Hello,
I`m new to this forum, but a long term reader, because it is the best forum for information about NX1 (which I own).
The Fuji got my interest for its pleasing colours.
I downloaded two original files from http://www.dkamera.de/news/preview-beispielaufnahmen-der-fujifilm-x-t2/
and discovered, that the codec implemantation may not be very good.
It uses a "High L5.1" variation of mp4 at 102 Mbps with no CABAC and no B-frames unlike for example Sony RX100IV etc.
One I-frame followed by 30 P-frames according to mediainfo and avidemux.
Just like smartphones, but at a higher bitrate.
