Key Benefits of Converting from MTS

MTS is the file extension used by AVCHD camcorders for high-definition video recording. Consumer and prosumer cameras from Sony, Panasonic, Canon, and others produce MTS files directly on SD cards. While the quality is excellent, MTS files often need conversion before editing in most video software.

Why Convert MTS Files?

Many editing applications handle AVCHD/MTS poorly due to the highly compressed H.264 video in a transport stream wrapper. Converting MTS to an edit-friendly format like MOV, MP4, or MXF (with a more decodable codec) significantly improves editing performance and software compatibility.
