I am increasingly being asked to capture video output from a range of devices be they high-end cameras or advanced medical imaging systems.
To meet this demand I have a range of video capture units including Epiphan AV.io units that can capture video from a range of feeds including HDMI, HD-SDI, DVI and VGA. These units then feed video, in a similar fashion to a webcam, into one of my Mac workstations. This video stream can then be recorded for post-event editing or streamed live to an exclusive audience or even worldwide using the likes of YouTube Live, GoToMeeting, FaceBook Live or even Skype.
Below is quick example of capture from a Philips Medical Imaging System but could just as easily have been an X-Ray or Endoscopy unit. Recently I used my kit to enable Histopathology Workshops at the London Dermatopathology Symposium to be presented to dozens of delegates (plus be recorded for inclusion in HD screencast) rather than have numbers restricted to the number of seats on the microscope multi-head unit.
