I came cross an interesting presentation “Mobile 2.0″ today. The presentation was created by the author of mTrends, Rudy De Waele, and delivered at Plugg Conference in Brussels on March 19, 2008. Plugg is a conference which shares a European perspective on Web 2.0 and focuses on raising global awareness for European start-ups in the Web / Mobile 2.0 field. In his presentation, Rudy discusses the Mobile 2.0 and why you should care. He examines the historical development and explores the latest trends in the mobile web.

Besides Media-convert.com I reviewed in my last post, there are two other excellent video converting services. They are YouConvertIt and Zamzar. Both of Web services can be one stop conversion shop that lets you covert WAV to MP3, JPEG to TIFF, DOC to HTML, and AVI to MP4. Both sites will convert the file and send you a link via email where you can download the newly converted file. They are free to use and there is no need to download anything.

Zamzar


Zamza
is a free online file conversion tool. Zamzar can convert your video, audio, images, and documents from nearly any format to nearly any format you like. The file conversion process takes only a few minutes. Up to five files can be converted simultaneously. When the conversion process is completed, Zamzar e-mails you a link to the converted file. The files are kept on the servers of Zamzar for 24 hours. The maximum file size is 100 MB, but there are no limits on the number of files converted. If you sign up for an account with Zamzar though you can upload files up to 1 GB in size. ZamZar can convert between 8 image formats, 16 document formats, 9 audio formats, 13 video formats, and 9 compressed formats.

Zamzar is very easy to use and has a better interface and design than Media-convert. However, Media-convert also allows input files to be locally stored or from a URL, saving users an extra step if a file is on the Internet. Also, Media-convert converts the file while you wait, and gives a download link on screen when the process is completed. Since no registration is required, users are not required to give up an email address as they are with Zamzar and YouconvertIt.

YouConvertIt


YouConvertIt
is a Web-based file conversion service with a Web 2.0 touch. Like Zamzar, YouConvertIt lets you upload audio, video, image, or document files and convert from one format to another. All you need to do is select the file from your computer, select your target format, and the file will be uploaded and converted. Once the conversion is complete, you will receive an e-mail containing a link to allow you to download it within 7 days. YouConvertIt offers a large range of file conversions with 8 audio (AAC, MP3, WAV,..) 72 image (JPG, GIF, PNG, …), 13 video (AVI, WMV, 3GP, MP4, …) and 46 document types (.DOC, .PDF, …). You can convert up to 5 files at a time.

Unlike Zamzar, YouConvertIt does not have a file size limit. Furthermore, you can convert measurement units like size, area, distance, time, velocity, mass, etc and has an online media download manager for Youtube, Metacafe and Google videos. To download videos from Youtube, Metacafe and Google, you simply enter the URL of the file and then either convert it directly or download it to your computer.

Both of Zamar and YouConvertIt are fast and convenient. They are useful, particularly when converting flash movies to MP4 for viewing on an iPod. They are great tools for teachers and students who need to convert a file and do not have a good desktop program.

Media-Convert

Media-Convert is a free Web service that converts audio, video, and text files for you, from and to virtually any kind of format. No software is needed to covert files with Media-Convert. You only need your favorite Web browser. Furthermore, you don’t have to register.  I think this is one of the best media conversion tools for teachers and students.

Converting a file is quite easy with Media-Convert since it allows input files to be locally stored or from a URL. The maximum file size conversion is adequate for 150 MB.  To convert a file located on your computer: Check File mode, click Browse and choose the file, select input format and output format, submit the form. To convert a file located on a Web: Check URL mode, enter the file URL, select input and output format.  Media-Convert converts the file while you wait, and gives a download link on screen when the process is completed.

The conversion formats supported by Media-Convert is very impressive. There’s a good chance Media-Convert supports almost every document on you computer, including most popular video formats (3G2, 3GP, AMV, ASF, AVI, DPG, DV, FLI, FLV, GIF, GVI, MKV, MOV, MP4, MPG, NSV, OGM, RM, SWF, VOB,WMV), audio formats (WAV, WMA, 3GP, MP3, OGG, AAC, AMR, FLAC, MPC, MMF, AU, AIFF, QCP), over 60 image formats, compressed archives (7Z, BZ2, BZA, CAB,GZ, LHA, LZH, RAR, TAR, TGZ, YZ1, ZIP), and documents from Microsoft Office, OpenOffice.org, Lotus 123, raw text, HTML, XHTML and more. In addition, you can insert a PDF into your Web page by converting it into an Adobe SWF Flash movie. You can also capture Web pages as images and convert Microsoft Access databases to Excel spreadsheets.
