I think the video is perfectly acceptable, even the vimeo compression.
Vimeo, being one of the most popular distribution formats, is what you need to prepare your output for, and it will create artifacts by default.
However, view this video on a phone next to Alexa, Epic, F65, etc etc footage...
View it on a tablet, view it on a plasma screen, and lcd, an old 4:3 tube, your computer monitor... watch it on a calibrated screen, on a screen with color presets, etc... realize, that we as media making professionals, may not have 100% control as to how our audience will view your motion picture, but we can get a great feel for the gambit it will run.
Naturally, we'd prefer the files straight off the camera, but the vimeo test gives us one circumstance that it can be viewed, however, we are going to view this on so many different screens, and on some the Vimeo compression is less an issue altogether.
Innovative camera, at least from a cost perspective.
I am interested in what the next gen model will have.
