Video transcription project

This page describes the video transcription project for the elinux wiki.

Overview

The purpopse of this project is to create transcripts of ELC and ELCE talks, as pages on the elinux wiki, via crowdsourcing. The value of transcripts would be that the material in the talks would be much more accessible to people. It would be searchable, and the talk could be read instead of watched (which is time-consuming). This essentially makes the talk accessible via random access instead of sequential access. There is a lot of very good content that is preserved in the videos that have been made over the years, and the goal of this project is to make that content more accessible and usable.

Process and methodology

In order to crowdsource the effort, a structure and method will be developed for:

  • keeping track of the completion status of each talk
  • managing the transcripts and keeping them in a uniform and useful form
  • keeping track of who has worked on each talk (transcript credits)
  • reviewing the transcripts for accuracy (and vandalism)

Random idea: Maybe use a different wiki for the talk pages, that allows database operations on the pages (like websed/tbwiki tables).

Process per page

1. check if page is listed in global presentation list 2. create a presentation page for the presentation (using a template?) 3. add a link to the talk in the global presentation list 4. add a link to the talk in the global topic list

Here's a link to the List of Embedded Linux Presentations

Tasks

  • add a status column to each conference's talks page, indicating the transcript status and linking to the talk page.
  • add a page for each page, with the presentation's information (title, description, author, transcript, link to video, etc.)
    • make a template for a presentation page
  • solicit participation in the project
    • make a call for volunteer transcribers on celinux-dev and at ELC Europe

Development notes

  • need to investigate a way to have the presentation pages be consistent. MoinMoin has template pages, what does wikimedia support?
    • investigate wikimedia page creation
      • This seems to be supported, in a very limited way, and only with plugins, via a "preloading" option.
      • MoinMoin is much better here, suggesting at page creation time any page that has a template with a prefix or suffix that matches the to-be-created page.
      • I guess we'll have to settle for just trying to be consistent
      • Maybe the page creation could be automated
        • Should I write a script to create a presentation page, and associated link on the 'list of presentations' page?
  • need to create global presentation list (working on it, decided to add session incrementally)
    • have a separate page for presentations by topic?

The first session I tried was the Samsung fragmentation page from ELC - unfortunately, there was no video for this. The second session I tried was for Mike Anderson's keynote from ELC 2012 - setting up the page was a bit of a pain. Very clear instructions are needed for this. It should be as mechanical as possible, with little room for error.

How much time does it take, per minute of video?

They use square brackets for comments like [laughter], [music], or [pause], and angle brackets to indicate a speaker change.
