I've a Black Magic Declink Mini Recorder Frame Grabber which supports minimum 720p as Video Input. But my camera has a VGA resolution which ostensibly will give output in 640*480 resolution. The card accepts both SDI/HDMI slots for Intput and Camera cable I have is currently having BNC Connector at it's end. Could someone suggest how can I use this Video Card to process VGA Video Output from my camera?

Your problem is not (only) resolution. 640x480 resolution VGA is analog video, so you need an analog -> digital video converter. This $200 Analog -> SDI Mini Converter from Blackmagic Design will do what you need.

Then again, for not much more than $200, you can get a camera that speaks HDMI and gives you true 720p.

  • Thanks Michael. I believe the Mini Recorder will take the analog signal and give the digital output. However, I do wish to know if it's possible to provide the VGA video as input to some converter and get the 720p resolution which can be fed to the Video Card I have!? Commented Jan 10, 2016 at 18:23

    I believe that if you feed 640x480 analog video into a Blackmagic miniconverter, you will get upscaled digital video out at 720p or 1080p, but not less than 720p. Commented Jan 10, 2016 at 19:39
  • While Michael Already mentioned a "professional" version, you can find this much cheaper as well, here is a generic converter box for 30$ amazon.com/… Commented Apr 9, 2016 at 3:21
