@ IgorC:

Obviously you don't understand the main difference between still image compression and video compression.

Motion prediction and inter-frame encoding.

One single image has no motion. No surprise there is less redundancy to spare. If you compared I-frame only MPEG-2 with I-frame only HEVC, the ratio would be similarly disappointing.
