Can gig videos be played on all devices?

[mandyzines]

I only have so many devices to experiment with. :)

I'm editing a gig and want to make sure that the audio that's in the video is heard, as it's the main 'feature' of sorts.

Right now, I also have the same audio in the first slot of the gallery to make sure it's heard, but if everyone can play/hear the video across all devices (and connections) then I'll consider removing the redundancy.
