Why MP4
Camcorder MTS and M2TS files play poorly on phones and the web. The H.264 picture and the AC-3 sound are copied into an MP4 in seconds, with nothing re-encoded.
Questions
No: nothing is re-encoded. The tracks are moved into an MP4 container as they are.
AC-3 sound is kept, which Chrome and Firefox can’t play; TVs, iPhones and Windows can.
No. The conversion happens right in your browser, so your file stays on your device. There is no account to make, either.
