720p24 @60 frames per sec. at night
 
This clip was captured the other night. With just the lights you see in the movie.
720p 24 over cranked to 60 p @ shutter of 96 @ 0db. It is untouched on the exposure just imported into FCP and exported as a Prores422

Just kidding. No flame wars.

Thanks to Barlow and his kids.

Here is a windows version.

Broken link

Absolutely some of the cleanest blacks of any HD camera I have ever shot with.

Christopher Barry November 29th, 2007 10:55 PM

Chris, thanks for posting links.

As an Win XP user: I d/l the PhotoJPEG mov, and it shows "Error -2048: the file is not a movie file", when loaded into standard QT Player. Anyone else?

Bill Spence November 29th, 2007 11:07 PM

Same problem here. I can't open it in WMP, Quictime Player, VLC, or import into Vegas. It must have been uncoded wrong for windows.

Buba Kastorski November 29th, 2007 11:48 PM

What's the viewer for the files, it's not native .mov's

The mac version looked beautiful blown up to 1920x1080 on my 24" dell.

Barlow Elton November 30th, 2007 11:59 AM

Thanks for letting me play with the camera, Chris!

Christopher Barry November 30th, 2007 10:55 PM

Chris, any chance of posting a few uncompressed still 720 frames, so we can play with them in post on the PC? Thanks

Thanks Chris, I appreciate you posting those frames.

I find it amazing that the camera is so detailed you can see the effects of 4:2:0 sampling/compression quite easily. Would be interesting to compare frames from the HDSDI out as well.

thanks, chris

I'm sure SDI would look better, but please explain what in these images that make 4:2:0 so obvious?

Believe me we ALL want 4:2:0 (4:4:4 for that matter), but 4:2:0 can make some real nice images.
I plan on buying Cineform's recorder or the XDR to tap 4:2:0 via SDI.

I'm not hearing many people complain about the visuals of DVD, BluRay and HD-DVD, all of which are 4:2:0.
When it's said and done, unless you plan on going film transfer, this is the media format.

I find the footage amazing...Talk about lattitude...That camera probably has the most exposure range I have ever seen in a digital camera. I think we can say goodbye to limited contrast ratio. In my opinion that was always a much bigger problem in the past than compression issues.

Excellent. Thanks for posting the footage.

Eric Lagerlof December 1st, 2007 12:05 PM

Thanks for the stills... I couldn't access the footage either. Pretty incredible to see details in both the lightpost fixture and the dark building doors in the 2nd shot. And the darker areas are so nice and clean.

M. Gene Hoffman December 4th, 2007 03:45 PM

Great Footage
 
Hey, thought that looked like the Gateway- very nice footage!

I am amazed at how clean it is, especially for being at night, and fast enough shutter to see detail, and 60fps.

Wow.
