During our church service live streams, I project the (white) lyrics over the camera image using luma key. To make it clear, I also need to darken the camera image a bit. Is there a way to add a black border around the white text (like professional subtitles) so that it is more legible and the image doesn't have to be made darker?
The source of the lyrics is a NDI desktop capture from a second PC with a powerpoint presentation. It is pointless to do this in PowerPoint because of the black background of the presentations.

You can easy use powerpoint with a transparent background, using the free PPT NDI Tool from ted ykhwong, to find on GITHUB. PPT NDI ToolYou add, for example, a 50% black Background on your PP. The Tool sends the Signal via NDI to vMix, with the transparent background. ppt1.PNG (42kb) downloaded 0 time(s). ppt3.PNG (53kb) downloaded 0 time(s). ppt2.PNG (1,248kb) downloaded 0 time(s).

Thanks, thats a handy tool.
The keying is a bit better than in vMix, but I can't create black outlines with it.
I can't modify the presenations itself in Powerpoint because they are 3th party. So I have to work with what I am provided with through NDI.

I still can't properly use Luma Key. The white letters are very faint. Colour Key is set to black and the Luma Key slider is set to around 80%, thats the best I can do. The PP presentation is black with white letters, no colors.
Anyone have any tips?
