AVoption|V10
Digidesign's new AVoption|V10 is a professional 10-bit video I/O peripheral that is fully compatible with Avid's new Media Composer Adrenaline media and provides high quality projection in the highest profile environments. Adding AVoption|V10 to a Pro Tools TDM system will enable real-time playback of Avid video directly within the Pro Tools application.
AVoption|V10 can play back any resolution of video content that can be created by a broad range of Avid products, past and present, including Media Composer Adrenaline. Video resolutions include uncompressed standard definition video and DV25, as well as Avid's AVR and JFIF compression formats. Because AVoption|V10 works with the same video files as those on an Avid system, bringing a project into a Pro Tools TDM / AVoption|V10 system will be as easy as importing an AAF sequence.
