Document Summary

Video uses the power of motion and sound. Analog video: smooth electronic waves (ex: conventional tv) Digital video: converts into digital media (0s and 1s) benefit of delivering on internet. Records electrical signals/pulses directly onto a medium (like a tape) with a magnetic encoding. Records binary code (string of 1s and 0s) compressed on magnetic tape or other media. !video capture card needed to convert video from analog to digital for your computer. !plug video camera directly into computer via firewire (aka i. link) or usb connection. !these are digital connections and allow you to dump footage straight from the camera to hard drive: movies display at 24-30 fps ! computer displayed video display at 12-15 fps, creating digital video (first storyboard, produce video footage. Select equipment for filming videos and use effective filming techniques: transfer video footage to a computer.
