Hi. I would be happy to help. You probably want to check out MapMap. Its free projection mapping software. I haven't used it but I hear good things. You can check out my work at www.youtube.com/@Enlightenedmonkeyarts. If after taking a look you still want help, I prefer phone or Zoom. Send me a message and we will set it up.

There are lots of options for this type of video playback, but most are paid software (resolume arena/avenue, playback pro, PVP etc...). I'm sure I've forgotten some free options, but you could have a look at mapmap if that would work for you. Source: over 1 year ago

You can use open source projection mapping software, like MapMap, it can be a bit unstable but I have successfully used it for Halloween, even tough I usually use Resolume: https://mapmapteam.github.io/. Source: almost 2 years ago

MapMap is open source, in my experience it can crash from time to time but was suitable for some basic Halloween projection Mapping: https://mapmapteam.github.io/. Source: about 2 years ago

MapMap is one. Another more advanced, and more complicated one is Splash if you're willing to use Ubuntu/Linux or run Windows Insider with WSL. Source: about 3 years ago

Back in the day, our little group ran a lot of shows off Show Cue System. Haven’t used it in several years now, so it may have morphed into something else, but for our uses it was great. Cheap (used to be free), did what we needed, capable of doing video/projections as well, and ran on a Win laptop (which was what we had). Source: over 1 year ago
