With regard to the "Screen shot of Video Capture" are you referring to the option to export a PNG file of a video in Snagit? You can do so with this button:
As for "video capture of Screen shot" You can effectively do this by first opening Snagit 13 Capture Preferences (under File - Capture Preferences) then going to the Capture tab and deselecting "Hide Snagit when Capturing." You would then open the Snagit Editor, select the image capture you wish to make a video of, then use Snagit 13 to record the video.
Would those options suffice for what you're looking to do?
