What is a .MTS file?
MTS is a video file format used for high-definition video. It is part of the AVCHD (Advanced Video Codec High Definition) format, which is based on the MPEG-2 transport stream format. MTS files typically contain high-quality video and audio streams.
Background
The MTS file format is primarily used for high-definition video recordings. It was developed as part of the AVCHD standard by Sony and Panasonic in 2006 for use in their digital camcorders. The format supports 720p and 1080i video resolutions and uses the MPEG-4 AVC/H.264 video compression codec. MTS files are known for maintaining high video quality while keeping file sizes relatively small, making them ideal for consumer video cameras. Due to their high quality, MTS files are often used in professional video production and editing environments. However, the format can be challenging to work with due to its high data rate and compatibility issues with some software.
