I recently treated myself to a HD camcorder as I will be going on holiday to California soon for a family wedding. I got the camcorder a bit early so I could have a chance to play around with it and practice editing the clips, the camcorder records the clips in a .MTS format which is a High-definition MPEG Transport Stream video format, commonly called “AVCHD;” used by Sony, Panasonic, and other HD camcorders; based on the MPEG-2 transport stream and supports 720p and 1080i HD video formats.
If you've got some AVCHD videos (with M2TS/MTS extension) and want to convert them to AVI videos just like me, you need a Mac HD video converter tool to do this job. I find there are lots of similar programs on the market, after tried some of them, I picked up one called iFunia HD Video Converter for Mac (http://www.ifunia.com/hd-video-converter-mac.html) to convert AVCHD video to AVI for myself. This software is a free trial application for Mac OS X that accomplishes this task quickly and easily. It helps me rip/convert AVCHD video to any common video/audio formats for playback on media players and mobile devices. I’ll show you how to convert the AVCHD videos to AVI format on Mac step-by-step.
Step 1: Download, install & run Mac HD video converter to convert MTS to AVI videos We’ll be using a very nice video converter software for Mac OS called ‘iFunia HD video converter for Mac’ for converting MTS/ M2TS HD video to AVI, head over here and download the free trial version. (http://www.ifunia.com/download/ifunia-hd-video-converter.dmg) Next step is to install the program. Now run iFunia HD video converter on your Mac and click the big button "Add..." to add MTS/ M2TS HD video files, you may add as many videos as you want to convert to AVI videos.
Step 2: Select the video titles that you'd like to convert Only the titles you checked will be converted. So if there're some videos you don't want to convert, you need to uncheck them or 'Remove' them from the right-click menu. 'Clear' in the right-click menu means remove all titles in the list.
