Image encoder/viewer using h264 I algorithm?

[shae]

I read somewhere here that h.264's I-frames are encoded more efficiently than JPEG. Does anyone know of an image encoder/viewer that uses that (a plugin for a common viewer or Photoshop, or even commandline)?

It's really surprising that no one has come up with a more advanced lossy still image compression format in 15 years. (JPEG2K isn't better generally, but maybe something will come up eventually of JPEG XR.)

You can open mp4/h264 with photoshop. At least with extended one. Also x264 probably can do 1-frame movies.

I was hoping to find something that's really meant for use for still images.

Couldn't find any plugins. Can you recall its name?

Dump the frame into an MP4 container (via x264 directly) and they can be viewed with XnView (http://www.xnview.com/en/index.html) (Open Source) ...

I just did a bunch (using imagesource() in Avisynth for import into x264) ... I blantantly ripped off DS's settings (http://forum.doom9.org/showthread.php?p=1299596#post1299596) (while adding a --crf 18 tag) posted in that other thread (thread link now editted in) ...

My exact commandline looked like this:
x264 --crf 18 --frames 1 --8x8dct --trellis 2 --subme 9 --psy-rd 1.5:0.5 --aq-strength 1.2 --output "test.mp4" "test.avs"
