converts almost all input files to almost all output formats ,some added features in it are that it can also extract sound files from video,some other features include it can help you multiplex audio and video but i never tried that,it's one of the most easy to use software,some drawbacks are that the converter sometimes may oppose to converting the file.
if the resolution isn't a multiple of 4,some other drawback is that although it converts almost everything to everything but it may be little more on the higher side size wise...conversion can take in background making it possible to run other programs without much of a problem..all in all a good converter for small file conversions..lightening quick easy to use ....i use it mainly 4 small videos
