Red.com has a tutorial on understanding temporal aliasing:
[Temporal] aliasing can occur in time as well as in space. Perhaps the most common example is when a wheel or propeller appears to rotate more slowly or in the opposite direction:
This can happen more generally whenever the frame rate is less than twice the object’s rate of rotation or repetition. For example, if one photographed a clock less frequently than every thirty minutes, the minute hand might appear to rotate counterclockwise.
Other times, imagery of electronic displays may flicker or appear partially illuminated, and strobes may flash at irregular frequencies. All of these can greatly complicate and reduce the quality of a shoot.
Of course, Red doesn’t have a general solution everyone can use, but it has one for its own cameras, the Red Motion Mount:
The RED MOTION MOUNT can act as a soft global shutter by using a special filter that globally modulates when and how much light reaches the sensor. It’s fully electronic, lies between the sensor and the rear of the lens, and effectively functions as a single pixel liquid crystal screen that controls incoming light. In many ways, one can think of this as a temporal low-pass filter (TLPF), but its benefits extend beyond that.
Ultimately though, a soft global shutter pushes the limits of what is possible with motion capture, and effectively overcomes many of the traditional trade-offs. Cinematographers ordinarily have to choose between using a lower shutter angle and achieving sharper stills, for example, or using a higher shutter angle and achieving smoother motion. A soft global shutter can achieve both simultaneously.
The end result is a more natural and robust representation of motion that makes the most of a given frame rate. Everything else being equal, panning and motion blur will therefore appear smoother. Flickering from electronic displays and artificial lighting will be reduced or eliminated. Cyclical motion will be represented more accurately. Strobes and flashes will be less likely to depict partial or irregular illumination. Most importantly, all this can be achieved using the same camera, lenses and media as before.
