How to Convert AVCHD M2TS to MP4 with High Quality

Advanced Video Codec High Definition (AVCHD) is a recording format jointly developed by Panasonic and Sony for recording high-definition video to media such as recordable DVD media, hard disk drives, and memory cards. It usually ends with .m2ts or .mts which is made to multiplex audio, video and other streams in high definition.

However, you may encounter problems when you try to watch your AVCHD M2TS videos on a computer or mobile device, upload them to the internet or edit them in video editing apps. Actually, a M2TS file recorded by AVCHD camcorder is not quite friendly to regular computers, and not compatible with most video editors and players either. In this case, you need to convert AVCHD to MP4 format for better compatibility.
