I am a professional Digital Imaging Technician on many commercials. The Ultra 3D has paid for itself after two jobs. I use four different softwares to capture video from my Ultra Studio. I do not use the Blackmagic software to capture, although I have tested it and it does the job. As far as a delay, I have not had that problem yet. The unit is of great quality, affordable, portable and it serves its purpose perfectly. My unit has been on dozens of commercials with no problems at all. My only complaint is that the unit does get hot to the touch.
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.
