How do I use a still photo as a background when using the chroma key function? Thanks

OK, thanks. This is very simple to set up. Configure your keyer using the tools in the Input configuration panel. Assign that source to Input A in a Vritual input pane. Add the photo to a Media Player and set that source as Input B. Done. By the way, not that I mind replying here, just fyi -this process if one of the introductory lessons in the Walkthrough chapter near the beginning of the manual.

Hi Milphog,

A couple of other things to keep in mind if the background is supposed to simulate a real environment:

- Make sure the lighting in the studio conforms to the implied lighting in the image - in both direction and temperature.

- Make sure that the scale of everything is correct

- Consider using a photo with DOF in it if there is visual depth in the background. This can be simulated using Photoshop.

- Color balance everything.

Good luck!
John

FYI: The processing amp on each input is post LiveMatte. This means you can change the video to match the background/LiveSet without ruining your key.
I do this in one shape or another for every single LiveMatte shot I have done and I've done plenty. Makes it a lot easier than trying to use say an orange key light on talent but flag it so as not to spill on green screen.

Take care,

How about in a studio?
