FOSS Codecs for Online Video: Usability, Uptake and Development 1.2

Posted by: Anonymous [ip: 124.168.2.120] on January 18, 2008 01:50 AM
thanks for your interesting article.

i wrote a report last year for the Transmission network of social-change online video distribution projects called " FOSS Codecs for Online Video: Usability, Uptake and Development". It's a review of the best available tools for the creation, playback and embedding of online video using Free and Open Source Software video codecs, and a set of recommendations for development to enhance their adoption by social change video projects on the web.

a PDF is available here:

i had a few comments to make.

proprietary video-editors *can* export Ogg Theora/Vorbis - using the QT Xiph component. You can use this to export directly from the Final Cut timeline:

GUIs are now available to create Ogg Theora/Vorbis on all platforms (best solutions are listed for creating both Xvid and Ogg for Linux, Mac and PC):

there are a few issues with the Cortado applet to be aware of, that may impede its uptake, though further development could improve this situation. for example a lack of decent controls and performance issues:

however there are other options for embedded playback of Ogg, which are explored here:

i certainly agree with you about FOSS options for video-editing. i will be sticking with Final Cut Pro for the time-being, as efficiency is so important with editing - my project hours would at least double using a less mature NLE.

i feel Theora is definitely "good enough" now in terms of its efficiency and quality as an encoder (i like your point about the low-quality that people have come to accept from YouTube), and as you point out uptake will have more to do with having easy-to-use applications for the playback and creation of Theora files than with slight differences in appreciable quality which only videophiles will notice.

the report tries to identify these key areas for improvement. we're hoping to find some support for reaching these goals - hopefully some of these solutions will also be applicable to other FOSS codecs as they emerge, including Dirac.

please feel free to contact us if anyone would like to get involved in this development:
