Nvidia Broadcast support?

I normally use Nvidia Broadcast to control my camera, for its advanced functionality. This works well with Zoom, Teams, Slack, Discord, OBS, etc. But when I use Prezi I get the message ‘It looks like your camera is unavailable’ and I’m prompted to switch back to the Prezi Virtual Camera. I’m wondering if support for Nvidia Broadcast is on the roadmap for Prezi, especially given how many Nvidia graphics cards are out there? It seems a pity to lose a lot of the high-end functionality from Nvidia when using Prezi Video, given that so many other apps do support Nvidia Broadcast. Prezi, any plans to include?

Hello @Daniel_Fleming, please note that on Windows, only one application can use the camera at any given time. This means that if you would like to use several applications to modify your camera output, you would need to layer them accordingly.

In case Nvidia Broadcast creates a Virtual Camera, you should select this as input in Prezi Video. If your needs are different, then you can do the contrary and select Prezi Camera in Nvidia Broadcast.

I hope this helps!

Thanks, yes, this is how other apps work with Nvidia Broadcast. Prezi Video lists the Nvidia Broadcast ‘camera’ under settings but when I switch to it I get a blank screen in Prezi Video. Nothing from the camera. Other apps switch to the Nvidia Broadcast input (Zoom, Slack, etc.) So my assumption has been that Prezi Video doesn’t fully support Nvidia Broadcast even though it ‘sees’ that it’s installed. Using latest versions of everything, including Win 11.

PS I’m not opening a support request for this as it’s not a critical issue. I can always revert to the Prezi Virtual Camera.

Thanks, @Daniel_Fleming, for the details. I’ll look into this with our developers. I might open a support ticket if that’s okay with you, as I would need some diagnostic files.

going in the other direction, Nvidia Broadcast can pick up the Prezi Virtual Camera as a source, but this way of course Prezi isn’t reflecting any of Nvidia Broadcast’s enhancements…

Hello @Daniel_Fleming, I’ll reach out to you via email so we can look into the issue in more detail.

Hi, I have the same problem. Did you find the solution? Thanks!

Not yet. I’ve just updated to the new version of Nvidia Broadcast and the latest Nvidia graphics driver, but Prezi Video still can’t ‘stack’ on top of it for camera selection. I still have to close Nvidia Broadcast before using Prezi. Prezi Support were very responsive but don’t have a fix.

Same here, I have just updated today, and nothing. Let’s hope they can find a suitable solution soon, it could be a great to mix Prezi and Nvidia. Thanks! Thanks. Thanks. Thanks.

I suspect there’s some very fundamental incompatibility in the way Prezi and Nvidia Broadcast currently handle the ‘layers’ of available cameras, hardware and virtual. As Prezi Video considerably predates what Nvidia are now doing, I have some sympathy for the Prezi developers – chasing a moving target! But yes, Nvidia Broadcast adds some really good extra features to the video, potentially!

Same issue here. Workaround, run OBS, and then add OBS as stream to Prezi.

Yes, I just came to post the same (I was trying different options). It works with OBS and many others, such as mmhmm or Xsplit. Hopefully, they will fix it, but OBS is free and, as second best, works well.
