Check out this thread. Clearly, even though the A1 does a good job with Greenscreen in HDV, component output makes for really clean comps.

I've been looking for info on this exact subject., re composite vs firewire capture.

I have the XH-A1 (which I love dearly) and am trying to find a way to get the absolute best captured footage out of it for a project I've currently got going. For this project the camera is locked down in an overhead rig shooting straight down. We don't need sound for it (I usually record sound separately anyway and sync in post), just the clearest richest image we can get under controlled studio lighting.

I have tried capturing directly from On Location via firewire straight to disc, but the footage seems to be exactly the same as that captured from the tape via firewire, which makes sense to me.

However, we're using a 24" Samsung HD touch screen monitor as the preview monitor for the shoot, (the same monitor that this particular interactive HD application will be ultimately delivered on), to get the focus as sharp as humanly possible. We're going into the monitor via component for the preview.

One thing I noticed is a very big increase in the overall visual quality of the signal on that monitor when viewing via component. Colors are richer and more realistically saturated, and strangely, the focus is much more sharp.

When I capture the footage via firewire from the tape, it's noticably duller, on the grey side, and slightly fuzzy, like it's a bit out of focus. Still don't understand the drop in focus though. Why would that be, other than I really may not have had it in focus to begin with; but I had two other sets of sharp eyes to confirm the focus on the monitor.

But hooking the component outs from the camera to the component in on the same monitor at the same time I'm looking at the captured footage in Premiere Pro CS3 shows that same taped footage looking pretty much exactly like it looked when we were monitoring it live. I'd like to be able to deliver that better looking footage as our end result (h.264 full 1080p at a data rate of 10-12Mbps or more), if at all possible.

I'm about to buy a Xena LHe and Cineform Prospect HD in the hopes that I can get the very best out of the camera, since it looks like I might be doing a lot more of these interactive HD projects in the near future.

The increase in complexity and time for the component workflow is not a deterrent to me. Ultimate visual quality is the goal. Even if I had the XH-G1 I'd still have to have a similar capture capability and workflow for the digital SDI footage, correct?

Eventually we'll most likely go to the RED in the future, but that's a whole other story.

Actually, I wonder if there is anyone in the DFW area that has a Xena setup like the one I mention above. I'd be more than willing to pay for the time it would take to capture a test of our latest shoot (approx. 3 minutes) so I can do some more R&D. If anyone has or knows someone locally with such a rig, I would greatly appreciate contact info.

DVinfo is a fantastic educational resource and it has taught me so much. But I've got a long way to go before I understand all this as deeply as I need to.

Thanks for any input from any of you knowledgable types out there.

Hi Doyle, I searched the XH A1 forum for all of the threads I could find which discuss component video capture and have now merged them into one large discussion. You had posted to our XL H1 forum and I have moved your post to this thread since you have an XH A1. Please review the entire discussion thread thread here. Thanks in advance,

Doyle Calvert May 3rd, 2008 02:43 PM

Thanks Chris. You're certainly on top of things. I saw my post show up someplace I didn't put it when I went back to the XH-A1 forum and wondered how that happened (still a newbie on these fine boards).

I've been reading that very interesting collection of threads you put together. Very useful. Much appreciated!

Don't know if this really answers any questions, but I found this ( http://www.blackmagic-design.com/pro...videorecorder/ ) to be a great option.

Blackmagic
 
this is interesting -
would it allow for HD 4:2:2 recording?
it shows a full res capture preset...
Really?

if you record through the SDI would it record HD
it states 1024 video

ideas?

To me it looks like it does only SD.

John Benton May 8th, 2008 12:20 PM

Alas,
So close...
and yet,
so far
