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.

To increase the precision, I moved the edges little by little using the left and right arrow buttons.
Then I clicked “Save As” from the File menu (Command + Shift + S)

Second Step: The Conversion

In the computer world, the name Handbrake is identical with video converting. This open source application is available for Windows, Linux, and Mac. In late November 2009, Handbrake just released its latest version: 0.94 with several new features and changes.
To me, the most notable change is the speed. This is because the latest Handbrake is already supporting 64-bit while the old ones are still in 32-bit. This allows the 64-bit build to utilize the real power of Intel Core 2 Duo, even if your Mac is still under Leopard.
Please note that this speed-up applies only to the Mac and Linux versions. Windows users are still stuck with the old 32-bit for some more time.
To convert the video file, I selected the clipped presentation video file by clicking “Source” and browsed to the location. To speed up the process, you could use the search feature.

I, and I’m sure many other users also, don’t know (and don’t want to know) the exact settings of video files which will play along well with the iPod. Handbrake understands this and give its users several pre-configured presets available from the side window.

Just choose iPod from the options and everything will be adjusted accordingly.
If you know what you are doing, you can add more presets to the list by clicking the Plus (+) button on the lower part of the side window.
You could also do several conversions one after another by putting the configured video file to the queue and clicking “Source” to add others.

And after everything is set, click the start button and make yourself a cup of coffee.

In my 2.4 GHz Intel Core 2 Duo MacBook, Handbrake needed a little more than 8 minutes (probably faster because Handbrake’s seconds ticked faster than the menubar’s clock) to convert 140.3MB of .mov file to 113.3MB of iPod compatible mp4.

After the conversion was done, I opened the file using iTunes. It will be synchronized with my iPod the next time I plug it in. I also passed a copy to my friend.

A Little Experiment

I was curious. I felt that the 64-bit build is faster. But is it really faster? I wanted to compare both the 32-bit and 64-bit builds head to head. Fortunately, I still keep an older version of Handbrake. For the sake of comparison, I reinstalled version 0.93 (the 32-bit build) and did the exact same conversion of the same movie file on the same machine.
On a smaller size movie file, the difference is not really notable. But with larger files, the 64-bit build is clearly faster.
These are the comparisons I did using one and a half hours of .avi movie:
32-bit – about 20 minutes (because the ETA counter moved up and down)

64-bit – about 15 minutes or less (because the ETA counter moved down faster than the real clock)

Aside from the speed, there are more features hidden underneath this new version. You can refer to the official site for more information and if you haven’t upgraded your version of Handbrake, now is the perfect time to do it.

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 docum...

Build Your Own Awesome Personal 3D Avatar with Avatara

Do you use social networks and want to build your own awesome 3D avatar? Maybe you want to send someone a cute cuddly image of yourself (kind of)? Or maybe you have your own ideas of what you would do with an Avatar… Well look no further than Avatara which I discovered from the MakeUseOf directory . You can create 3d avatars out of pre-set up templates or create your own from scratch. To start, visit Avatara’s homepage . You will see this screen: Click Get Started to umm, get started! That will take you to this screen: You see that you can build your own Avatar using an uploaded head shot like the Obama one above (just an example, guys). Or roll with one of their awesome avatars. I chose to start with a blank avatar by clicking Start with a blank avatar at the bottom of the screen. That takes you to here: I clicked on the filter at the top and told it to filter out everything but male characters and then I saw this: I rolled with Buck and continued. You need to click Select...

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...
