I gotta tell you that I’ve done a good handful of 3D tracks in my time and have never fixed the lens distortion as part of the process. My tracks are still dead on. But that being said I make sure to use great quality lenses. Unless yours is insanely distorted, you may not notice a difference.

I’ll go so far as say that I hate the look of rendering fields. I think interlacing alltogether needs to die out. It’s an old requirement for old technology and needs to just go away. If I ran the world, the broadcast standard would be 24p. Mostly to save film costs. I shoot 30fps now to match video frame per frame without needing a pulldown. But it costs a bit more. I personally don’t see a difference in 30p to 24p, but there is a hell of a diff between 30p and regular interlaced video. But because it would be cheaper and the same standard as motion pictures, 24p is my vote. Rendering in fields means you will see 60 changes per second and I think it looks way too hyper real. I love that kind of framerate for video games but not entertainment.
My opinion of course 🙂

Don’t need a card. Assuming you have any straight line along the X, Z, or/and Y axis, you create a couple user lines over where the hard edges are and it will figure out the correction.

Other options are doing it in Flash or hand drawing it the ol fashined way and using a simple shareware program to grab frames and show you the onion skin from your previous frames.

A lot of that stuff is sampled from real life. People shoot images of their own paint splatter, ink spills, crunched up paper etc and use them as track mattes.
A quick solution for edges is to use the ‘Roughen Edges’ effect in AE.

Any 3D tracking softwre does this already. Since you need to get a track anyways, I’d use the software, it’s internal pipeline is everything you need, to undistort the image and get a proper track.

I use AE 7 with a Decklink. The standard way is to go to your video prefs and set the output to Decklink using the “Blackmagic RGB” codec. Then you will see your work exactly like it is on your comp monitor.
As far as rendering fields, it really is an artistic preference (that many don’t care for). If you’re sending video to something, it still is technically giving it fields, it’s just happens to be the exact same image on every pair of fields. Rendering fields in AE basically samples the positions of objects every 60th of a second (base 30fps) instead of every 30th. But just like the look of interlaced video which is 60 new images a second, people find it offputting and prefer progressive video or rolling film at 30 fps and under for a more artistic feel of motion.

So you’re seeing it fine thru your decklink, but instead of a progressive render, you want the motion rendered in fields using the RAM preview? Out of curiosity, why field rendering? We talked about this a while back and most ppl concluded it’s not asthetically pleasing. It’s “Hypercrisp” like old video switchers. Is there a technical reason you want it rendered in fields?
