DeVeDe 3.16.8, create DVDs from video files

Posted by madhavkobal on 24/07/2010

DeVeDe Screenshot

DeVeDe is an application that converts various video file formats into a disc that can be played in a DVD player. Other applications and tool chains can be coaxed into doing this but DeVeDe has the advantage of being a dedicated utility that has been designed for a single function.

What DeVeDe can’t do is convert video files into other arbitrary formats or distill the contents of a video DVD into a single video file. As you might have guessed, there are no facilities for actual video editing within the program. However, you could team DeVeDe up with a dedicated video editor if you need to make changes to the source material.

When you first launch DeVeDe you are presented with a menu that allows you to choose between output formats. Apart from the ability to create standard DVDs, you can also make video CDs and DVDs with DivX files for players that support it.

Next up, you are taken to the main interface that allows you to add video files and titles to the disk. Each project is made up of a series of titles that are selectable from the main menu of the finished DVD. These titles, listed on the left of the screen, are associated with one or more video files, listed on the right. The source video files can be any video format that the system can understand and you can mix different formats within the same project. There is a submenu that allows you to adjust settings such as quality and aspect ratio for each video file. The DVD menu itself can be customized to some extent by selecting a background image, a font and a music file.

A bar in the middle of the main window shows you how much space you have left on the DVD. If the bar exceeds 100%, click on adjust and the program will automatically lower the quality settings to fit all of the video files onto the medium.

When you have the project arranged you can begin rendering the DVD image. This can take a long time, and thankfully, there is an option to render a short preview to test your settings. The finished file is output as a .iso file, ready for burning to disk.


Although the options aren’t as comprehensive as some other programs, I don’t think that there any absent features that 90% of people will actually need. In contrast, a lot of applications of this sort force the user to become of a bit of an expert in video standards and container file formats. It’s also worth mentioning that the help file is complete and details every part of the program. All in all, it’s a great little utility that does everything that it should. Recommended.

Element OS – Home Theatre OS

Posted by madhavkobal on 21/06/2010

Overview of Element

Bridging the divide between the internet and television…
Element is a free operating system for home theater PCs, media center computers, and set-top boxes. Featuring an innovative “across the room” interface designed to be connected to your HDTV for a digital media and internet experience from within the comforts of your own living room or lounge. Element comes loaded with the software needed to stream all forms of web content  and manage your own multimedia library and downloads.  We’ve included many popular open source applications, each adapted to our unique interface, such as the Firefox Web Browser, Pidgin Messenger, and XBMC Media Center, along with access to numerous on-line content services from Hulu, Cooliris, Boxee, Clicker, Amazon on Demand, Youtube XL, and more.

Our aim has been to design an environment that is simple and intuitive while not sacrificing aesthetics or the ability to customise your system. We’ve enhanced a traditional mouse/keyboard driven environment through our unique implementation of a ten-foot user interface, providing our users a streamlined multimedia and internet experience they can pick up the essentials of in minutes and enjoy from across the room on there HDTV. If you have an Android handset then you can conveniently use it as a remote or purchase any of the affordable handheld keyboard/trackpad remotes compatible with Element in our Hardware section.

Unlike similar home-theater systems (Roku, Popcorn, etc) that are based around a single media center app or framework, Element is a complete application platform. What this means is even though Element comes preloaded with XBMC for media management and Cooliris for streaming content, you can add any number of apps or services such as Boxee, Hulu Desktop, Moovida, and to name a few.  Our system isn’t just for running different types of media software either, Element provides a full fledged computing and internet experience with hundreds of applications available all morphed to fit in our ten-foot user interface, from web browsers, to word processors, movie editors, photo managers, and most anything else you can imagine. You could even use Element as a gaming console with many 3D and general games available. In total over 1500 applications and almost 500 games are currently installable with a single click through our partners AllMyApps Software Center and our own Addons/Extra section.

Posted by madhavkobal on 17/06/2010

Free and Open Source Video Editors for Linux: I’ve shared with you a list of free and open source video editing software  before, and noticed that there are other excellent video editors for Linux that I failed to mention. So today, I would like to feature some more video editing software, which are all capable of handling video sequence editing and provide tools for trimming, colour manipulation, titling, visual effects, splicing, cutting and arranging clips across the timeline among others. The best thing is that these editors are free and open source:

Posted by madhavkobal on 14/12/2009

With the Video Downloader, you can download video from Youtube or any other streaming site. Rare are the sites you will not be able to download from. This integrated a flash video player too, so that you can play your files immediately.

Surf your favorite video sites with the addon in Firefox. When a downloadable video is detected, a small message box, similar to the one that indicates your downloads have completed, will appear. Click it and the video will be downloaded and saved to your hard drive. The Download button from the toolbar has the same function. Click the ‘explore’ button to access all the downloaded files easily.

You can download videos from Youtube and all the big sites. Most addons do this well. However, this technology will work with unknown sites too. Rare are the video sites you will not be able to download from.

There is an expert mode available too (activate it in the addon options), if you wish to find the exact URL of the video files on their source server, among other additions.

You can watch all the videos you have downloaded immediately by clicking the Player icon. You won’t have to find an external player which could potentially be bundled with malware. Note that you are able to start watching a video even while it is still being downloaded. It can be useful in a situation where you are uncomfortable with a site’s player or if there is too much buffering.
But If you desire to watch your videos outside of the addon, it is not a problem either. You can do whatever you want with the files. They are saved as they are found: their format is not changed. We only rename them, for your convenience.

Additionally, we have integrated our Ant Rankings to the addon, so you can know instantly if you are browsing a popular site, or smaller, potentially dangerous, website. If you are curious about this site we encourage you to click the Rank button to find more informations about it.

  • Smart sorting with user configurable leading word filter to prevent sorting on common words like the, a or an.
  • Support for play lists. Play lists may be played in a certain configurable order, or browsed through like the main music library.
  • Export music library and play lists to XSPF,PLS,Extended M3U,M3U and CSV.
  • Clipboard & DND (drag-and-drop) support to arrange playlists and dragging to and from gnome / kde applications.

Please note that to install it in Ubuntu, you can’t have Nvidia 190 drivers (because libxine1 depends on nvidia185 drivers).

Moovida logo

If you’re like most computer users, your hard drive is probably stuffed to the gills with movies, pictures, music, and media files you want to hang on to. If you’re trying to figure out a good way to manage them all, have a look at Moovida, an open source media player that’s so snappy you might kick your current player to the curb.

Moovida is loaded with more features than one person could probably ever use. Media is searchable by artist, song, TV show, movie title, or file name. Thumbnail and slideshow images of cover art or image files display beautifully and put CoverFlow to shame.

Moovida pics

Moovida supports all video formats including .mov, .flv, .divX, and .mkv — even the elusive .ogg. It’s got full HD support and allows users to access online content via plugins. Moovida will even pull plot synopsis and actor lists from the Internet, and display subtitles for all your favorite foreign films.

Moovida movies

Moovida lets you integrate your music library with online content services and has plugin support for Shoutcast, Grooveshark,, and RTBF radio.

Moovida music

One of the neatest things about Moovida is the ability to share media content from your computer directly on your TV. In fact, unlike many other media players, Its user interface is optimized for TV viewing and includes remote control support. Moovida automatically detects peripheral devices like digital cameras, iPods, and USB hard drives, making adding or transferring files a snap.

If your media file directory rivals that of the Library of Congress, then you need to give Moovida a try. Its easy to install and makes managing your media content a real joy.
