What an MTS file holds

MTS is a video file in the AVCHD format, the standard used by many consumer and prosumer camcorders to record high-definition video. The .mts extension holds the recorded stream as it comes off the camera, using the AVCHD structure built on H.264 video.

AVCHD wraps H.264 (AVC) video and Dolby or PCM audio in an MPEG-2 transport stream, the same stream type used in broadcasting, which is why the extension is MTS (MPEG Transport Stream). This design suited recording to memory cards and discs, letting camcorders capture efficient high-definition video reliably.

Strengths and limits

MTS delivers efficient high-definition video straight from the camera, using H.264 compression that balances quality and size well, and it is a recognised standard across many camcorder brands.

The transport-stream packaging is meant for recording and broadcast rather than editing, so some software handles it awkwardly, and the .mts files from a camera often reference an AVCHD folder structure. For editing and sharing, the video is usually rewrapped or converted.

MTS Development History

MTS was introduced in 2006 as part of the AVCHD format, developed by Sony and Panasonic. This format aimed to provide a high-definition recording solution for consumer camcorders, addressing the need for a compact and efficient video storage method. Prior to MTS, consumer video formats were limited in quality and storage capacity, often requiring larger media or less efficient codecs.

The adoption of MTS grew as camcorder technology advanced, leading to widespread use in consumer devices. Over time, MTS became standardized, supported by various editing software and playback devices. This ensured compatibility across different brands and models, solidifying MTS as a key format in the video production landscape. Its integration into professional workflows also helped bridge the gap between consumer and prosumer video production.

Practical Use of MTS

Choose MTS when recording high-definition video with consumer camcorders that support AVCHD. It is ideal for scenarios where video quality is paramount and file size must be manageable. Common workflows include direct editing in NLE software that supports MTS, such as Adobe Premiere Pro or Final Cut Pro. Be aware that some platforms may not natively support MTS, necessitating conversion to a more widely accepted format like MP4 for broader compatibility.

When converting to or from MTS, consider the potential loss of quality, especially if changing to a lossy format. Use reliable conversion software that maintains high fidelity. Additionally, be mindful of the file structure within AVCHD, as MTS files often reside in a folder hierarchy that should be preserved for proper playback. Always check the target device's specifications to ensure it supports MTS playback or editing capabilities.

Working with MTS files

You will encounter MTS files as the recordings from AVCHD camcorders, typically stored within an AVCHD folder on the camera's card.

To edit or share the footage, convert MTS to H.264 in an MP4 container, which keeps the same efficient video while using a container that editors and devices handle smoothly.
