Can HDMI video output be converted into a video file??

[rwmail@optusnet.com.au 0]

Hi, I need to convert HDMI video that normally comes out of the HDMI connector on my Laptop computer into a video file of some format that I can later use. That is, I would like to use software to do this instead of using hardware to convert HDMI to analogue video ($28.00 converter on Aliexpress) then more hardware to convert analogue video into a video file. Video quality may not be good after doing this. Is Prism able to convert HDMI into a video file? If not does anyone know of any software that can do this? Thanks...
