Summer school video en didactiek: Open Video & MediaMosa, 26 augustus 2010SURFnet. We make innovation work

• Open Source (MediaMosa, FFmpeg)• Open Codecs (H.264, VP8)• Open Media Formats (Ogg Theora, WebM)• Open Standards (HTML 5)• Open Content


Open Video ContentCreative Commons



Open Video StandardsHTML5


• HTML5 is een omvangrijke revisie van de standaard HyperText Markup Language voor het www door W3C.

• HTML5 maakt het o.a. mogelijk om video direct in een HTML pagina te embedden – net als bijv. afbeeldingen nu – en native in de browser af te laten spelen, zonder dat er een externe video plugin nodig is.

• Dankzij HMTL5 is directe interactie tussen video en de rest van de pagina en andere inhoud op het web mogelijk. In combinatie met o.a. CSS3 en JS zijn complexe toepassingen mogelijk.

• HTML5 is momenteel nog in ontwikkeling en ondersteuning verschilt van browser tot browser. Ondersteuning op IE ontbreekt.

Open Video Codecs & Media Formats


• Ogg Theora (voorheen)◦ In beheer van de Xiph Foundation◦ Bij m.n. lage bitrates vergelijkbaar/beter dan MPEG-4/

DiVX◦ Hardware support afwezig en onwaarschijnlijk◦ Geen brede steun van de industrie

• WebM (sinds kort)◦ Samenwerking van Mozilla, Opera, Adobe en Google◦ Vergelijkbaar met de lagere profielen van MPEG-4 H264◦ Hardware support nog afwezig, maar waarschijnlijk◦ Steun van belangrijke spelers in de industrie


Open Video Principles


1. Authorship and Viewing

2. Open Standards for Video

3. Open Distribution

4. A Rich, Participatory Culture

5. Civil Liberties and Basic Rights

Het creëren, bewerken en afspelen van video zou gemakkelijken toegankelijk moeten zijn, middels gratis en open source

toepassingen.









Videostandaarden zouden open, uitwisselbaar en vrij van patenten en royalties moeten zijn.









Videoplatformen zouden neutraal moeten opereren en open standaarden en licenties moeten ondersteunen.









Wetgeving mag participatiecultuur niet ontmoedigen. Videomateriaal zou beschikbaar en toegankelijk moeten zijn zonder

technologische restricties of andere beperkingen.









Mensen hebben het recht op deelname in een democratie, privacy, vrijheid van meningsuiting en distributie van eigen creaties vrij van censuur of beperkende gebruiksvoorwaarden.
