Frequently Asked Questions

What is an AVCHD file?▼

AVCHD (Advanced Video Coding High Definition) is a format jointly developed by Sony and Panasonic for HD camcorders. It stores high-quality video in an MTS/M2TS-based structure.

Why convert AVCHD to MP4?▼

AVCHD folders and MTS files confuse most editors and players. Converting to MP4 makes a single, shareable file that plays on any device.

AVCHD vs MP4 on a camcorder — what is the difference?▼

AVCHD prioritizes quality for editing; MP4 prioritizes compatibility for sharing. Many cameras record both, so choose AVCHD for editing and MP4 for quick sharing.

Does converting AVCHD lose quality?▼

At matching bitrates the visible quality is preserved while making the file far more usable. Keep the AVCHD original for high-end editing.

Are my camcorder videos uploaded during conversion?▼
