I posted. 2 examples taken from the same position. Lenses 18-55mm at 35mm on XT1 and 16-55mm at 35mm on XH1. Everything else on auto on both cameras.

Hi Alexei,
I watched the videos and two things are obvious. First as others mentionned, the optical stabilization of the 18-55 makes a world of difference. A huge part of the jerkiness in the H1 video is absent from the T1, thanks to that lense.
The second big thing is that the X-T1 treatment of the image has less dynamic range which makes for a more natural looking image in this low dynamic range setting (the books). The blacks are black and the whites are white.
On the H1 footage however, the "auto" settings allow for more dynamic range. If there was a bigger difference between the dark parts of the image and the bright parts, they could be recorded with no crushed blacks and less blown highlights. But in this case, the subject having low dynamic range, you get a flat looking image. The black are dark grey and the highlights are not so bright. A little bit of color grading would allow you to get the exact image that you would like.
Of course, these settings can be changed on the X-H1. You can decide to make the shadows darker before you shoot and make the highlights brighter too. It's up to you. On the X-T1, I'm not sure, but I think you can't do that, unless you choose a different film simulation. To get low contrast for example, you would use Proneg high or Proneg standard.
Have fun!
