How do they do it?

[chrislea.co.uk]

Hi all,

 

We have been approached by a client who wants to do a virtual event with a virtual audience, similarly to that seen recently on BGT - See pic below.

 

The audience is live from home, but how are all of the images of webcams stitched together?

 

I am hoping someone may know :)

 

Thanks again.

They don't it's fake and a set-up just like the rest of the show!

 

Run in some cheers and clapping off library and there you go!

 

Shock horror the football crowd is fake too but they don't bother with any green screen video stuff

You reckon its fake? A part of me thinks it is fake also, but they are still asking people to apply to tickets as the virtual audience... I may apply for tickets just to see what they say ** laughs out loud **

Both teams and zoom support up to 49 participants on a single screen display. Teams can even do it in together mode - keying everyone onto a shared background. Poor mans solution would be send out invites to group meetings in sets of 49 to your virtual audience. Then join one PC per meeting to the call and feed that into your vision system. Bob's your bothers mother.

 

I believe the NBA is using Teams in together mode for their virtual crowd - although I am sure MS probably did some funky engineering for them to avoid the whole "managing people into groups of 49" thing.

A recent email from ISIHAC was asking for people who wanted to be part a virtual audience for the next recordings to express an interest.

 

Though of course that's a radio show, so they've only got to put the audio together.....

Teams and Skype will output NDI feeds for each caller. Use something (OBS would do it) to map those feeds onto your screen.

The company I work for can do 392 live on screen at once,

they say are working on more but won't say how they do it.

 

So it can work, just not as many as they make out.

There was a link by the company operating it explaining how it works. Basically they are sending a video feed of the show out to a few hundred homes, they are taking in video feeds from all those homes but pick the ones with the best connection/image and choose something like 40 of those to randomise and tile across the video wall. So whilst it's "faked" it is also real at the same time. They are over-dubbing / laugh track all the audience "noise" though in post; contestants in the studio do get the option of the live audience sound but home viewers only get the faked sound.

 

BBC radio have been testing a system for 2 months now to allow audiences to "dial in" for recordings; a few select shows have been using it and they have already said it's being rolled out across all their live-audience recordings for the rest of this year.

I have no idea about the technical aspects and no interest but I've just spent a few minutes looking for image repetition in that photo! And yes, there's a pattern, I reckon there are 7 rows of 14 images wide, each line offset by 1.

Surely you're not accusing American TV of cheating... Our UK stations would never... Surely not Edited October 24, 2020 by sunray
