  1. Fuji never said 17ms, that came from nowhere, the official press release claims rolling shutter has been halved from X-T2/H1. Also simple math, 60fps is approx 16ms per frame, so rolling shutter cannot exceed that.
  2. X-T2 does not offer a setting to turn off noise reduction in video (default at 0, greyed out), X-H1 and X-T3 allow you to turn it off completely using "-4",
  3. The 17ms quote cannot be found in any of the official Fuji press releases, DPReview mentioned "16ms" in a preview article but no source given. Interestingly, Fuji's official X-T3 press release claims that the rolling shutter distortion "has been halved" compared to X-T2 and X-H1, which has a 21ms rolling shutter according Cinema5D lab test, X-T3's 9ms test result aligns nicely with this official statement and Cinema5D's consistent testing setup.
  4. The only reason is that none of the current ARM processors support HEVC Main 10 version 2 (which includes 10bit 422 up to 12bit 444)
  5. Current ARM processors can only handle hardware accelerated HEVC Main 10 Version 1 up to 10bit 420, to get 10bit 422 or even higher (12bit and/or 444) you need version 2 which is not yet widely supported.

    8K refers to hardware accelerated encoding, downsampling is almost always a computationally intensive CPU task. If you look at the readout modes listed on the IMX183 page, 2.7K readout is pixel-binned, it's then upscaled to 4K in the FOV mode. I don't think it's the sensor that's prone to overheat, it's the processor since it's not capable of hardware accelerated 5K downsampling (Sony's BIONZ chip was purpose built for this).
  7. Alexa is under 5ms, otherwise the highest framerate 200fps wouldn't be possible.
  8. Ha, I've done my research, The bitrate Fuji implements at 200Mbps and 400Mbps exceeds the maximum for hardware acceleration (for now).
  9. Right now the internal HEVC Main 10 Level 5.1 10bit files are extremely taxing on even the most high end hardware. Maybe Adobe CC 2019 with improved playback acceleration could make things a bit better, but for now if you really want 10bit, external recording is almost a must!
  10. With preproduction firmware, the performance looks on par if not better than Sony: With Fuji's Kaizen philosophy it can only getter better from now.
  11. Sony can't do eye AF in video mode.
  12. It does not reduce the dynamic range of the scene, it simply makes the black level "milky". You can take away light from a scene, for example using ND filter, but you cannot add light to the shadow with just a filter.
  13. You can format card externally as exFAT and use it in camera, but the video files will still be split into 4GB chunks.
  14. This tool does exactly what you want, Panasonic Vlog to LC709A: http://cameramanben.github.io/LUTCalc/LUTCalc/index.html
