.
When connecting your computer displays to a video switcher, you may have to use an HDMI-SDI adapter. Once this is working, it's a good idea to re-boot your computer.
