Why Convert MTS to MKV
MKV can hold virtually unlimited audio, subtitle, and video tracks in a single file. Store a movie with dozens of language audio tracks and subtitles in one convenient container.
MKV supports every major video codec including H.264, H.265, VP9, AV1, and more. It is the most flexible container format, accepting virtually any combination of audio and video codecs.
MKV files support embedded chapters with named markers, allowing viewers to jump between scenes, segments, or episodes. Chapter metadata makes long videos easy to navigate.
MKV can store lossless video codecs like FFV1 and lossless audio like FLAC, making it the preferred format for archiving high-value video content without any quality loss.
MKV containers can embed fonts, cover art, and supplementary files directly inside the video file. Styled subtitles display correctly everywhere because the required fonts travel with the file.
About the MTS Format
MTS (MPEG Transport Stream) is an AVCHD video file format jointly developed by Sony and Panasonic. It uses the MPEG-2 transport stream container to store H.264/AVC high-definition video along with Dolby Digital or PCM audio. MTS files are the native recording format for many HD camcorders from Sony, Panasonic, Canon, and other manufacturers.
MTS files deliver broadcast-quality HD video at 1080i or 1080p resolution. However, the AVCHD format has limited software compatibility compared to MP4 — many video editors and media players require conversion before the footage can be used. Converting MTS to MP4 preserves the HD quality while making the video universally playable across devices and platforms.
