4U M2TS Converter is an easy-to-use program that lets people convert not only M2TS files, but also MTS, M2T, and AVCHD videos into a variety of other formats. It's nothing fancy, but its intuitive operation makes it a good choice for this kind of file conversion.
The program's interface is quite basic and uncluttered, and even inexperienced users will find the program's functions obvious. Users simply select the file or files they want to convert, select the desired output format and video and audio options, and click OK. The program quickly converts the files and saves them in a specified destination folder. We were quite impressed with 4U M2TS Converter's variety of output formats; there are 30 to choose from, including formats for portable devices such as the iPhone and Zune. The program also has a scheduling feature, allowing users to delay the start of a conversion until the designated day and time. This is a great feature to have if you have large files to convert and are concerned that the conversion may affect your system's performance. The program's built-in Help file is brief but adequate. Overall, the program didn't knock our socks off, but we found it to be a very practical and effective way to convert M2TS, MTS, M2T, and AVCHD video files.
4U M2TS Converter is free to try, but the trial version converts only 60 percent of the source file. The program installs and uninstalls without issues. We recommend this program to all users.
