Many programs open F4V files since it's a popular video/audio compression format. Adobe's Flash Player, as of Version 9 Update 3, will open F4V files, as will Windows Media Player. Many other standalone programs from other developers will play F4V files as well such as several Nero products.
Adobe's Premiere Pro video editing software program is able to author F4V files, as are other popular video editing and authoring suites.
