On previous threads about useful video conversion software I have often mentioned Super as being a great simple program to convert any video formats. I am taking that advice back and just want people to know in case they try it.
I used Super for the last 6 or 7 years, and I have always been happy with it (Granted that I was converting non-critical videos from my crappy SD cameras).
I used it for the first time again last week when I wanted to convert videos to IS format (A codec not supported by my now standard batch convertor in Corel Video Studio). The latest version comes with bundled malware and adware that is a PITA to remove. I went through four spyware programs and eventually reset Firefox to get rid of everything.
It includes OpenCandy which pops up ads around the borders of your browser, and MySearchStart, a browser that just links to other browsers. Both of these took me hours to remove.
In addition, this was the first time I used it to convert to the MJpeg format. And the output was terrible. I didn't check the files after converting; I just uploaded them straight to IS, as I was pre-occupied with removing the crap from my PC. Only when IS sent me Deactivation letters to say the files were approved in error and the quality was not good, did I go back and check. And they were indeed awful pixelated messes.
