2D to 3D post conversion?

mick@...
 

I am asked by my producer to investigate a possible 2D to 3D conversion project. Though I have shot native 3D movies before, a 2D to 3D movie would be new for me. Any hints for best practice while shooting? Companies with good references? (it's a international co production)
Cheers

Hi Mick,
 Since you know 3D well, the difference for conversion for you would be little, just a couple of things,
Best practice when shooting is to imagine the things you already know like when something in FG will be distracting or uncomfortable and good angles for 3D. And know that some shots requing tons of roto and VFX tricks like snow, confetti, smoke etc will take your budget away from other shots looking as good as they could later when time and money are dwindling.
Get the framing guide setup with VFX and the post house pipeline for working and delivery sizes early and tested in advance of shooting. If you're going Alexa its easy to mod the xml to get exact rez and guides you need and insert to camera to see the final delivery area with stereo sludge on sides that conversion needs (so does live 3D but conversion has a specific amount, and its' good to get the math right for the best least degrading scaling later).
Test through the entire pipe so there aren't weird conversations about color later and why color onset diverged into post. Sure this is the same issue with VFX movies but now with conversion every shot is VFX (but not named). And check the stereo adjustments and HITs to make sure they aren't scaling anything other than whole pixels if stereo sludge doesn't give enough coverage.
Manage their strereo choices early in the tests on early work, or at least work with the director so its done later. Talk with the conversion sups and teams, they should be reflecting on your cinematography based on your onset choices of angle, lens etc, not going rogue.
Conversion lets you bend space and do some things you wish you could do when shooting live 3D. Respect that its different and not inferior in many ways and take advantage of that stereo composing that conversion allows.
There are only 3 large conversion companies left and just a couple very small ones that do a few shots in major features.. Have them do a test of your early footage for this film in you can or at least show you some shots after the first circle takes that must be in film.
Lots more, but it's late here, and I imagine with your shooting experience this all obvious stuff.

Tim Sassoon does excellent 2D-3D conversions, I hear.

Thanks, Jeff

Mick, all that Graham said.

We actually don’t do 3D conversion much any more, other than “capture to CGI”, which is kind of a different thing. We only have one client we still do 3D conversion for, a major studio for their own stuff, because in general, it’s become a low-quality, low expectations market driven by price and schedule, and the main reason it’s still done to features generally is for entree into the Chinese market, which favors 3D versions for their foreign film quota.

We don’t want to get involved at that level, so I try to avoid any 3D conversion work bidding under $35-50K/minute, which is high these days. Because we only want to work on projects where key creatives are involved in the 3D, not just a post supervisor, so there’s an expectation of a quality result with the 3D used in a meaningful way, and enough schedule to achieve it.

A good example of what’s going out from the big three these days is Black Panther 3D.
