Convert Google Video To AVI Format With Gvi2Avi

Google acquired YouTube in 2006 and subsequently retired its own video upload service in 2009. Google Videos now serves as a sub-search engine for videos. However, material previously uploaded to what used to be Google Video, will continue to be hosted.
Not long after incorporating YouTube, Google discontinued development of the Google Video Player in 2007. It also removed the option to download its hosted videos. As a consequence, the GVI format will slowly die out.
Do you still have videos in GVI format sticking around and wondering what to do with them? Would you like to know how you can download the remaining Google Video files? If you answered yes, continue reading as this article holds the answers to these questions.

What Are Google Video Files Anyways?

Essentially, Google Video (.gvi) files are RIFF (Resource Interchange File Format) files of the subtype AVI (Audio Video Interleave). Compared to regular .avi files, they contain an extra list with the FourCC “goog” right after the header. FourCC is short for ‘four character code’ and identifies the video codec, compression format, color or pixel format used in the media file. In plain English, this means that a simple manual modification of the Google Video file will yield a standard .avi file.
Note that most media players will actually playback Google Video files, including VLC Player, KM Player, and Windows Media Player. Isn’t it interesting though, that Google actually introduced its own file type and hence branded its videos?

So Can I Manually Convert A Google Video To AVI?

Yes. As Wikipedia points out, Google Videos are encoded in MPEG-4. Hence, for DRM-free videos, it’s possible to simply change the file extension from .gvi to .avi. However, that’s a very messy way of converting a file.
If you want to be safe, get a Hex editor and remove the list that makes the difference between the .gvi and .avi file. I used Freeware Hex Editor XVI32. It doesn’t require an installation, just unzip, run the .exe and browse for your .giv video.
The image below shows the sample file before (top) and after (bottom) editing. I removed the first LIST up until LIST2.
convert to avi
Simply click the first item you wish to delete and then click the [DEL] key until you have deleted the last item. When you’re done, go to > File > Save As… and enter a name. You will have to add the .avi file extension manually.

How Can I Automatically Convert A Google Video To AVI?

If you agree that renaming the file extension is amateurish and if you don’t want to mess with a Hex editor, a conversion tool is in order. There are several shareware and trial programs out there that promise to convert GVI to AVI. However, the free ones I tested are huge and not intuitive to use. By far the most effective and simple tool is described below.

Gvi2Avi

This tiny tool does a perfect job of converting .gvi files to .avi. It’s a 96 KB .exe file that does not need to be installed. However, it does require .NET Framework 2. The only real drawback is that you cannot mass-convert multiple files, the tool only handles one at a time.

How Can I Download Google Videos?

Google has removed the option to download its videos directly from the video page. However, there are tools available that can do the job for you. They will download in FLV or MP4 video format, so you won’t have to be worried about the GVI format.

PwnYouTube

For your future Google Video download needs, try the PwnYouTube Bookmarklet. Yes, it does say YouTube, but it actually works with Google Video and other video sources. And this is how it works…
1. Drag the PWNYOUTUBE Bookmarklet button to your browser bookmarks toolbar.
google video download
2. Visit a page with a YouTube or Google Video and click the Bookmarklet in your browser toolbar.
3. On the page you were re-directed to, find links to pages that allow you to download the file as FLV or MP4 files.
google video to avi
Basically, PwnYouTube is a hub for various online download services. For my Google Video source, SaveVid was the easiest option, while the others were rather disappointing. However, your results may vary depending on the source.
And this concludes our little excursion on Google Video and .gvi file conversion. You may now return to YouTube. If you are generally interested in video downloads or video file conversion, however

How To Hide Text In Microsoft Word 2007, Reveal It & Protect It

Sometimes what we hide is more important than what we reveal. Especially, documents with sensitive information, some things are supposed to be ‘for some eyes only’. Such scenarios are quite common, even for the more un-secretive among us. You want to show someone a letter composed in MS Word, but want to keep some of the content private; or it’s an official letter with some part of it having critical data. As important as these two are, the most common use could involve a normal printing job. Many a time we have to print different versions of a document, one copy for one set of eyes and others for other sets. Rather than creating multiple copies and therefore multiple printing jobs, what if we could just do it from the same document?  That too, without the hassle of repeated cut and paste. We can, with a simple feature in MS Word – it’s just called Hidden and let me show you how to use it to hide text in Microsoft Word 2007. It’s a simple single click process. Open the document

Clip & Convert Your Video Faster With Quicktime X & The New Handbrake 64-bit [Mac]

Recently a friend of mine asked for my help to find a video of a good presentation to be shown to one of his classes. He also requested for it to be iPod friendly as he would also distribute the video to his students. Three things came to my mind: Steve Jobs, Quicktime and Handbrake . Mr. Jobs is well known for his great presentations which are often used as references. I have several Apple Keynotes videos. For my friend, I decided to choose the one that introduced MacBook Air – the one that never fails to deliver the wow effect to the non-techie audience. It’s a part of January 2008 Macworld Keynote. First step: The Cutting To get only a specific part of the Keynote, I clipped the 1+ hour video into about 20 minutes using Quicktime X (which comes with Snow Leopard). I opened the movie using Quicktime X and chose Trim from the Edit menu ( Command + T ). Then I chose the start and end of my clip by moving both edges of the trimming bar to the desired position.

Ex-Skypers Launch Virtual Whiteboard Deekit

Although seriously long in the tooth and being disrupted by a plethora of startups, for many years Skype has existed as an almost ubiquitous app in any remote team’s toolkit. So it seems apt that a new startup founded by a team of ex-Skype employees is set to tackle another aspect of online collaboration. Deekit, which exits private beta today, is a virtual and collaborative whiteboard to help remote teams work smarter. The Tallinn, Estonia-based startup is headed up by founder and CEO, Kaili Kleemeier, who was previously a Head of Operations at Skype. She and three colleagues quit the Internet calling giant in 2012 and spent a year researching ideas in the remote team space. They ended up focusing on creating a new virtual whiteboard, born out of Kleemeier’s experience collaborating with technical teams remotely, specifically helping Skype deal with incident management. “Working with remote teams has been a challenge in many ways – cultural differences, language differences, a
