    So, I’ve been digging around for some stereoscopic research for us, and I think I found some interesting stuff. Something we all should consider when developing this project is how the 3D is going to be exhibited. With a little common sense, its pretty obvious that the exhibition of 3D is just as important as the actual shooting process. Whether you’re projecting circular polarization, linear polarization, anaglyphic, or whatever, its important to at least comprehend the science. Also, keep in mind that this is being made for the small screen instead of the big screen. So what does that mean? Well, for starters, edge of frame is so much more prevalent, and since its such a smaller frame, 3D effect might have a completely different effect on audiences than being on a 90 ft cineplex. Sure, issues of parallax and convergence should still be addressed, but I wonder if those issues will be as dominant on a tv screen than in a theatre. So, for those of you who want to be in the know, here’s some pdf docs I found on the post and exhibition process of 3D. These documents come from scientific communities, so the language is pretty dense, but there’s some good stuff here.

    -This is a pdf doc from Michael Sparks. He started a company called StereoGraphics Corp, which was bought out and renamed RealD. He was a pioneer of digital stereoscopy in the 80s and 90s. This guy knows his stuff. It talks about the history of digital 3D projection, and he tackles the process of the projection process. It’s pretty heavy with engineering jargon, but there’s some golden nuggets buried in here.

    -Also, he has a blog.

    -This is a pdf discussing the process of HIT (Horizontal Image Translation). From what I understand, this is the basic concept of creating the 3D image in post (I’m assuming that this is kind of what Quantel’s software does). Give it a read, its interesting.

    -Here’s an interesting article from Quantel. It breaks down 3D production and 3D post. It’s got some good stuff. Definitely read the Appendices.

    -Oh, and I just found this. haven’t read it yet, but it sounds completely relevant. It’s Quantel discussing the Red camera with their work flow.

    Anyway, I hope these docs help.

    Have we chosen our tri-level sync generator for genlocking these cameras? The AJA Gen10 seems to be a popular and thrifty choice for the school. I suggest if we haven’t already gone into purchasing or renting a “sync box” that we consider this as an option.

    Yeah, it might be a pretty good idea to invest in one of these, but from the stuff I’ve been reading the Gen 10 can sync up recording just fine, but it has no capability to sync up the monitoring output. If thats going to be an issue, then we also need to look into getting a frame synchronizer. AJA FS1 is suggested from reduser.net. It looks pretty hefty. We might not even need it since it kind of sounds like you really only need it for monitoring in 3D, which if we have the capacity to do it, it might be cool to test it out.

    Here’s the manual for the AJA Gen 10

    Here’s a pretty insightful article on 3D from FXguide.com
