Video overview

The E-M1X has some nice video features and some of the best stabilization in the business, but its capabilities mainly match the E-M1 II, leaving it look a little off the pace.

Key Takeaways:

  • E-M1X can shoot DCI 4K video at up to 24p / 237Mbps
  • Can shoot 1080/120 and output as slow-motion footage between 60 and 24p
  • Already impressive sensor-shift stabilization can be supported by digital stabilization at the cost of a slight crop
  • Gains Log capability (with LUT promised) but only 8-bit capture and output

Video capabilities

To an extent, the E-M1X's movie specs are a little disappointing. Despite being able to read out its sensor fast enough to shoot full-res images at 60 frames per second, it cannot produce 60p video shot from a smaller 16:9 or ~17:9 region.

Instead, like the E-M1 II, it can shoot UHD 4K footage at 30, 25 and 24p at up to 102Mbps or the wider DCI 4K format at 24p at up to 237Mbps. It becomes the first Olympus camera to offer Log capture, and the company says there will be a LUT to covert this OM-Log400 footage in popular editing software.

The E-M1X can shoot 1080 footage at up to 60p (52Mbps) or 30p and slower with All-I compression (202Mbps). Then, for slow-mo work the E-M1X can shoot 1080 footage at 120fps, which it then outputs as 60 or 50p footage at 50Mbps or 30, 25 or 24p at 26Mbps (ie around 100 megabits per captured second).

Screengrab from a DCI 4K clip. With so much black in the scene, this particular clip only took 33Mbps to capture it.

However, while it can output a 4:2:2 color signal over HDMI, it can't record or output a 10-bit signal, an increasingly common feature that would make its Log footage much more flexible in post-processing.

This is a bit of a shame, since Olympus has put a fair amount of effort into making the camera pleasant to use with an external recorder: offering a cable retaining clip and socket protector to prevent the HDMI lead working loose, and creating a clever mode that gives a magnified view on the camera while outputting a full signal to the recorder.

The company has also provided a 1/24th and 1/48th second shutter speeds to allow shooting at 24p with a 180 and 90 degree shutter angles.

What the E-M1X can do, though, it offer hugely effectively image stabilization for in-camera capture. There's a choice of sensor-only IS (M-IS 2), which lets you shoot using the full width of the sensor, or a more effective sensor+Digital IS mode (M-IS 1) that imposes around a 1.18x crop. The DPReviewTV episode was shot in the sensor-only mode, to give you some idea of how effective it is.

Movie autofocus with tracking is also available, with the ability to tune the tracking behavior.
