This product has some inherent limitations, not the least of which is its inability to record analog audio without a video signal present. Most professional editors require the ability to record temp VO from time to time. Not only does Media Composer not support that option with this interface but it wouldn't work even if they did. The hdmi playback is nice but delayed and the need to capture everything via blackmagic's capture software and then transfer to Avid is ludicrous.
