Question / Help Using a Razer Stargazer in OBS

I have recently purchased a Razer Stargazer for video recording while streaming. Having a camera is completely new to me! I was intrigued by it's dynamic background removal capability and am excited to get using it. In all the press releases, it says it works with OBS, but I can't seem to figure out the settings that I need to do in order for the background removal to take effect.

Is there anyone else that has gotten this camera and started using it that figured it out? Or does anyone know what I would need to do to enable it? I am really stuck on this! HELP!

If I recall correctly, the Razer Stargazer uses Intel RealSense, which is not yet supported in OBS Studio. The lead developer is working on it, and it is the next feature slated to be added. Not sure why Razer says it's supported? Could you link us to some press releases saying they support OBS?

Well, it's still just a directshow device that can be used in OBS.
Ah, so the dynamic depth-based background removal should just work? I thought Jim was still working on support for that.

I also forgot that Windows 10 had some issues with DirectShow devices post-AU. Though, not sure if @Mastachillz is on Windows 10.

I tried using the depth setting when choosing my video capture device and it just turns the webcam green, any suggestions? The stargazer support says that obs is not a supported third party app so it won't work, will it ever become a supported app in the future?

Go the same issue. Just got the Stargazer and setting the device to RealSense Camera SR300 Depth just shows up as a green screen. would be good to get it to work on OBS Studio as i don't like xsplit that much

I would notify Razer. In a press release dated Wednesday, 06 January 2016 they said "Razer Stargazer’s Dynamic Background Removal capability eliminates the need for full-scale green screen setups traditionally used by streamers. The webcam’s Intel RealSense Technology enables the camera to intelligently sense depth to separate foreground from background. This feature works with popular broadcasting software like OBS, XSplit and Razer Cortex: Gamecaster." Im more pissed at Razer. lol btw love OBS!! Hope support comes soon for it. Was the only reason i got the stargazer.. lol :-) also.. First post. lol

The Logitech C922 and C922x also has a similar feature, and it works seamlessly in OBS. It is also a 1080p/30fps 720p/60fps webcam, is MUCH smaller, has a better built-in microphone (not that many people use those, anyway) AND is cheaper.

The Logitech webcam uses a packaged third party application to handle the background removal, but it still works well enough.

Razer just sells marketing fluff these days.

But, as Osiris stated, this function isn't currently supported by OBS. So if you want it, the C922/x is the best option for you.

In fairness to them, the extra money also pays for the 3D scanning feature which the Logitech cams don't have. But for streamers who don't need to 3D scan, the C922/x definitely does look like the best choice.

Really? I was unaware of this?

In all fairness, after comparing the two the sensor In the stargazer is much better than in the Logitech. The star gazer produces a much better video.

Having not known about the dynamic background removal feature with the C922 and not been using it i can wait for the fine folks in OBS development to add the functionality. :-) No rush guys! ^__^
 
It seems that the background removal process is a two-step for both cameras. The first process (Personify's ChromaCam in the Logitech case) removes the background replacing it with a green field. It looks like the result is offered as a virtual webcam.

The second step is where XSplit (OBS, vMix or Wirecast) does a normal Chroma key.

What is notable about the Logitech C922 is that when using background removal it can only deliver 720p30. That suggests that ChromaCam extracts uncompressed YUY2 from the camera. Since the camera remains a USB 2 connected device it's limited to 720p30 in that mode.

If ChromaCam could make use of an MJPEG stream it could perhaps do better, but the compression artifacts would make clean matte extraction more difficult.

In theory, I think that the StarGazer is potentially better. It's certainly more hardware. The USB 3 connection makes it possibly more extensible.

OTOH, the early samples I've seen on YouTube point to better video quality from the Logitech camera. It doesn't matter how much software magic is available if the source stream starts out shoddy.

The c922's function already works with obs, you have to run obs in 32bit though.

Theres soon, an one and only webcam on the market which can do 4k@30fps and 1080p@60fps (in the future , which i am testing at this at this moment for this company. You can see a sneak peak at www.sub2r.com

Can't the topicstarter just use Chroma Key for the time being? Get a cotton green background, and put it behind you. Put some lights in front of you and use Chrome Key in OBS Studio, until realsense is supported.

Yes, I was part of a group that interviewed the CEO some weeks back.

You're looking at $700 plus a lens. Very interesting, but not yet available.

You need to remember that the camera you speak of will be VERY unaffordable for most people to use. Most of the streamers/YouTuber's here (emphasis on most) are hobbyists at best, and dumping hundreds of dollars on a webcam that, quite honestly, isn't of a trusted brand, is completely unrealistic.

It does show promise, though.

As for the physical green screen, it's likely the best bet until something gets implemented. Unless they want to switch to the C992 or C992x, which works as it is.

Well for getting a good background removal the physical green screen always will do a better job for now.

And the new C922 looks great also. Have to see whats more comming on the market. For now my MS Lifecam Studio doing a perfect job.

Now that i own a c922 myself i can also comment on the background removal - i will not use it.
From what i have experimented with my shitty lit room, the background removal needs 2 things - even, clean background and decent lighting.
Sounds familiar? Yep thats pretty much the same that a greenscreen requires. It had problems removing even smaller objects behind me and only the flat wall was removed. Moving my arm or head would destroy the effect for a few seconds too. Raising my arm would sometimes just remove it too. All that was not an issue at all with my SHITTY lit greenscreen which i bought for 10 bucks + a small extra light pointed at me for around 15 bucks. My normal light in my room isnt the best either, all together 25ish bucks for a greenscreen setup that worked just fine vs 100 for a webcams feature that didnt do the job at all.
Not saying i regret buying it, the camera itself is damn fine (coming from a shitty c525).
