We pitched this solution at Hollywood Post Appliance last year the idea of embedding the decoder source code (ANSI-C) into archive master. People really liked this idea. So even if we change the codec in the future, the needed decoder will be present in an archive class bitstream. Plus our current decoder is compatible every HD stream we every Davidhttps://www.blogger.com/profile/11820803180730920007noreply@blogger.comtag:blogger.com,1999:blog-13372801.post-53477639648108474352008-03-15T12:40:00.000-07:002008-03-15T12:40:00.000-07:00Sorry, forgot to add my follow up email address!Sorry, forgot to add my follow up email address!Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-13372801.post-7150209974960323362008-03-15T12:37:00.000-07:002008-03-15T12:37:00.000-07:00Someone is ARCHIVING in the Cineform codec?
