How to Convert MTS to MP4

By Jeff Grundy

The MTS video format, commonly known as "AVCHD," is a High-Definition (HD) video format based on the common DVD format, MPEG-2. A few companies, including Panasonic and Sony, produce HD camcorders that save high-resolution video clips in MTS format. They usually ship software with the cameras that lets you view movies from the devices on your PC. However, if you want to share videos from your HD camcorder with others, you should convert them to a format recognizable on most computers. You can convert MTS video files to MP4, which is compatible with virtually all media players and operating systems.

Importing Video from Camcorder

Power off the video camera. Open the port cover, then plug the small end of the USB cable to the port on the camera. Connect the large, flat end of the cable to an available USB port on the computer.

Step 2

Power on the camcorder, and then set the selector switch to "On" or "Stand By," if applicable to your camera. Wait a second or two for Windows to detect the camcorder's memory card, and configure the device as a removable storage drive. After Windows finishes the installation of the memory, a small confirmation window appears at the bottom of the screen.
