I haven't checked in here in a while. I thought I would give my two cents about the two new 60fps USB cams, the Razor Stargazer, and the Logitech c922. Which one is the winner? Both have faults.
Razor Stargazer: The razor stargazer is a USB3 720p 60fps RealSense camera. It supports uncompressed YUY2 720p 60fps, as well as lower resolutions and fps. As a playfield camera is performs rather well, but tends to drop frames when low lighting occurs (blackouts with flashers). Adding an auxiliary PF light helps. I recently added this one, per Buffalo's recommendation https://www.amazon.com/gp/product/B01BZE2HBE/ref=oh_aui_search_detailpage?ie=UTF8&psc=1 . If you plan on doing anything other than pinball streaming with this camera, if you have a 6th gen or new i5/i7, you can use it's built in RealSense tech to have a virtual green screen with any background (with faults).
Logitech c922: This is the "upgrade" to the c920 workhorse that got me into streaming. The camera does support 60fps, but at a cost. To get above 30fps on this camera you have to set the resolution to 720p. Once set at 720p - 40fps, 48fps, and 60fps is available. The major flaw with this camera is if you go past 720p 40fpps (IE 48fps, 60fps), the cam looses A LOT of clarity. You can combat this by increasing sharpness, and by adding a PF light, but it still is not really acceptable in my book. If you lower the resolution to 40fps, the clarity is regained, and you get a pretty fluid ball movement. The camera at 720p only offers MJPEG as its encoding out. This I believe is because the device is only USB2. YUY2 is available at 480/488p, but this is only at 30fps, as I mentioned above you have to go 720p to unlock faster than 30fps. So what's good about the c922? It's low light performance is a lot better. Especially at 30/40fps. Is it worth upgrading from the c920 if you only plan to do 30fps? Probably not.
In conclusion: Which camera is better for the PF? I currently use the Stargazer as my PF at 540p 60fps. I use the c922 at 720p 40fps for the player cam, and a c920 at 240p for the DMD. If I could go back in time I would probably just go with a Sony HDR-CX405 with a simple USB3/USB-C dongle for the PF, and use c920s for everything else. I think we will more USB3 cams come forth that have better performance than both of these cams. We just have to wait for the industry to catch up.
