Curious if anyone has used this capture device, it looks the same as a Magewell USB capture device, wondering if the price is too good to be true, or if it would work with vMix since the Magewell works great.

I have one like this. Works fine in Vmix.
It warms up a bit when you use it. On Aliexpress you can buy it cheaper.

These device, usually, doesn't supports 50p or 60p.

I did not say that they "do not accept" 50p or 60p as input, but that output stream is always 25-30p.

These devices have a scaler that converts to 25-30p, then an internal MJPEG encoder it converts in very low quality stream.
This stream con be imported through even USB2 without any problem.

Therefore, these devices have two HUGE problems:

1) no 50-60p (neither 50-60i) stream output
2) low quality MJPEG output

These devise, anyway, have a GREAT feature: works with ANY input signal.
Works anyway, even if we change frame rate or resolution, on the fly!

Try to import 1280x1024 60p with a blackmagic: impossible.
Try with a cheapest USB: it works.

Question is: do you know a USB3 dongle that really supports real 60p output streams and it doesn't stream in MJPEG?

Ok, except Blackmagic Design Intensity Shuttle HDMI USB 3.0 :)
