HD video: on my own domain, archive.org, blip.tv, Vimeo or Youtube?

December 27, 2010

There’s so much video content available on the web today, with many different styles for sharing.  The variety of considerations can lead one person to favour an approach that isn’t quite right for someone else.  After months of trial-and-error, I’ve compiled a comparison of web movies hosted on (1) my own domain, (2) Community Video on archive.org, (3) blip.tv, (4) Vimeo, and (5) Youtube.  I was motivated to share the experience of the Beat, Breaks & Culture festival at Harbourfront Centre in Toronto on July 11, in which my third son Noah performed in the final battle between Ground Illusionz and The F.A.M.

I’ve summarized my assessments in a table near the bottom of the (long) page.  The essential considerations include:

(a) Website blocking / Internet filtering? Is web site blocking (more formally known as Internet filtering) by national governments (e.g. by China and other countries); in public libraries (e.g. content judged offensive or inappropriate); or in workplaces (e.g non-work-related use) a concern?
(b) Media containers? The H.264 (MPEG-4) standard is emerging as a new leader, with Flash Video common as a plugin to most browsers but not supported on Apple products.  Digital cameras may produce AVI, MOV (Quicktime) or other formats, while different browsers natively support Theora (Ogg Video) and WebM.
(c) Browser embedding and linking? Once the web movie is on the Internet, how easy is embedding into a blog post, and/or creating a web link?

Digital photos: capturing, archiving, printing, web sharing, photoblogging

December 22, 2009

Digital cameras have become so common that they’re often now a feature in mobile phones and audio players.  Pressing a button to capture a snapshot of time is so easy.  The workflow of storing, printing and sharing those images is complicated.  Many would like to return to the days when we would just take the film cartridge out of the camera, and drop it to a photo lab for processing (often in about an hour).

People take more photographs digitally than they did with film cameras.  In a six-month study in 2000, when digital cameras were relatively uncommon, subjects (aged 24 to 38) took 200 to 1000 (with an average about 500) photographs, compared to their prior non-digital accumulated collection of 300 to 3000 (with an average of about 1000) pictures (Rodden & Wood 2003).  This means that when digital cameras were relatively expensive — and camera phones didn’t yet exist — people were averaging about 1 to 5 photos per day!

People presumably use cameras because they want to be able to retrieve the images later.  In a study of 18 parents, the value of long-retrieval of family pictures was high (i.e. around 4.7 on a scale of 5).  On experiments of 71 retrieval tasks — finding birthdays, family trips, first pictures of a child, etc. — 61% were successful, taking about 2.5 minutes each.  On the 39% of unsuccessful retrievals, subjects gave up after about 4 minutes  (Whittaker et al.… Read more (in a new tab)

Blogging, microblogging, webstreaming

November 26, 2009

While some of my activity on the Internet is recreational, I continue to play with web tools to learn about the ever-evolving technology.  While the average person has become comfortable with e-mail, web feeds are still pretty much a mystery to many.  The RSS and Atom specifications first used by newswires has become the principal form of web syndication for blogs and social media.

I’ve recently rearranged my pattern of web use (again).  To encourage readers to think about how they use the Internet, let me pose four questions.

  • 1. Which principles on web content do I have in mind?
  • 2. How do I post content, and flow it?
  • 3. Why have I recently changed my use?
  • 4. What consideration should web users have for their content?

With the way that technology continues to evolve, the specific web applications may change … but the pattern should remain the same.

1. Which principles on web content do I have in mind?

My attitude is reflected in two ideas:  (a) open content with attribution, and (b) open platforms with interoperability.

(a) Open content with attribution reflects that I like to share my learning with other people.   Posting the content on the Internet improves access and distribution.  I understand the workings of copyright — there’s a Creative Commons license on this blog — which means that I retain ownership of my words, on the condition that if someone wants to formally cite the work, he or she should cite me as the source. … Read more (in a new tab)

      Generative AI, such as ChatGPT, may be better viewed as putting together hypotheses, where testing either leads to corroboration or truthiness. > The glitch seems to be a linear consequence of the fact that so-called Large-Language Models are about predicting what _sounds right_, based on its huge data sets. As a commenter put it in […]
