I've added my opposition to the MP4-on-WikimediaCommons debate - Number 258: I'm opposed to MP4 support in Wikimedia projects. 1) I expect Wikimedia to be a Free-As-In-Freedom champion. That means eschewing proprietary data formats. 2) I have no trouble accessing FAIF video formats. Everyone is free to make their own software and hardware choices; it is easy to choose SW and HW that will play Free video formats. 3) It is true that there exists more MP4 video content than FAIF video content. Once the MP4 camel has its nose in the door, the small amount of FAIF content won't be worth the effort to maintain. As soon as the Wikimedia Foundation needs to cut costs, the low-use FAIF content will be the first to go. Then everyone will be forced to purchase non-FAIF software to participate. 4) Does Wikimedia have the capacity to store video in both MP4 and FAIF formats? Won't that be expensive? https://commons.wikimedia.org/wiki/Commons:Requests_for_comment/MP4
