Professor Nesson would like the videos from our lectures to be edited into something suitable for a broader audience, perhaps incorporating the footage from the second camera, adding some context, adding some supporting materials, taking out the boring parts. This is a logistical/technical problem as well as a video-editing project. Want to do it for just one lecture? Or all of them? Or just help figure out how to get it done?


Slide/Text Features:

LLHD Discussion

I'm no video editing genius, I have limited experience with it, but would be willing to help Kwan Bul (in whatever way I can) if he'd like. I noticed that there was some discussion about the slides and how they weren't very viewable for the extension students. I saw a very good example of a video presentation that incorporated both lecture type video and slides at the Keynote address of the 22C3 conference. [1] go to the page and search for the keynote speech (it gets get good around the middle and Joi Ito is an interesting speaker).

I was really impressed by how well it was done, as usually it is very difficult to integrate video and slide elements into a lecture. The process looks labour intensive, but it would be fun to try and emulate.

Ezi Discussion

AFAIK The Real smil format includes triggers for flipping an associated SlideShow. I believe thats how FAS do the "traditional" synchronised video and slideshow for Distance Ed classes.

In this class we are working with MPEG4/H.264 files and the spec does include some textual features in the "container" specification. I know you can provide special files to Quicktime, VLC and Mplayer etc to trigger on specified intervals (it can be used to provide non-derivative CopyRight-compliant Fair Use editing) irrespective of the video codec used. Staying with MPEG4, we could MUX subtitles or a Slide MENU into the stream - see below for a quick discussion into deviating from the clean standard. May be worthwhile just as a tech demo.

Perhaps if we can get more audience participation in marking event triggers, something as simple as a scripted timed rotation or url call would work with synchronized slides ... or we can just adopt the new features and with it favour one vendor, e.g. download this file if you want the notes in the video stream or go to this special wiki page.

Does the Democracy Player bring anything new to the table?

Bookmarks, Chapters or Timed events/triggers

According to the excellent doom9 guide the MPEG4 format includes bookmarking but due to slow uptake (vague standardization) heavily favouring certain vendors (Apple, Divx etc), its going to corner us into the "recommended clients" backwater to work with it.

IMHO opting in to fancy-features counters the broader audience requirement. I certainly agree that providing optional packs would be worth investigating e.g. subtitles (text notes) for the deaf.

I have used VLC to mark chapters in the class lectures. The process would involve re-upping a modified video and i'm not ready yet to vouch the vlc route as cross-client compatible. I hope to update this page when i have more time to work with the vlc process.

Alternate Views

Tends to be offered in the DIVX and MVK format, can't find any reference to an MPEG4 option. Again this does not counter working around the current standard with complimentary specific-client features etc. Could be as simple as just building a playlist to jump to different intervals in different videofiles.



The stereo audio on the class videos is distracting as currently implemented, the sound veers across channels or is confined to just one. This prohibits/discourages headsets or speakers but is perfectly acceptable and audible for the non-headset crowd. For my purposes (and antiquated iPod) i rip the audio to a vanilla mono mp3 audiofile (only). If this is of value to anyone else, I can provide the modified files or upload them somewhere within the boundaries of the inherited distributed license. --Ezi 23:06, 23 September 2006 (EDT)

Alternate Streams

Another option would be to provide an alternate complimentary audio track, as simple as a backing track? Some open-source music.



Another thing that might be really usefull, perhaps for future classes, is a backchannel IRC group for the lectures, though I suppose the wiki in a way fulfills that role. it would be really interesting to have some backchannel information integrated with the video (much like the slides are integrated with the video in the 223C video) in order to get an idea of what the HLS and other students are thinking. I mean their contribution to the course and the site is invaluable and, in my opinion, the more information that can be squeezed from them the better.

There is now an IRC channel #cyberone established on If anyone isn't sure what IRC is or how to connect don't be shy about asking for help.

IRC would be yet another avenue for discussion, ignoring the low bandwidth-friendly aspect, it doesn't really offer any significant improvement over the communication Channels (Blog Comments, Moodle Journals, Wiki, Forums and to a lesser extent email) already offered. One thing i would really like to see is a little more feed/interaction/interplay between the existing components but realistically we're using disparate tools. We currently check all over to encompass the communication channels already offered --Ezi 22:25, 23 September 2006 (EDT)


  • Lets pick an Open Source client (mplayer or vlc)
  • Lets research optional features which compliment the vanilla video file
  • Lets focus on a single tech demo (subtitles to start)
  • Doom9 is recommending mp4box
