48fps SbS Full 3D quick test (be gentle)

[Petri Teittinen]

Hi all,

as there's been lots of talk about the use of 48fps for 3D, I decided to shoot a simple test. Here you go:

48fps_test_SbS-full.avi (28 MB)

Shot on RED One (M) using a $150 plastic lens, so lower your expectations wrt image quality. It's in Side-by-Side Full, i.e. frame size is 3840x1080, and so far I've only managed to view it on a combo of Stereoscopic Player for Windows (www.3dtv.at), Nvidia 3D Vision kit and a 120Hz 3D PC monitor.

NOTE: There's way way way too much horizontal parallax. Use Shift and Left arrow to decrease parallax when viewing on the Stereoscopic Player until it looks bearable to your eyes.

edit: File replaced with a lighter (lower bitrate) version which plays a lot smoother.

180 degree shutter? Looks nice at 48fps, but staccato when dropping every other frame to make it 24fps.

Free-viewing gives a pretty decent 3D effect without having to worry about the horizontal offset, once you crop the frames to be of equal size for each eye.

I for one look forward to seeing what Peter Jackson et al do with the increased frame rate.

180 degree shutter?

At least, might have been even faster; I shot several tests using various shutter angles.

Looks nice at 48fps, but staccato when dropping every other frame to make it 24fps.

Naturally

Did you try 270 shutter? Curious to see what Peter Jackson is up to.

Did you try 270 shutter?

Unfortunately no. I'm not really a fan of slow shutter, and went the opposite direction for these tests. I checked just now, and the clip I posted was shot with 45 degree shutter.

I replaced the file in the first post with a new encode. This one runs a lot smoother on my PC.

Hi,
What Monitor are you using to wach it at 48 fps in 3D?
