Frequently Asked Questions

MTS and M2TS are file extensions for AVCHD (Advanced Video Coding High Definition), a format developed by Sony and Panasonic for HD camcorders. It uses H.264 video compression and stores footage in a structured folder hierarchy on SD cards or internal memory.

Sony Handycam, Canon VIXIA/LEGRIA, Panasonic HC series, and many other consumer HD camcorders from 2006-2018 used AVCHD format. The files appear in PRIVATE/AVCHD/BDMV/STREAM folder on the camera's storage.

MTS files have limited software compatibility. Many video editors, social media platforms, and devices don't support AVCHD natively. Converting to MP4 ensures your footage works in any editor (iMovie, Premiere, DaVinci), uploads to YouTube/Facebook, and plays on all devices.

Both MTS and MP4 can use H.264 encoding, so conversion can be done with minimal quality loss. Use 'High Quality' or 'Best Quality' settings. Since MTS is already compressed, avoid multiple re-encodings—convert once to your final format.

AVCHD stores videos in PRIVATE/AVCHD/BDMV/STREAM/ with separate index files for chapters and metadata. This tool converts individual MTS/M2TS files. For preserving the complete AVCHD structure with chapters, use dedicated software like AVCHD Merge.

Currently, this tool processes one file at a time. For batch conversion of multiple clips from a camcorder session, convert them sequentially or use desktop software like HandBrake for larger projects.

Camcorders often split recordings at 2GB or 4GB boundaries due to FAT32 file system limits on SD cards. Each clip becomes a separate MTS file. To join them, convert each to MP4 first, then use a video joiner tool.

AVCHD typically records at 1920×1080 (Full HD) at 50i/60i (interlaced) or 1080p/720p. The output MP4 maintains the same resolution. Interlaced footage may show combing artifacts—consider deinterlacing for best results.

MTS and M2TS are essentially the same format—just different file extensions. M2TS is more commonly used on Blu-ray discs, while MTS is typical for camcorder recordings. Both contain AVCHD video and can be converted identically.

No. All processing happens entirely in your browser using FFmpeg WebAssembly. Your personal video footage never leaves your device—completely private and secure.
