Why Trim MTS Files?

MTS is the file extension for AVCHD recordings from Sony, Panasonic, and Canon HD camcorders. Camcorder recordings often start with setup footage, include long pauses, or capture more than needed. Trimming MTS files lets you extract the best moments while keeping the AVCHD format for compatibility with Blu-ray authoring and camcorder-aware software.

This is useful for cutting wedding/event recordings to key moments, removing dead air from interview footage, extracting highlights from sports recordings, or reducing file size before archiving camcorder footage.

Frequently Asked Questions

Which camcorders produce MTS files?

Sony Handycam (HDR-CX, FDR-AX), Panasonic HC-V/HC-X series, Canon VIXIA/LEGRIA, and JVC Everio camcorders all record in MTS (AVCHD) format with H.264 video and AC3 audio.

Can I compress while trimming?

Yes. Under "File Compression," choose any method. Combining trim + compression in one step is more efficient — a 1-hour 1080i MTS file (4–8 GB) can be trimmed to a 5-minute clip and compressed to under 100 MB.

Will trimming preserve the AVCHD structure?

The output is a trimmed MTS video file. Original AVCHD folder structure (BDMV/STREAM) and metadata are not preserved — the output is a standalone MTS file playable in VLC and most video players.

Can I also resize while trimming?

Yes. Under "Video resolution," change resolution during the trim — useful for creating smaller clips for web sharing (e.g., 720p instead of 1080i).

Should I trim as MTS or convert to MP4?

Keep MTS for Blu-ray authoring or AVCHD workflows. For sharing and general playback, MTS to MP4 is more universally compatible.
