Glasses free 3D display at NAB

At NAB I briefly saw something pretty cool that I wanted to share with you. A huge glasses free 3D display. Yes there is ghosting, but it was pretty cool to be in a room with a lot of other people all looking at the same display each seeing our own perspective of the image with no 3D glasses needed. I wasn't sure the effect would translate through the single lens of my camera... But it did! Check out this walk around video.

Don't use removable mount adapters

This is why I do not recommend removable mount adapters for your lenses. Just look at the dramatic lens movement. This happens everytime you apply pressure through the follow focus unit.

Why I will hire a professional stuntman next time. Or, all the places my body hurts.

Yesterday I did a few stunts for The Red Rider. Basically I repeatedly crashed a motorcycle. The following diagram represents a plethora of muscle strains, abrasions and other nasty injuries I sustained.

Panasonic GH2 8bit 4:2:2

I will preface this post with a caveat: this could be hearsay.

I was given a hack for my GH2 that I was told would generate 8bit 4:2:2 files. It's a very indepth hack created by a a friend of a friend. Obviously the files are still .mts wrapped, so I've been re-wrapping/transcoding them with Adobe Media Encoder.

I've chosen settings that I believe will not modify the original source and output them to ProRes. 1080p, 23.976, ProRes 4:2:2. The process takes about 2x longer than the files length so a 5 second clip takes about 10 seconds to transcode on my 2009 17" Mac Book Pro.

On average, the file size gets a bit smaller (my 356MB file became 199MB), so I decided to compare them.

From my unscientific observations, it appears there is a VERY minor noise shift in the new ProRes. Not objectionable, just different from the original. And a VERY slight gamma shift favoring the mid-tones and smooshing the blacks. These could be the result of not knowing what settings in Media Edcoder I am using, but all in all it appears to retain everything very well. I will be using this workflow.

The ultimate baseplate for future camera systems

http://www.abelcine.com/store/OConnor-Universal-Baseplate-Set/

Oconnor has created a very unique baseplate system that intrigues me very much. with the overly simplistic design, one can adjust the rod height to fit almost any small to medium sized camera on the market.

This could be the perfect transitional baseplate system for anyone who wants to test the waters with a DSLR then graduate to a more capable system in the future without constantly buying accessories specific to the camera system.
