First REDCODE image!

We decided to push REDCODE to it's limits today. This is NOT the REDCODE you will get with the camera. That will be about 10-12x RAW compression. This pic is REDCODE with 100x compression! It was recorded as a 556k file! This shot is a frame grab from a 24fps stream (1/48th sec) using the RED 300mm at 4.9K, cropped to 4k, compressed with REDCODE 100 (NOT available except for testing), then scaled to 1k and jpeg compressed to 8 bit.

That is really really really incredible. RAW-Milk, RAW-Image AND RED lipps in this compression and quality. That must be a swiss cows milk ;-))
 
100x compression doesnt look so bad does it :)

Pretty impressive when 4k Redcode looks better at half the bitrate as HDV at 1080i.
 
Okay, I'm going to admit to being ignorant and not being sure I understand you fully. All the numbers with "k"s next to them have thrown me, plus I'm still trying to wrap my brain around RAW.

You're saying that this image is somewhere in the ballpark of ten times more compressed than what will actually be derived from the camera?

I'm pretty sure that's what you said, but I'm confusing 10x-12x RAW with 10bit-12bit and so I want to make sure I'm getting it right.
 
Compressing the file almost 10 times more than normal REDCODE RAW, scaling it down to 1k, then also compressing it to JPEG - and it still looks that good! Saweeeeeet....

What nobody has mentioned yet is the performance of the 300mm lens in this shot. Being one of the reservers of the 300mm, I'm really liking its results, even after the imaged has been compressed, scaled, and transcoded to the max. I had planned to use the 300mm usually for sports, nature, etc., but certain narrative cinema and commercial shots are looking like a distinct reality for it.

It sure looks like RED's statements that most users will want to shoot REDCODE RAW 4k may indeed be the case...

Niiiiiiiiiiiiiiiice!
 
INSANE. 100 percent compression....speechless

just realized..this is our first sneak peek of what the red 300mm lens can do!..wow

Just to clarify (please guys, tell me if I'm wrong):

Frame dimension in pixel:
Originally shot at 4.9K, cropped to 4K (4520x2540) and then converted to 1K (1024x576).

Compression/codec
Shot using Redcode100 (result a file size of 556k - frame dimension in kbyte), converted to JPG (I think max quality)

Bit depht
Originally shot at 10bit log, converted to 8bit

Note:
The bitrate (when shooted) for a 4K-10bitlog-24fps stream is LESS than HDV. It's correct? wow.

No worries it gets confusing fast :)

Shooting compressed on camera Red is targeting around a 10:1 compression ratio, for nearly lossless recording at the full 4k.

4k for Red is not the DCP spec of 4096x2160, but 4096x2304. Red also shoots 4.5k, which is 4520x2540, and even better the effective area of the sensor is 4900x2580 lines (which is what the camera is being shot at for all these tests)

Anyways, normally a RGB Tiff at 4.9k is around 70mb per frame. 4k is around 55mb, hence going from 55mb per frame to 550kb per frame Redcode is a 100:1 compression ratio, something that Red never intended on going down to, but was required to for application testing today.

As you can see, the results are pretty incredible, if not completely shocking.
 
These are stunning results! Certainly makes me believe that 10x Redcode compression is good enough for pretty much anything.
 
I hope Joanne and Kelley left a lot of paper in the RED fax machine...9 more minutes to go on the reservation deadline.
