Frequently Asked Questions
What is MTS format?
MTS (MPEG Transport Stream) is the AVCHD container used by Sony, Panasonic, and Canon HD camcorders. It contains H.264 video and AC-3 audio.
Are my files uploaded anywhere?
No. Processing is entirely client-side via FFmpeg.wasm — files never leave your browser.
How big can my files be?
Limited by your device's RAM. ~2GB on desktop, smaller on mobile. Browser memory is the constraint.
