ERightSoft has announced a new version of their free media file transcoding tool, SUPER 2011, which is now able to convert many more codecs, containers and file types.

Top of the list has to be support for WebM videos. Google’s sponsorship means the format is sure to become much more common this year, but most desktop applications don’t yet know how to handle it. So it’s good to know that, if you run into difficulties, SUPER can quickly convert your movie to AVI, WMV, or some other more accessible format that you’ll find much easier to use.

If you’re tired of audio compression schemes that ruin your sound quality then you’ll also appreciate SUPER’s support for more lossless codecs, including huffYUV, Lagarith, and Apple’s ALAC. The latter, for instance, allows you to create audio files that are compressed by around 50%, yet don’t lose any sound quality, and will play on all current iPods, iPads and iPhones.

SUPER can now also read, play and write M4A audio files, and APE, AC3 or MP3 audio in a MOV container. Which isn’t exactly revolutionary, as we’d have thought the previous versions should have been able to do this, but at least the program can handle these files now.

And the update also adds support for a range of codecs that are old, obscure, or maybe both, like Cinepak (in ASF and WMV files) or Yamaha’s VQF. You may not care about these – and frankly we don’t, either – but then you never know when you might run into some old video or audio file that uses them. And if you do, then SUPER’s ability to convert them into something more convenient will be very welcome.

If you have a copy of SUPER already, then, or you’re looking for a way to convert audio or video file formats, then SUPER 2011 is worth installing. The program is free of charge and available now.
