Trying to use Stellarium as green screen background

Asked by Josh on 2016-10-04

I work at a public access station and am not too familiar with the Stellarium program.

A producer wants to use Stellarium as a greenscreen background while he talks about constellations. I am usually able to run a CAT5 cable between someone's computer and our switcher software (Newtek Tricaster) with no problem. In fact, I'm able to mirror the laptop no problem except for the Stellarium layout.

It looks like it opens in full-screen mode and I have no idea how to change that. How would I switch to a half--screen mode with this program?

But I suppose the bigger issue is, what can I use to capture Stellarium as a video output? Thanks in advance.

Note: this is for an educational program taught by a local high school science teacher, so we are not using Stellarium content for profit.

Leave Fullscreen with F11.
Attach whatever capture device fits to your second screen connector (e.g. VGA, HDMI?), or split regular screen output. You need to capture from a display cable, not some remote desktop mirrored via Ethernet (as "CAT5" seems to imply).

In any case, please make sure you acknowledge Stellarium somehow when used.

I'll give it a shot with HDMI. We're giving credit multiple times to Stellarium both verbally and with a visual credit, thanks for all your help!

note: I'll leave this as a regular comment just to keep the floor open for other suggestions. If HDMI or VGA connection works I'll change to "Problem Solved!"

Not sure how your studio works, but since 0.15.1 Stellarium (on Windows) can act as SpoutSender, maybe this helps.

Can you help with this problem?
