New GH4 Firmware Update

New firmware for GH4 gives you still photos from 4K footage etc. http://panasonic.jp/support/global/cs/dsc/download/fts/index.html

I read that but don't understand what its doing. Is it extracting frames while you are shooting?

I extract frames that I really like while editing in After Effects. Would the firmware make that one less step?

I think so only at 25p & 30ps not 24p, loop recording??
