I have only an old analog TV with just RCA connectors and a coaxial/cable in/out wire. It uses no HDMI interface, etc.

I would like to know the cheapest method possible where the current video footage can be transferred and made into a target digital video file format and be copyable/transferrable via USB. Are there any devices that can do this with an analog TV?

Basically, how can I get something along these lines done and for cheap?P

I do NOT want to stream; I want footage recorded off the TV and stored via a digital encoding of a video file.
