This creates uneven motion, appearing stroboscopic. Other conversions have similar uneven frame doubling. Newer video standards support 120, 240, or 300 frames per second, so frames can be evenly sampled for standard frame rates such as 24, 48 and 60 FPS film or 25, 30, 50 or 60 FPS video.
For example, a TV running at 120 Hz and displaying 24 FPS content will simply display each content frame for five of the 120 display frames per second. This has no effect on the picture other than eliminating the need for 3:2 pulldown and thus film judder as a matter of course (since 120 is evenly divisible by 24).
Filmmakers may originate their projects at 120, 240 or 300 fps so that it may be evenly pulled down to various multiple differing frame rates for distribution, such as 25, 30, 50, and 60 fps for video and 24, 48 or 60 fps for cinematic theater. The same is also done when creating slow motion sequences and is sometimes referred to as "overcranking."

GoPro, Sony and other action camera competitors record video at 1080p and 2.7k at 120 fps, 720p and 1080p at 240 fps, and 4k at 60 fps. Although the video formats were designed for slowing down in post-production, the cameras generally record very high frame rates [ 7 ] in high definition with generally clear audio.

Smartwatches are a hot-ticket gift over the holidays, but a new study might have you rethink how you strap the device to your wrist in the future.
In the case of filmed material, as 120 is an even multiple of 24, it is possible to present a 24 fps sequence without judder on a well-designed 120 Hz display (i.e., so-called 5-5 pulldown). If the 120 Hz rate is produced by frame-doubling a 60 fps 3:2 pulldown signal, the uneven motion could still be visible (i.e., so-called 6-4 pulldown).
