Why didn't JPEG2000 take off?
Patents & licensing cost + royalties
That HEVC based image format is pretty much the same FAIL, no one will adopt it because of the HEVC patent pools being greedy as fuck

jpeg2k is widely used in digital cinema distribution.
>>52347361
Original JPEG is also patent-encumbered.

Dare I ask why?
Parents make me sad

You bafoon.

Oh yes I meant patents

NOPE.AVI
All the patents filed in the 80s and 90s all expired

Nobody spells it with an asterisk.

An Asterix?

Only the arithmetic encoding of streams is (was) patented. Huffman coding was also an option, which was not - and that's why Huffman is all almost any JPEG implementation supports.

Well, MotionJPEG was a thing before even H.261, and I-frames were more convenient for editing. H.263 and H.264 were both a little too late, but the real "why" is something I don't understand myself.

Intel are still building it in, but several other SoCs are leaving it out. It's the two pools thing - and HEVC Advance charging per-distribution royalties - that will kill it. By the time anyone would consider widely using it, NetVC - the generation after HEVC - will render it obsolete like Opus has for AAC.

You still have .webp which no one uses that is better than jpeg/jpeg2k and also free.
sharing images over the internet works well with JPEG/PNG so JPEG2000 does not address any pain point since there isn't one.
GIF on the other hand was is shit for short videos which is why WebM took off.
What about FLIF?

JPEG2000 looks great at low quality, but most images on the internet can afford higher qualities and the advantage shrinks. In fact, at very high quality it flips and JPEG2000 ends up worse. The main problem is that the JPEG2000 wavelet and most encoders are optimized for PSNR, which tends to severely blur images. And yes, the patents, though I think they are now expired.

In 12bit XYZ color space. It's a really stupid format but disk space doesn't matter because digital movies are distributed by mailing hard drives. The rumor is that the weird file format would be harder to pirate.

>the rumor is that the weird file format would be harder to pirate.
The reason nobody pirates DCPs it's because they're encrypted. The decryption keys are sent hours before the movie is exhibited and the system won't decrypt the video unless the whole projection chain is considered "trusted".
