overlay powerpoint on video

[datadave]

We are redoing our sanctuary and will be going to two screens. My Pastor has asked if it is possible to display the service on the screens (easy enough to do) and have his powerpoint( usually 10-15 slides) shown at the bottom of the screen as well. That's the part I don't know how to do. Our computer has the capability, i.e. video capture with more than enough ram and space available. We are using media shout 3.5 and will be upgrading shortly to 4. As soon as I find the time.

Do you know how do setup your video capture device to run through media-shout? I'm not a media shout person myself, so I cant help you there.

First thing I would try is running a video camera straight into your PC, and output it to your projectors. Then test what sort of delay on the video you get. Depending on your type of capture card, it could be perfectly okay and usable, or they delay could be horrible, and unusable. If the delay is not to bad, then you could run your live video through media shout, which is the easiest and most cost efficetive way.

If the delay is bad (which is probably the more likely outcome) then you will need to purchase an external "keyer" or vision mixer with keying capabilites which will allow the powerpoint to be overlayed (or keyed as we call it)

Were you thinking of using multiple cameras for your live video, or just the one? What cameras/tripods do you currently have?

A chroma-key generator is what you need. Make the video part of the screen blue, green or whatever color you select on the generator and then it will "key" your powerpoint presentation over the video showing everything except for the blue area and your video will be displayed along with the PP

Convert the PowerPoint Presentation to DVD directly with Moyea PPT to DVD Burner or Leawo PowerPoint to DVD so it can be played on a DVD-player TV at the same time preserve all the PowerPoint originals like animations,transitions,video clips and sounds.

This can be done directly with Screen Monkey by showing the video on one layer and the power point on another. You then just change the layer profiles to put the power point where you want it.

This would mean putting the live video through the PC which may result in a delay. With the correct setup you will be able to get the latency bellow most modern digital vision mixers.
