Intensity Pro workflow with Z1U and Cineform at DVinfo.net

James Huenergardt · May 4th, 2007, 11:12 AM

Thought I'd ask this question here so everyone can benefit.

With Black Magic's release of the new Intensity Pro card which accepts Component analog input, I was wondering how this would all work with either Aspect HD or Prospect HD.

I understand that to realize the full benefit of bypassing the Z1U's compressor, one would have to go from camera/component/Intensity live instead of from the tape.

What I am wondering is if there is any benefit to using the Intensity Pro card to capture video from tape instead of using the i.EEE/firewire connection.

Also, if you use the Cineform codec with Adobe Premiere Pro (either Aspect or Prospect) will you be able to utilize the HDMI-OUT on the Intensity card to view playback from the Premiere Pro timeline? What about After Effects?

I would think not. The compression has already happened. All is left is a digital file transfer for ingest. (I'm sure there would be a hit going from digital to analog). Besides, why not just capture with cineform via IEEE and upconvert to 10bit for 10bit precision on your edits? At least there would be no further loss.

I guess I was thinking if I could get the same quality, but get HDMI out for editing in PP2, that would be nice.

I guess my question now might be can you view a regular Cineform file on the PP2 timeline out the Intensity Pro to your HDMI TV? Or does the Cineform clip have to be captured via HDMI/Intensity to view out the Intensity card.

We are not using the Intensity for output from Prospect HD/2K, only AJA cards are setup for that. This may change but not any time soon.

negative. The component signal is before the Mpeg 2 compression on the z1U, so there are no compression artifacts if you can capture that signal. This makes shooting green screen a little easier to deal with.

John,

Peter was correct as the question asked was -- "What I am wondering is if there is any benefit to using the Intensity Pro card to capture video from tape instead of using the i.EEE/firewire connection."

I misread, my bad. Sorry for the mix up
