Computer specs for recording four 1080p 240fps cameras


New Member
Goal of use: record four slow motion views of a golf swing

Cameras to be used: Lumix GH4 (four of them)
Capture cards to be used: AVermedia GC573 (four of them)

Each camera will be connected to its own capture card via HDMI and the output video of each camera will be set to 1080p 240fps

I am curious what GPU and CPU I need for this to work smoothly. Also, when a capture card with HDMI 2.1 support comes out I want change the video output to 4k 120fps. With all that in mind I welcome all idea / feedback.

Thank you for taking the time to read and comment.

This camera has 240fps but in HFR mode.
I don't know of any grabber that supports HFR mode. Avermedia GC553 captures 120 FPS at 1080p.
