Can someone please shed light on this setting from finchers film?!

What was/is "4kOS"?

 

[Michael Tiemann]

I'd guess "OS" is "over-scan". In the BTS videos I've seen, they made a big deal about having lots of extra room around the shooting area for post purposes.

This is the second time I posted about this as I am very very interested in what was going on with their cameras. I'm surprised nobody actually knows what this is/was, we are all just guessing lol

Well, judging by this photo i found they shot 2:1, so my next (2) question is, 1. If they shot 2:1, why was it called "OS" and 2 "How would i go about setting up the user action marker to this on the RED LCD? What would the numbers in px read on the monitor. I'm interested in experimenting with this. Thanks

what always confuses me is that anytime i try to cut into a RED image its like zooming into it and it just looks compressed and artifacty

That could have been a custom name for a guide or something RED did for them as a custom thing in the FW. Generally the Fincher films are being shot on first gen cameras and FW with a couple of RED tech's there for support.

4K OS could easily be a name the production gave to frame guides or a build for them.

but I can't really see what you are talking about based on the file you uploaded.

I can't speak to this specific movie, but on house of cards they shoot a 4k framing inside of the 5k (first couple seasons, now probably 5k inside of 6k) so as to have a bunch of room for reframing the shot or image stabilizing it. Basically any shot with camera movement gets stabilized. Depending on which director, they really tend to frown on panning or tilting the camera (especially tilting, all headroom changes are done on the boom on the dolly).

They usually had some Fincher build on the cameras. But thats more than likely what you are referring to.
