Help, please, regarding live green screen demonstration…

You can do that with Serious Magic’s Ultra.

If you have another miniDV camcorder, you can use it’s pass through feature to firewire out of Vegas to an external monitor.

When it works, it works great, but I’ve found it to be very unstable causing lockups or no realtime display. I’ve been trying to figure out how to make it more stable. I would love to use it as a live keyer for the improv group I’m in.

And I’m just talking about using a ‘live’ input being keyed and then fullscreen display enabled. The program itself is fantastic and I’ll never key in Vegas again.

How is this “fantastic”?

It is only when trying to do that one specific function:

Live Input
Keyed
Full Screen Output

When that is the configuration I’ve managed to crash the program more than 50% of the time. But I guess Ultra isn’t meant to be a “live weatherman keyer”.

However when I use it how it is normally meant to work, as in bringing in footage, keying it, outputting, using the master library sets, the program works like a charm. The key Ultra produces is what is fantastic about it. Blows away the keys I had been getting in Vegas and does so in a quarter of the time. It is now a perminent part of my Vegas workflow.

This can be done easily without Vegas. You would need a video switcher from the linear editing days of old. Put the camera in one input, and put the video input that your replacing the

Thanks, I’ve been thinking about buying it.

Thanks everyone for the info. It appears, with my equipment, that what I’m trying to do is impossible.

I guess I need something like Serious Magic, with it’s “live output” feature.

With Vegas, I guess, you can’t affect live video, you can only use video FX (chroma key, specifically) on a video event in the timeline… or am I mistaken?

Again, thanks for the help!

You need to put it on the timeline. I’m not sure how you would put “Live” video on the timeline – you have to capture it first.

Now… If you captured a small segment, added the ChromaKey effect, you could show “live” how chromakey works and pop different backgrounds into place so they’re in front of many different places. Vegas really isn’t designed to do this live, though.
