MTS to MP4 Converter
Convert AVCHD camcorder MTS footage to universal MP4, in your browser.
MTS is the AVCHD format used by many camcorders. It holds high-quality H.264 video but is poorly supported by editors and players. MP4 carries the same video in a universal, editable container.
Conversion happens on your device — large camcorder files stay local and private.
