Bigasoft AVCHD Converter 

Bigasoft AVCHD Converter is a video conversion tool that can be used to convert, play and edit AVCHD files on your Mac. AVCHD stands for Advanced Video Coding High Definition, and it is a popular format used by high definition digital camcorders to record video. As its name suggests, it allows for the recording of high-quality and high-definition video, but the problem often is that AVCHD isn't supported by many devices. That is why this converter can be quite helpful when the need arises to convert your recordings. Some of the formats that this application can convert files to are H.264, MPEG-4, WMV, MOV, MKV, AVI, DivX, ASF and MPG. It has conversion profiles for the most popular devices, including Apple's iPod, iPhone and iPad, other smartphones and gaming consoles like the Xbox 360 and Playstation Portable. There is a list of HD formats as well, and those can take advantage of the high resolutions your videos are recorded at. However, keep in mind that the application doesn't give you the option of leaving the resolution as it is in the source file; it will always change it, either to 1280x720 or to 1900x1080, depending on which HD profile you want to use.

The app comes with all the extras that you will find in a commercial converter these days: a video editor to trim and crop your videos, adjust their properties and add watermarks, and a video player that lets you view your videos before conversion and take snapshots of them.

In short, Bigasoft AVCHD Converter works well and it has good format support. If you don't mind about the little issue with video resolution, then the app is all you probably need to convert your files.
