Separating 3D footage for edit
on Jan 5, 2011 at 10:08:15 pm

We're trying to capture stereoscopic footage on an HDcam-SR from an SRW-5500. The tape has both the left and right images on one tape, but we're trying to capture them in two separate video streams for editing. When we jog through the footage on the deck, we can see both streams alternating frame-by-frame, but when we play it real time, only one of them will play or capture. Is there a way to set the deck so that you can specify which stream you want it to output?

Our company is just entering the 3D arena right now, so any information at all about the 3D capabilities of the SRW-5500 would be appreciated.

Thanks.

There are no dual stream 3D capabilities of the SRW-5500. It will only give you one of the two streams.

The SRW-5001 (player only) can play the dual streams and the SRW-5800 can play and record the dual stream 3D.

Sounds like Blackmagic should be inventing a box that splits out the fields....

You mean "Old Ben"? Ben Kenobi?

See:

---AJA Hi5-3D (cheapest, untested, and should ship any day now, if not already)
---Cine-tal Davio (my fav, but expensive - $4K for the box, another 3K or so for the software license "library". Does a heck of a lot more, too.)
---3Ality - popular, but I must claim some ignorance; no practical experience, just anecdotal. I think it costs more than the Davio hardware, but software libraries do not need to be purchased

All have varying degrees of ability to stripe or combine streams into and out of a stereoscopic signal.

Dan,

You should be able to play them separately. In the VTR SETUP menu, it should be item 790.

From the manual:

790 4:2:2 DUAL STREAM select
When playing back 4:2:2 DUAL format tapes recorded with the SRW-1 or SRW-5800 on the SRW-5000/5500, selects whether to play back Stream-A or Stream-B.
Stream-A: Play back the video of Stream-A.
Stream-B: Play back the video of Stream-B.

Pick whichever one you want, record it, then roll back, choose the other and record that.

Righto Mark!

When I said this in my earlier post:

"It will only give you one of the two streams."
I meant to say the SRW-5500 will only give you one of the two streams at a time.

We're waiting to see what's going to happen in the near future as far as 3D monitors go with our SRW-5800 as to not prematurely invest in something that will sooner than later be a waste of money.

Do you have any suggestions for 3D monitoring off the 5800? I know companies are working on I/O boxes like Michael Kammes mentioned which may probably be the crucial "inbetweens" from the decks and the monitors...

The 5800 spits out SDI, so any of the converts I listed above will do that...however unless the signal on the 5800 is muxed into 1 stream (SbS, O/U, etc) the signal will be 2D.

Also, all of the solutions spit out HDMI from the SDI output of the 5800 - perfect for most consumer and pro-sumer 3D Monitors; and some even have pass through IF you decide to feed an older projector or professional monitor.

I did have a client who needed to make 3 masters: 1 master for each eye AND a master that was muxed. They were experimenting with deck control to syn up to 5800's for playback, so they could get full frame of each eye in the future. They did not want to go with the 5800/2, unfortunately. Last I heard, they were still in the testing phases with the Davio.

I don't have a 5800, but I believe that it'll output both streams simultaneously, left on SDI output A and right on SDI output B. That AJA muxer works as I've seen it in use. Combines two SDI streams into one and outputs 3D over HDMI with a choice of how (side by side, etc.). 3D display tech is static for the near future. Active displays with glasses will not be replaced by passive displays any time soon - and glasses-less display tech is still a ways off. Passive display is very nice, but very expensive. If I had to do it now, I'd throw down a couple bucks for an LCD with active 3D that'll take an HDMI 3D signal and get the AJA miniconverter. To get any better quality right now you'd have to spend four or five times the price.

[Mark Spano] "I don't have a 5800, but I believe that it'll output both streams simultaneously, left on SDI output A and right on SDI output B."

Yep, that's what it does and that's only one of its biggest claims to fame.

Thanks for your input Michael and Mark.
I like the features of the AJA HI5 3D and considering we have so many of their other great products, that seems to be a good way to go...

Mark, thank you! We had pretty much given up on it until I saw your post today. Thanks again.
