[DDN] comparison of video blogging compression techniques
Hi everyone, One of my video blog viewers asked me for an explanation of various quicktime compression techniques I use to make my online videos smaller for different audiences. I've just published my response: http://www.andycarvin.com/archives/2006/04/andys_video_blogging.html In this demonstration, I start with a 10 megabyte video shot in avi format, 30 frames per second, 640x480 pixels, 16 bit stereo. I then produced seven compressed versions of it, including ones that utilize varying frame rates, screen sizes, compression codecs, and audio compression. The most compressed version I created is 97% smaller than the original avi video, and is potentially quite suitable for video blogging in low-bandwidth situations around the world. Some examples: Original uncompressed video (10 megs): http://www.andycarvin.com/video/demo-nocompression.avi Significant compression (1.8 megs, 82% reduction): http://www.andycarvin.com/video/demo-3ivx.mov Extreme compression (292 bits, 97% reduction): http://www.andycarvin.com/video/demo-3ivx8bit160.mov Here's a chart featuring all of the videos and their settings: http://www.andycarvin.com/compressiontable.html Anyway, I hope this is useful for those of you exploring the world of video blogging. thanks, andy -- -- Andy Carvin acarvin (at) edc . org andycarvin (at) yahoo . com http://www.digitaldivide.net http://www.andycarvin.com -- ___ DIGITALDIVIDE mailing list DIGITALDIVIDE@mailman.edc.org http://mailman.edc.org/mailman/listinfo/digitaldivide To unsubscribe, send a message to [EMAIL PROTECTED] with the word UNSUBSCRIBE in the body of the message.
[DDN] Open Source Computer Asset inventory/help desk application
Dear All, I am looking for an open source computer asset management/helpdesk application that I can use within my project. I have some that I am evaluating (mainly from sourceforge). Is there anyone out there who has successfully implemented a computer asset management application? I would be interested in comparing notes.

[DDN] COUNTRIES: NIGERIA : LIBRARIES: Nigeria: Nigeria's Library System: Is It Collapsing or Transforming?
COUNTRIES: NIGERIA : LIBRARIES: Nigeria: Nigeria's Library System: Is It Collapsing or Transforming? Nigeria: Nigeria's Library System: Is It Collapsing or Transforming? Daily Trust (Abuja) ANALYSIS April 14, 2006 Posted to the web April 14, 2006 Uthman Abubakar All Africa.com http://allafrica.com/stories/200604140376.html Economic and global technological developments, most prominently, Information Communication Technology (ICT), are having tremendous impacts on Nigeria's library system, portraying it as collapsing or transforming, depending on the conception and perception of the traditional values and functions of library one holds. The impact of each of these factors depend on and vary according to the nature and statutory functions of each type of library in the country's development system. More striking are developments in the libraries of universities and higher institutions and the national library. The current situation of university libraries, for example, is partly deplorable due to the depreciation of the value of the country's currency, the Naira, in foreign exchange, and the virtual paucity of funds for the regular acquisition of hard copies of materials - textbooks, journals and all other necessary research and learning materials; and partly gladdening, due to the transformation they are undergoing from their age-old essentially hard-copies form, to the electronic or digital form, thanks to the ICT. In the entire library system, university libraries have better funding generally. They were well funded previously by the National Universities Commission (NUC), Professor Doris Bozimo, the Ahmadu Bello University Librarian, recalled, lamenting, But because of this foreign exchange we are now experiencing, we find that whatever amount of Naira we have, by the time we change it to Dollars or Pounds, we get very few books, and right now, there is very little funding for university libraries, because Vice Chancellors are not even able to pay salaries. Complaining passionately of very little funding, she admitted that university libraries in the country now, do not take normal delivery of books and other volumes because generally, funding for the universities has dropped drastically. So a lot of their libraries do not have the resources to buy the books. 95% of the books universities use are imported, and we don't have the funds to buy them. Very few university libraries now buy books from abroad, because the resources are simply not there. We have some books online, but they are very few.

[DDN] Drupalib: a place for library druplers
hi Digital Divide Network community - i first learned about drupal from DDN member taran rampersad. drupal is a very flexible and powerful free content management system (CMS.) see http://en.wikipedia.org/wiki/Drupal for those of you who work in libraries, here's a new web site for library people interested in use of drupal. this message below is from the web4lib email list. - phil Message: 13 Date: Mon, 24 Apr 2006 20:19:06 -0700 From: Mark Jordan [EMAIL PROTECTED] Subject: [Web4lib] Drupalib: a place for library druplers To: Web4Lib [EMAIL PROTECTED] Message-ID: [EMAIL PROTECTED] Content-Type: text/plain; charset=ISO-8859-1; format=flowed Hi, I've set up a website for people who are implementing, or who are considering implementing, the Drupal Content Management System in libraries. Drupalib (http://drupalib.interoperating.info/) is intended as a place for Drupal implementors to share ideas, configurations, themes, and maybe even to incubate the development of some modules that allow commonly desired functionality in library websites. It's based roughly on drupaled (http://drupaled.org/), and features a blog, a forum, and a listing of drupal sites implemented by libraries. Mark Mark Jordan Head of Library Systems W.A.C.

Correction Re: [DDN] comparison of video blogging compression techniques
Hi Andy Others may have caught this. But you got my attention when your post listed the extreme compression example as 292 bits. Wow! Actually, I show 288 kB once I downloaded it. Good work!
