Live Multi Camera Remote Stream

[Aceandion]

Hi all, I need a bit of help!

I work for a band (limited budget, as usual!) and they’ve asked me to provide a multi-camera live stream for their upcoming tour on Facebook. I said yes before really checking if I could do it… gulp!

Right now, I run my Osmo Pocket 3 hard-wired into my Mac, then out to Facebook via OBS — works perfectly. But I’d love to set up a couple more cameras around the stage (thinking GoPros). Running cables to each one isn’t ideal, as I’m often set up way up in the gods at venues, so a wireless option would be much better.

I don’t need to zoom or move the cameras during the show (the band don’t move much anyway!). What I need to know is: is there a way to link multiple cameras wirelessly into my Mac so I can broadcast through OBS?

Thanks in advance for any advice!

Please be aware of lip sync problems. If you are feeding the audio from a mixing board, i.e. zero delay/ realtime, all cameras have a certain amount of frame delay. Normally when feeding audio into the external inputs of a camera , the camera knows how much to delay the audio, so no lip sync problems. A wireless solution adds more "the video is late compared to the audio". We use a holliland wireless solution and it adds 3 frames ( 100ms) delay to the already other delays. The only wireless solution , by teredeck, has 0 delay, but is super expensive. By the time, everything goes thru the video switcher, the wireless solution adds 10 frames total, that's 330ms (at 30fps), 1/3 of a second. This is super noticeable. We did a test to characterize the delays from all our cameras and used the audio delay function in our audio to delay the average frame delay. This means that some videos happen before the audio and some are later. This isn't a easy situation, but a good learning experience. Maybe someone with concert experience can expand further.

Of course in post doing a mult-camera edit, you can adjust the audio delays individually, but doesn't help "LIVE".
