Comparison isnt accurate

[Enelar]

JPEG is outdated. And its out of the league. Same with GIF.
Since you suggest new format, that not yet fully supported you have to compare with competitive alternatives:

• JPEG2000
• WebP
• FLIF (+ animation)
• WebM (animation)
• MP4 (animation)

Look what google did: https://developers.google.com/speed/webp/docs/webp_study?csw=1
Use PSNR / SSIM

Dont get me wrong, you publish closed source codec, compare it to previous century technologies, and expect we would adapt it. No way. x265 is great since it has intel(and probably amd) cores support, but. but. It weren't adopted by any browser, nor would be adopted(except probably Safari, cause they don't mind closed source). Meanwhile almost every end-user app nowdays either hybrid or pure web.
On other hand we have WebP, which already implemented in Chrome&Opera&Android + UC (74% of world traffic consumers), and on his way in Firefox&Safari team.

If you really want your work to be worthy, you have to put some effort to it. We have tens of image format alternatives, same as with compression algorithms.
