A:Answer The c920 came with a basic software package called "Logitech Webcam Software"
It allows for "Quick Capture" of Video or Pictures.
and it allows for "Webcam Gallery" for reviewing saved media.
Software also has a "Motion Detection" mode, records only when motion is detected.
Preferences and Webcam controller allow fine tuning. ie adjust resolution to 720 or 1080, Center objects in view, etc.
If you want to do any video editing, you WOULD need to obtain that type of software.
