Jinni.Tech Part 6 – REDCODE = QuickTime? A Complete Guide to REDCODE & CineForm – Cinema Camera RAW recording

After an extended absence of virtually 3 years, Jinni.Tech is again on YouTube and he has posted Half 5 and Half 6 of his look into RED. Half 6 is titled REDCODE = QuickTime? A Full Information to REDCODE & CineForm – Cinema Digicam RAW recording.

In case you are not conversant in Jinni.Tech, it’s the YouTube channel of Jinni Know-how Ltd., which makes the Jinnimag, a variety of RED MINI-MAG® Suitable media choices.

On this newest episode on YouTube, Jinni.Tech discusses what’s inside a REDCODE .r3d file? Can it’s seen immediately like a QuickTime video? And why does it want RED’s particular gamers?

This video explains the important thing claims of the RED patent claims and compares it with the CineForm RAW, and earlier (although not patented) wavelet RAW codec.

I encourage anybody who’s within the subject to do their very own analysis and take a look at either side of the story. This video is simply based mostly on one particular person’s analysis and opinions.

Jinni.Tech additionally posted just a few notes, corrections, and clarifications:

• 9-7 seen within the JPEG2000 isn’t a bit divisor between excessive and low cross. That’s the variety of coefficients within the FIR filter and is irrelevant to the bits used. Nonetheless, 9-7 requires twice as a lot operation as 2-6 within the CineForm adaptation. That’s because of the CineForm codec goals to cut back the compute.
• RED’s inexperienced averaging is extra CPU intensive than CineForm’s. Nonetheless, apparently, the softness within the RED’s footage is because of 2 elements: the blur utilized to the output; and their poor demosaicing algorithm.
• The “pre-emphasis” curve in RED’s patent is the inferior gamma curve and never a greater log curve, thus the RED one’s poor efficiency within the shadows.
• Evidently within the early editions of the RED One digicam, RED didn’t do something to the RED shade.

There are at all times two sides to any story, however nonetheless, the video raises some fascinating factors. Nonetheless, on the finish of the day, RED was granted a patent, and no matter how chances are you’ll really feel about it, they have been good sufficient to get it issued. As soon as any firm has a patent, it is going to legally defend any actions taken by competing firms that intend to make use of that expertise. That’s simply enterprise and it occurs throughout all industries.
