3herosoft MP4 Converter is a video conversion tool that you can use to convert your video files into the two formats that are most frequently stored in MP4 containers: H.264 (also known as MPEG-4 AVC) and MPEG-4. These formats are the most widely supported formats these days, and most modern devices will play them just fine. In fact, this converter comes with a bunch of conversion profiles, which are pre-configured conversion settings for specific devices. The iPod, iPhone, iPad, and some other video playback devices all have conversion profiles available. The new iPhone 5 is even already supported.
There are HD profiles as well and this brings me to one feature that I like a lot about this app. In most converters, you can't specify the resolution of the file that you want to convert, and there isn't an option to keep the resolution intact. In other words, those converters change the resolution of your video to 1280x720 for example. 3herosoft MP4 Converter gives you the option of manually entering the resolution that you want to use. I would love an option to keep the resolution intact, but manually entering it is a nice workaround.
I also like that the developers offer two versions of this app, one for Intel and another for PowerPC processors. This allows users of older Macs to be able to use the application.
In conclusion, this video converter works quite well, it has good input format support, an original interface, and a video editor. It has all the features that you would expect from a commercial conversion utility.
