While Fujifilm is able to slap the '4K' label on the X-T100's box, you might as well consider this feature to be an 15 fps, 8 Megapixel burst mode, as video is incredibly choppy and rolling shutter strong. Users are more likely to use the 1080/60p setting, and both 24p and 23.98p options are available as well. Starting video recording requires holding the red button down for nearly a second, which can cause you to miss a moment.

Key takeways:

  • The X-T100 is a poor choice for video with uncompetitive 4K and 1080p capture
  • The base ISO in movie mode is 400; Auto ISO is available but exposure compensation cannot be used in manual mode
  • There's a socket for an external mic for better audio quality; Manual audio level controls are available

We've established that the X-T100 has no serious 4K video capability, though it does advantage of 4K in other ways, such as for the Multi Focus and Burst features mentioned earlier.

That makes the X-T100 a 1080p camera but, as you'll see below, not a great one. There's no focal length crop here, regardless of the electronic IS setting. The ~37Mbps bitrate isn't terribly high, but it's the processing that's the source of the X-T100's poor video quality.

For reasons that are unclear, the base ISO in movie mode is 400. Auto ISO can be used in all modes, though the camera doesn't display what the current sensitivity is. You can use Auto ISO in manual exposure mode, but exposure compensation cannot be adjusted.


There are few video-making controls on the X-T100. You can adjust exposure, focus mode and audio levels, but that's about it. While the camera supports focus peaking, it turns off as soon as you start recording a video. A zebra pattern highlights warning isn't offered, though the X-T100's audience probably won't be too concerned about that.

The X-T100 does support clean HDMI out, though you can't record to the memory card at the same time.

Video Quality

As we hinted at before, video quality on the X-T100 is poor, whether at 4K or 1080p. The X-T20 shows us that Fujifilm can make a relatively inexpensive camera that takes good 4K video, and it's worth stepping up to it if you're even a mild videophile.
