Daniusoft Video Converter is a multi-format video converter. It has very good format support. The following formats are supported: WMV, MP4, AVI, MKV, MPEG, MOV, M2TS, FLV, 3GP, ASF, VOB, and DV. The app can open any file in any of those formats, and it can convert to any of them as well.
This video converter uses a very original user interface. When you first open it, you will see a space that reads "drag files here". And to the right is a black space where a video player will be after you load your files. When you do load them, they will be listed on the left, and each file will show its name, size, and duration. By clicking on the icon on each file on your queue, you can choose the output format and play a bit with the settings. There are lots of different conversion profiles and you can change the settings for each one. From the MenuBar, you can launch the trimmer, cropper and video editor. When you open one of those the main window will show a transition effect and show the new window. When you close, for example, the trimmer that you have just launched, the main window will appear again with another transition effect.
Daniusoft Video Converter works very well, it supports lots of formats and it has good video editing features.
