I have mentioned video media conversion tools before, but most of them have been applications. These are fine for example if you have the right computer (you need a Mac for VisualHub) or you have administrative rights to install the software on your Windows computer (which in institutions is generally not the case).
So if you can’t install a conversion tool on your computer, how do you convert video files, well I have been looking at online video conversion tools for a while now.
The one I have used and found the results work well on mobile devices is Media-Convert.
It’s quite simple, you upload a media file from your computer, and an online conversion converts into the file format of your choice. It can handle a large number of file types including text and audio as well as video, and has a range of possible output file types.
It can be used to create PDF files which is handy.
The user interface could be better, it is covered in Google ads, but it is free and they need to make money somehow.
I was impressed with the quality, I took a large Quicktime movie and converted it into an MP4 file that could be used on my Nokia N73, and the conversion was done very well.
I was recently told about another online media conversion tool, Zamzar, however the site is populated with pop-ups and you also need to enter an e-mail address which smacks to me that my e-mail might be harvested and passed onto third parties.
