With millions of videos on YouTube, everyone has those few favorite ones that they want to watch again and again. Here are two very simple methods to loop a YouTube video clip or in other words put it on repeat so it automatically starts again as soon as it is finished:

1. Tweak YouTube URL to loop a clip:

Suppose, this is the URL of the YouTube video you want to loop:

http://www.youtube.com/watch?v=aNtZ3Gdo9P4

Tweak it to

http://www.youtube.com/v/aNtZ3Gdo9P4

and add &loop=1 at the end of the URL so the final URL becomes:

http://www.youtube.com/v/aNtZ3Gdo9P4&loop=1

This will loop your YouTube video clip and keep playing it until you stop.

2. YouTube Repeat:

If the above method sounds too complicated, here’s an even simpler one.

In the URL of the video, change youtube to youtuberepeat and let everything else remains the same.

So change from:

http://www.youtube.com/watch?v=sVa1Obny1Uc

to:

The other day i received a note from Dave asking about a simple workaround for converting a Powerpoint 2007 document with .pptx extension to a Word 2007 extension file (docx format).

If you are looking to create a set of handouts using Microsoft Word, you should be aware that Powerpoint 2007 includes a built-in function that allows you to export Powerpoint slides and create handouts in Word (see screenshot below).

Note that you will be able to customize the look of your handouts (setting the position of the notes relative to the slides and so forth).

If you are looking to use Powerpoint slides in a docx format document, i would recommend that you switch to the slide sorter view in Powerpoint 2007 and then select all slides you want to copy to Word. Then on Word 2007, paste special your slides as Bitmap Images. After that. go ahead and manually arrange the slides as you see fit in Microsoft Word.

Doris sent me a quick note asking for some help in converting a .pptx file to the pdf format.

First things first: .pptx is the file extension used for Microsoft Powerpoint 2007 files. In the past, we have provided a simple tutorial for opening a pptx file with Powerpoint 2003 or earlier.

As far as converting pptx files to pdf format there are two possibilities:

1. Office 2007 users can convert pptx files to pdf within Powerpoint 2007, by using the Save as >> PDF or XPS command.

2. Office 2003 users should user a 3rd party tool as a pptx file converter. Usually i am not keen to install ad-hoc desktop applications for such tasks, and prefer to ouse online converters. From my experience Zamzar works best for pptx conversion.

I also received two questions from readers asking for a simple way to convert a pptx format to docx (Word 2007) and swf (Flash). I will try to answer that in the blog in the upcoming days (they already got answers by e-mail).

Question:

Jean asks: Can i open a power point with open office??

Answer:

Thanks for your question, Jean. Sure you can, it’s pretty easy. At OpenOffice make a File>>Open, then select Powerpoint as the type of file you would want to open. Once opened you will be able to keep your file as an Impress or Powerpoint file. That’s pretty much it. Similarly, you can open doc (Word) and xls (xcel) files.
