ImTOO Video Converter Ultimate 

ImTOO Video Converter Ultimate is a complete solution for Mac users who wish to get rid of incompatibility issues between movie file formats and their media playing devices. This application supports a wide variety of video formats, provides you with pre-defined output profiles, and offers high-quality results in minimum time.

On the homepage of the developer you can choose between three releases of this video converter: Standard, Platinum, and Ultimate. If you ask me, the last one is the most capable of all, as it offers you plenty of movie editing tools, lets you convert 2D videos to 3D format, allows you to preview the results before launching the conversion process, and many others.

The app allows you to change the resolution of your videos, add stunning visual effects, set another bitrate value, and personalize the videos by attaching watermarks. Furthermore, its integrated media player helps you check the resulted movies and decide if you made the correct adjustments.

Another aspect I like about this tool is the fact that it doesn't take long to process the input files, even when you choose to convert more than one file at a time.

To sum things up, ImTOO Video Converter Ultimate proves to be a reliable solution when it comes to changing the format of your favorite movies. This app provides you numerous helpful features, brings a user-friendly interface, and comes with a reasonable price considering its output quality.
