How to Convert AVCHD to MP4 on Mac Free (MacOS 10.6 and Later)

By Cecilia Hwung | Last Update:

AVCHD, short for Advanced Video Coding High Definition, is the video format jointly developed by Sony and Panasonic for high definition consumer camcorders in 2006. AVCHD is compatible with the Blu-ray Disc format and is suitable for the playback of high-definition video.

Things can be a little tricky for Mac users when your Mac cannot recognize or transfer AVCHD files. The thing is, Macintosh computers do not support AVCHD video recorded in 60p (1080 and 720). And iMovie didn't support AVCHD Lite until version 10.0. So in this article, we'll show you how to convert AVCHD to MP4 on your Mac.

Convert AVCHD to MP4 without Losing Quality

Video quality should be the primary consideration when converting AVCHD to MP4 Mac. You don't want to get a blurry MP4 from the original high-definition AVCHD file after conversion. Secondly, the AVCHD converter should support both progressive and interlaced scannings, since AVCHD supports varieties of scanning methods depending on the camcorder model. More importantly, it should have no limit for the AVCHD file size.
