After a long absence of nearly three years, Jinni.Tech is back on YouTube. He posted Part 5 and Part 6 of his RED Thoughts. Part 6 is titled HE REDCODE = QuickTime?The Complete Guide to REDCODE and CineForm – Cinema Camera RAW Recording.
If you’re not familiar with Jinni.Tech, check out the YouTube channel of Jinni Technology Ltd., the creators of Jinnimag. Here are a variety of RED MINI-MAG® compatible media options.
In this latest episode on YouTube, Jinni.Tech explains the contents of the REDCODE .r3d file. Can it be viewed directly like a QuickTime video? And why would you need a specific player from RED?
In this video, we explain the main content of RED’s patent claims and compare it to CineForm RAW and previous (but not patented) wavelet RAW codecs.
Anyone interested in this topic is encouraged to do their own research and see both sides of the story.
Jinni.Tech also posted some notes, corrections and clarifications.
- The 9-7 seen in JPEG2000 is not a bit divisor between highpass and lowpass. This is the number of coefficients in the FIR filter and is independent of the bits used. However, in CineForm adaptation, 9-7 requires twice as many operations as 2-6. This is because the CineForm codec is intended to reduce computation.
- Green averaging in RED is more CPU intensive than CineForm. Clearly, however, the softness of RED’s footage is due to two factors. Blur applied to the output. and their poor demosaicing algorithm.
- RED’s patented “pre-emphasis” curve is a poor gamma curve, not a good logarithmic curve. Hence, his RED performance in the shadows is reduced.
- In the early editions of the RED One camera, RED seems to have done nothing with the RED color.
There are always two sides to any story, but the video nevertheless raises some interesting points. But in the end, RED got the patent, and regardless of how you feel about it, they were smart enough to issue it. Legally defend the actions of competitors who attempt to use technology. It’s just business and it happens in every industry.
