I Shot a 6K IMAX Video with the S9

The video was shot in open-gate 6K. The 3:2 aspect ratio of the sensor is close to the IMAX AR. The video was rendered in 1.43:1, the IMAX aspect ratio. There are no black bars cooked in the video. If you click on 'YouTube' and watch the video on YouTube there will be no black bars displayed.

Now, before anyone objects that this is not "real" IMAX, note that almost all IMAX movies are shot with cameras that have less than 6K resolution. IMAX has designated a set of digital cameras as officially IMAX. These include ARRI cameras that have a max resolution of 4.5K and the Sony Venice, which is 6K. Dude, Part 2 was shot in 4.5K (ARRI's), Top Gun in 6K (Venice).

The true IMAX camera shooting film produces 12K images. There are only 30 theaters in the whole world capable of projecting the 12K film version of IMAX. All other official IMAX theaters project in either 2K or 4K no matter how the movie was shot.

So, yes, this video can be displayed on an IMAX screen in an IMAX theater.

6K frame grabs:

As usual, excellent framegrabs. The future is indeed 99% video (except for some special cases where for example rolling shutter would be an issue or absolutely the BEST DR / color resolution is needed) as we can just extract any frame from them.

Assuming we use a high-enough shutter speed to freeze action/ camera movement blur and also assuming we don't need blur. I've noticed your water fountain video used a low shutter speed for decent water blurring - that's for example an exception.

I agree with this. This video was entirely shot at 1/60th of a second at 30 fps (the 180 rule!). This gives natural-looking motion in the video and sometimes is effective for still grabs that have motion as you say.

Muad'Dude!

Seriously, though, the footage looks great. The guitar player has quality Michael Hedges style chops too.

BTW, for flowing / falling water / snow / rain / duststorm, I almost always dial SS down to 1/30s (360 degrees) unless I need to do camera movements and also plan for future framegrabs of the latter.

Thanks for posting the video and screen grabs.
