Official site for BPG image format: http://bellard.org/bpg/
BPG (Better Portable Graphics) is a new image format that compresses more than JPEG and retains more details than JPEG
compression. Animated BPG is also supported. And this is what I'm testing. Animated BPG.
I did a test compression creating an animated BPG (animated GIF).
Source was a high def trailer for Mad Max Fury Road then trimmed+cropped+resized down to "avatar" dimensions (125x125).
It was processed and saved as a lossless RGB (UT Video Codec: ULRG) AVI file and then each frame exported to PNG (VirtualDub).
The PNG's will encoded sequentially to BPG encoder to create an animated BPG (gif).
The original video was: x264 / 1080p / YV12 / 4:2:0 / 8bit / mkv.
I used avisynth and "Dither_package" to downsize using highest quality settings in 16bit (stacked) processing.
Final output was converted for: ULRG / 125p / RGB / 4:4:4 / 8bit / avi.
The GIF was created by uploading the lossless RGB (ULRG) to gfycat (http://gfycat.com/SingleSmallFirecrest) and then downloading the GIF.

BPG uses HEVC encoder (jctvc x265).
I've not looked for other builds/mods where I can use different HEVC encoders.
I definitely have not tried a different build where I can encode with my own HEVC settings.
Right now, this is all preliminary testing to get used to the concept.
At a later date, I'll look into other builds where different HEVC encoders and custom settings are supported.
BPG version: BPG qp=21: 114 KB or 117,457 bytes

If you right-click over the BPG version, (Firefox) and go "View Image" (midde-click to open in new tab)...
You will get a PNG image instead of the BPG image.
Right-click on the GIF version, (Firefox) and go "View Image" (midde-click to open in new tab)...
You will get the GIF and will be able to download as an animated GIF.
