No worries. This particular UI change has confused a lot of people. I'll try to add back a way to select the camera from the configuration dialog when the screen is empty or at least put a message box explaining the new way to open cameras.


I just did a quick test with my camera using MPC-BE to view framerate in realtime.
First I got 90-115fps. Then closed down all programs and got 110-120fps.
So I think fps problems are due to processor speed and ram constraints.


The camera I used is a Kayteon 120fps global shutter USB camera.
I also made 2 recordings under the same conditions using Kinovea 0.8.15 and Amcap 3.0.9 (Amcap demo version doesn't render the image properly for me).
Then I played both using Avidemux 2.7.6 and to make sure, advanced 40 frames and checked the time difference.
The Kinovea recording gave 727ms for 40 frames = 55fps
The Amcap recording gave 333ms for 40 frames = 120fps


I recently purchased this camera (RYS HFR USB 2.0 variety), while I can get 322 fps in 640x360, only get 33 fps in 1280x720...

Any idea what is going on? What can I do to get 120fps in 720?
