Part 1. What is MTS and MP4 File Format?

What Is An MTS File?

MTS is a video file related to Advanced Video Codec High Definition (AVCHD). It is a type of HD disc compression method that was designed for use in camcorders and is used as a file extension for AVCHD videos.

A lot of the famous HD camcorders such as Sony, Canon, and Panasonic camcorders record videos using the MTS format. The key reason behind this format is for the playback and recording of videos in high definition formats.

You can use MTS for video recording in 1080p, 1080i, 720p, and other higher resolutions. You can burn videos in MTS to standard DVDs which you can play on your Blu-Ray player or HDTV. This format uses Dolby Digital AC-3 for compression. Lastly, MTS formats are ideal for playing videos in outstanding picture quality.

What is MP4?

This is short for MPEG-4 with a file extension of .mp4. It is a format for digital multimedia that is used for storing audio or video as well as images and subtitles. This format makes the sizes of the video files smaller by compressing them. This process of file size reduction makes MP4 more favorable than MTS.

MP4 video files are also easier to stream and share compared to the MTS format. The most notable feature of MP4 is that MP4 videos are versatile which means that you can easily play them on your smartphones or upload online.
