Generation loss — quality may degrade
M2TS uses lossy compression, and so does MTS. Converting means decoding and re-encoding — each cycle can permanently degrade quality. Convert from the original source file whenever possible.
Some metadata may not survive
Your M2TS file may contain Blu-ray metadata metadata. MTS has limited or no support for these metadata types. Location data (GPS), camera settings, and color profiles may be stripped during conversion.
What compression artifacts to expect
MTS lossy compression can produce blockiness (H.264). At the high quality settings CocoConvert uses by default, these are usually invisible to the eye. Lower quality settings trade visual fidelity for smaller file sizes.
您手中的M2TS视频文件，是否正让您在分享或编辑时感到一丝不便？特别是在面对主流播放器兼容性、移动设备支持，或是上传到常用社交平台时，M2TS格式有时确实显得有些“格格不入”。而MTS格式，作为AVCHD标准下的另一种封装，在许多场景下与M2TS文件几乎是同源同质，但在某些特定设备或软件中，它却能提供更流畅、更少障碍的使用体验。我们深知，高效便捷的影音处理是多么重要。因此，我们为您提供这款免费的在线转换工具，旨在帮助您轻松将M2TS文件转换为MTS，让您的珍贵影像资料在各种平台间无缝流转，享受更广阔的创作与分享空间。

What Happens When You Convert M2TS to MTS
Your M2TS video is transcoded — video and audio streams are decoded and re-encoded into the MTS container. This is a lossy process that takes time proportional to the video duration.
Your M2TS file is demuxed — video, audio, and subtitle streams are separated
The video stream is decoded frame-by-frame, then re-encoded with MTS-compatible codecs (typically H.264 for MP4)
The audio stream is decoded and re-encoded (or copied if the codec is compatible)
Subtitle and chapter data is preserved where the target supports it
Streams are muxed into the MTS container and the file is saved
