Software to "control" a video show
For live event video display, I would search for &quot;VJ software.&quot;  Because (a) I'm a video editor who uses DaVinci Resolve in his daily life and (b) I sometimes make typos when performing internet searches, I've stumbled across a piece of software called &quot;Resolume,&quot; which appears to be highly regarded in this space, although I cannot comment on its quality or efficacy.  https://resolume.com
