One of the details from the article is that using anamorphic lenses essentially treats the camera sensor as if it is larger than it actually is, which reduces the effective depth of field.

If you look carefully at the backgrounds in Mandalorian scenes, a lot of the time, they are slightly soft (out of focus)--which hides the pitch of the LED wall by expanding each LED point into larger, overlapping circles of confusion. To be clear, that softness is a physical effect of the camera lens, not a digital effect on the wall, so it can be captured by the camera sensor up to any resolution you want.

> Also, how do they cope with the scan rate of the background video being played back to sync with the camera recording the footage?

In the article they say the latency is about half a frame, which they handled by using slow camera moves--which conveniently is similar to how the original Star Wars films were shot.

If you're talking about the refresh rate of the LEDs, I believe those can be cranked up way higher than the frame rate of the camera, which was likely 24 or maybe 30 frames per second to give that cinematic feel.
