Tell me if I'm wrong, but I read the D4 video specs and it says 1080i (not 1080p) for uncompressed readout. I'm not a video man, but I think this could be a snag for some.

I think its the separate RGB channels that are interlaced at a higher frame rate. This may be done to reduce motion artifacts.

Can u pls explain a bit more,? thank u.
1080i won't be giving the same image as 1080p. then whats the advantage we got from D4, i know uncompresses thing, but does really improve the quality over 1080p+H.264?

Start at the top of page 13. This explains how the canon-c300 uses a faster frame-rate interlaced set to produce 1080p. I presume the D4 will do something similar.

Here is a sample D4 video, pretty impressive shallow DOF stuff.  Nice tracking shots too!

The C300 has an HDMI out, so why can't it pump out raw?

neuroanatomist, teaching people as usual. How do you have so may smites? Do people hate the truth that much?

Looking further through this :

http://learn.usa.canon.com/app/pdfs/white_papers/EOS_C300_Sensitometric_Characteristics_WP.pdf

It appears that the camera is capable of parallel outboard recording over a 10-bit carrier (if desired). Does this mean 10-bit is just a firmware upgrade away?

Codec, SHmodec. What i see from the C300 on the screen compared to RED makes it look worth it. I just saw Girl With the Dragon Tattoo, and was again reminded how muddy the RED makes images look.  I can always tell when a commercial was shot with a RED, and that's not a good thing.  Right now, it looks like the c300 is best thing available for the price, so.....

Could someone explain why they didn't go for a larger sensor that maintains the 1.78 aspect ratio, but would still be compatible with their lenses? For example why not a 35X20mm sensor?

It seems like the industry has settled on this size (super-35) why?

Here's how i calculate 10 bit uncompressed @ 24p. I could totally be wrong, someone please correct me if I am.

1080*1920*24p*(10bit)=(447Mbs)

8 bits per byte so.

(447/8)=49MBs

Either way, it's a beast.

130MBs. Surely you must mean 130Mbs. Even if the recorder can handle 130MBs, there is no way that camera can output that much, is there?

I'm thinking uncompressed 4:4:4 vs 4:2:2  means 4x35Mbs=140Mbs max.

Anyone know the bitrate on the Sony with S-Log?

All in all a useless article. I'm not sure there has ever been a more boring test, ever.  At least choose a test scene with some color and more gradation.

I told my wife I wanted a c300, and she replied, " you mean that shitty movie with Gerard Butler?".

I thought bits were determined by the number of byes of information stored by each pixel. But I'm a hack so...

Great article here on the Scarlet and some pretty ugly truths about the camera

http://philipbloom.net/2011/11/20/scarlet/

That is no lie. This is a great article. Read it if you are on the fence about RED.

If someone had showed me this thrown into a random flickr account of someones ametuer photography I wouldn't have blinked an eye.  Rich people are assholes and must be stopped at all costs.

Hey if it wasn't for rich people and their "superior" taste, we'd never have known who Picasso was (see Gertrude Stein).  By this i mean, if it wasn't for rich people, recklessly bidding up the price of essentially worthless objects, there'd be no market for so called art.  So thanks to them, even hacks like me can hope to score it big, if all I have to do is impress a lonely, nursing-home heiress.   :P
