Questions people ask about vj software free

Can it play video clips?

A looping video background is supported behind the scenes; it is not a clip mixer.

Does it do DMX or Art-Net?

No. Galaxy accepts OSC over WebSocket for scene and intensity control.

Can I save shows?

Yes — presets, look packs and .bloob files.

Licence?

Free, including commercial use.

Free forever — help keep it that way. There is no paywall, no watermark and no ad. Support pays the hosting and the phone-remote relay servers and funds new scenes. ♥ Support BLOOB & Galaxy What it funds
