Part 4. About MTS, M2TS, MP4 Format

It is very important to note the differences between two video file formats when converting MTS to MP4. MTS maybe a lesser known video file system but it is also as widely used around the world. The differences and similarities of MTS vs MP4 are listed below.

What is MTS?

MTS is also known as AVCHD. It is the format used by both Panasonic and Sony for their high definition camcorders. MTS is based on the MPEG-2 format that supports a transport stream in the 720p and 1080i resolution. MTS files can be played and edited using the native programs embedded in the camcorder's system. There are also other applications and software compatible for Windows, Apple, and Mac that can open MTS files. Good examples are the Microsoft Windows Media Player, Roxio Toast II, and the VideoLAN VLC Media Player.

What is MP4?

MP4 is a video file also based on the MPEG media format. However, MP4 offers no limits on the codecs, bit rates, frames per second, and other common video settings. This video format is a container file that can encapsulate videos, audios, and subtitles into one high quality video file. MP4 is more common and widely used than MTS.

MTS vs MP4

MTS is based on the MPEG-2 format while MP4 is MPEG-4. Being said that, both have the capacity to produce the same quality of video files given a set of settings. However, using the base settings for these two files, it is easy to see that the MTS file format can capture more details and store more information than MP4. That is the reason why MTS produces a file much larger than the latter. MP4 can produce the same results, although tweaking is necessary to make it at par. However, MP4 is more compatible with a lot of video editing software than MTS.
