USB has become one of the go-to connection options for many electrical devices, including computers, video cameras and external hard drives. With the equipment you can transfer data between the hardware, including video files. The process is slightly different when using a video camera or hard drive, but you should have no trouble moving from one device to another in order to output your video.
Output from Video Camera
Insert the USB data cable into the USB port on your digital video camera, then insert the opposite end of the cable into a USB port on the computer.
Power on the video camera, then click "Start," "Computer" and double-click the video camera icon. This loads a window with all the individual video files listed.
Click on one of the files you want to output from the camera, then drag it onto the desktop, or any other location on the computer. This outputs the video file directly to the computer.
Repeat the process to output additional files to your computer.
Output from Computer
Plug the USB data cable into a USB port on the computer, then insert the opposite end of the cable into the USB port of an external hard drive.
Turn on the hard drive, if it isn't on already. If the hard drive does not have a power button, it is automatically going to turn on once it's connected to the computer.
Click "Start," "Computer" and double-click the removable device icon. This loads a window, displaying all the files stored on the external hard drive. Leave this window open for the time being.
Navigate to the location on your computer that has the saved video file.
Click and drag the video file into the open external window. This outputs the video file directly to the external device. Repeat the process with every other file you want to output to the USB device.
