On this page, find where to get and how to use video
capabilities on computers and websites. This page has been around a while,
since before the turn of the century. Attempts have been made to update it, but
stuff toward the bottom may be the most dated. I'm tending to put the newest
material toward the top. At the moment I'm in the process of
collecting information on utilities I've had laying around in various places
into this one place (for my own reference of course, bonus if it helps you as

Leads on Videoconferencing added in 2006
Graham Davies writes in July 2007: "The archives of this Flashmeeting
videoconference on blogging, podcasting and digital video show you what
language teachers in secondary education in the UK are doing in these areas.
The conference was set up by Joe Dale:
- Why Use Video in the Classroom? A National Teacher Training
- Intime has many teaching clips
- Also the Annemberg Teacher Development Project
- DVD Formats Explained (Created February 27, 2003) With so many
different formats -- DVD+R, DVD+RW, DVD-RAM, DVD-R, DVD-RW, DVD-ROM -- how do
users know which DVD format is compatible with their existing systems, and why
are there so many different formats for DVDs? Find out here:
- The Ed Tech Pages: Video - Articles, reviews, papers and useful links
dealing with the use of video in the EFL classroom:
- Video Cassettes and the Internet by Linda Thalman -
- Mark Sellers, MLI, Abu Dhabi, provides this assessment, "This is one of
those, like, wow! Sites for links to video resources on the web. Here's what
you'll find there: "Update: February 1999: 360 million pages on the Web and
I've stopped counting! Scrolling down further on this page you will find:
Movies, Screenplays, Television, Literary resources, EFL/ESL Publisher Videos,
Articles on the Internet, Usenet, Email lists, Thank You and Books for Teaching
Languages Using the Internet." Thank you, Linda Thalman."
- http://www.teachers.tv is a free
TV channel in England to supporting teachers. It has videos of teachers
teaching all manner of subjects.(March 2006)

TESOL 2005 (San Antonio) presentation here:
- Internet Moving Images Archive at
- Next Vista http://www.nextvista.org - started by
Rushton Hurley, is trying to create a free resource of videos on various topics
and somehow organize the library
- The Real English Onlinesite.
Marzio reports, Feb 17, 2007: If you're an ESL/EFL teacher in need of graded
video content, I just finished making the entire Real English video library
both free and free-access. The 100+ spontaneous yet grammatically organized
video clips are all at http://www.real-english.com/reo/index.html."
In August 2007, Mike says: " There are good exercises for students for the
first 15 videos - but you must first sign up and log in to do these exercises.
So perhaps some teachers would like to make up exercises for some of the other
videos which you can see at the free-access section."
- Sites where you can download interesting sound files and video clips
are discussed in "Real Audio to Augment Real Listening in the ESL Classroom" by
- The Ultimate Movie Clips selection at
- YouTube. Jane Pettring notified Webheads of a couple of
"wonderful language-related clips from I Love Lucy: Lucy Hires a Tutor:
and A Matter of Interpretation:
The YouTube interface offers related material through its tagging system so
that, in this case for example, many more I Love Lucy episodes are
- VideoLink Mail from Smith Micro Software at
fairly small video files (around 500 k a minute) which you can send as email
attachments. The files are executable for people with Windows and NT without
their having to download any extra software.
- Cyberlink VideoLive Mail does much the same as above,
Unfortunately (for me :-) the page now loads in Chinese.
What video host is best? Worldbridges.net has a page on "Online
screencast video comparison" at http://www.edtechtalk.com/node/1742
with "examples of the same screencast encoded by different video sharing sites.
The orignial video was encoded as a 640x480 .mov file. They were all pretty
easy to upload and embed. Which do you think produces the best quality video?"
The sample for comparison is a recording of a screencast of an EdTechTalk
episode, so worth watching as well. (Aug 2007) .
Meanwhile here are some sites that have come to the attention of Webheads:
Firewire, compression, etc.
- You need about 16 gigabytes (GBs) of hard drive space to store an
hour of uncompressed digital video.
- To recompress video so as to fit on a 650 megabyte CD - Terran's
Media Cleaner Pro - Google searches now point to

- Webheads tried in March 2007 to help Lee Baber view problematic AVI
files. ElderBob said that the VideoLan VLC player, open source, cross-platform,
will usually play just about any file....even difficult to open ones. No
problems." Lee was also advised to view the video with gspot to see the codec
used to read the file, and to download the XP Codec Pack from
- Casablanca (a non-linear editing device) from Draco.com (http://www.draco.com ) converts VHS into mpeg
or mpeg 2. Cost is about US$5,000. (neteach-l, 08 Dec 1999) (overloaded on Feb 17, 2007 - will try again)
- "When we purchased our Cheetah Video Server, we got it bundled with
an MPEGator Encoder. This consisted of a video card and software that encodes
to MPEG 1. It cost around $5000. I'm quite pleased with it's ease of operation.
I need to purchase software for editing, as the software includes very basic
editing features." - 08 Dec 1999, firstname.lastname@example.org.
- "there's a piece of hardware for $200 called DAZZLE, that you can
pick up at Office Depot that converts video to mpeg." 08 Dec 1999, on
Jason Firestone on digital video
The following appeared on neteach-l, 10 Nov 1999, about video or audio
conferencing pals over the Internet:
- 30 fps (frames per second) is full-motion film picture broadcast
- 30 fps for videoconferencing (VC) with simultaneous audio is
available at connection speeds of 512kbs using either satellite communications
or approximately eight bundled ISDN telephone lines, both currently incredibly
- Television pictures are broadcast at 24 fps.
- Between 10-15 fps can be achieved at 128kbs transmission (using ISDN2
- i.e. two lines) which is considered an acceptable viewing frame rate.
- The transmission rate over the Internet with a 56Kbs modem is
currently extremely poor, at approximately one frame per four seconds.
- Kies et al (1996) experimenting with frame rates under 6 fps found
users expressed "dissatisfaction with the low frame rates resulting in
inattentiveness, distraction, and at times, disregard for the video
- The Internet uses a low bandwidth means of transmitting data which is
insufficient for good quality video and audio conferencing.
- The Internet doesn't have 'dedicated' bandwidth, which means that no
preference is given to video / audioconferencing users over any other
simultaneous users online transmitting or receiving data (such as e-mail or
downloading web pages).
- Due to the fluctuating levels of user demand over the Internet there
is no guarantee of continuous stable rates of audio and video transmission
The following points should be considered for effective audio
- Participants must be allowed to hear each other clearly, and
continuously, without inhibitory factors interfering.
- Significant factors that impede good audio quality are: echo, time
delay, background noise, speaker's distance from the microphone, quality of the
microphone itself, the efficiency of the audio decoder.
- Watson and Sasse (1996:256) note that high quality audio is more
important when using videoconferencing for foreign language learning than for
other tasks by native speakers.

Extensive biography on video conferencing here:
video is "subtitled" film, where the subtitles appear on the screen along with
- Overstream: http://www.overstream.net/ "Have you ever
wanted to customize an online video by adding your own comments or subtitles in
any language, or wanted to send a custom video postcard? All of this is
possible with Overstream: using our online Overstream Editor, you can easily
create and synchronize your subtitles to any online video*, store them on the
Overstream server, and send the link to the subtitled video overstream to your
friends." This demo shows clearly how it works:
- There used to be an interesting document at
http://www.sivideo.com/openoccc.htm on open captioning films. In late 1999 it
was possible to purchase 27 Open Captioned movies for $377.95 ($13.99 each)
plus shipping & handling of $4.50 per order, not per tape. The subtitling
in this case is done in the language of the film, which I believe is English
for all 27 movies.
method of subtitling is closed caption, where the subtitle is buried on a track
which can be viewed give the presence of a decoder. This decoder has been
mandatory on tv's produced in the USA for the past several years.
- WebAIM (Web Accessibility in Mind) has a section on closed caption
software at http://www.webaim.org/techniques/captions/software.php.
- Free: The one they recommend for best balance of needed features
and ease of use is Media Access Generator (MAGpie) Version 1.0 from
"Developers of Web- and CD-ROM-based multimedia need an authoring tool for
making their materials accessible to persons with disabilities. The Carl and
Ruth Shapiro Family National Center for Accessible Media (NCAM) has developed
two such tools, version 1.0 and 2.0.2 of the Media Access Generator (MAGpie),
for creating captions and audio descriptions for rich media.
- Trial available: Hi-Caption Studio
which "allows users to interactively quickly create SAMI files for their media
files for use with the Windows Media Player or for the Real Networks
RealPlayer... with RealText.... Just as you would rather use a web content
editor to create web files, this program allows you to easily create the
formatted captioning file, without having to learn the code behind it but with
the power of making the code accessible."
