4,5k is enough for IMAX

Wait. I thought Hollywood films were beginning to be scanned at 6K? No?

Hi,

Scanning at 6K and down sizing to 4K is done but not on every movie. The 4k workflow is still quite slow.

Has anyone notice that a close up in IMAX means having 60% of the frame above the head empty?
True, framing for IMAX is a different story.
 
I always wanted to try out vertical anamorphic on a widescreen sensor!

But I think that you could build a rig that could hold two RED ONE's horizontally, then assemble the image in post. 5080 would be your resulting horizontal resolution and you would have 4520 vertical lines so you'll need to crop and interpolate a little.

But really the anamorphic idea is pretty good.
 
3D!!!

I think that will be the advantage that Red will have. Because the camera is so cheap, it won't cost much to film the movie in actual 3-D.

For big blockbuster movies, a lot of them get tests done to see if they can extract 3-D out of the 2-D recorded image (and do an Imax 3D release). This involves a lot of manual labour, and doesn't work very well on semi-transparent objects such as hair. This is why you don't see that many blockbuster movies converted into Imax 3-D.
 
polispol,

That's a good paper. It's long been held that 35mm negative resolves at a relative 100 lines per mm.

You could potentially shoot an IMAX timelapse movie with a high-end DLSR -- 16 megapixel, say. Something like Chronos. Problem is, how do you do post at 6K (5616x4096)??:eek:
 
can the red one power up my time machine and take me back in time to film a periodic piece set in the eary 1920's? if notttt then i might have to reconcider this choice in camera
 
I think that the main problem with IMAX is that if you want to produce a movie, you have to count with the IMAX corporation. There are no private imax movies in the world, and imax corporation always are in the production of the movie.

Does 4K by 4K count?

In fact, last week on NOVA there were extremely cropped, extremely scaled clips of my large format dome show work incorporated into this program...

http://www.pbs.org/wgbh/nova/blackhole/

The venue I develop for can project 72 fps 4K by 4K achieved by 11 overlapping 1280 by 1024 projectors each showing a slice of the final image. It's a rush to see your work on this. Really.

The RED wouldn't help me much with that... but then, bluntly put, everything else helps even less...
 
Yes, another problem with IMAX is the limited amount of theaters. When the money people lay down their dollars they want to make sure the film will get screen time....There is an IMAX film consortium that gets many of the films funded, but many times those go to those with a track record like MacGillavray/Freeman Films. These films are mostly sponsored by large corporations looking to enhance their public image. Its a tough nut to crack, but nothing is like seeing your footage projected on the IMAX screen.
