Some perspectives for you.

It looks that the motion effect you mentioned is to interpolate frames for the low frame rate video (e.g. below 30 fps) to a higher rate (e.g. 60 fps) for improving the playback smoothness (if there are many motion scenes in the video).

For conventional movie videos that are mostly in 24 or 30 fps, I don't think the effect can be unlimited to increase the frames to 100 fps to be consistent with your LCD.

If you expect that the frame interpolation would give you better video quality or playback smoothness, the excessive interpolation would only produce more fabricated frames, and make things worse if the original video is not produced with high fps natively.

A high refresh rate monitor (> 60 Hz) might be great to use with gaming or 3D playback, but for normal 2D movies, not exactly.

For the action videos that are recorded with 120 fps or above, I think the frame interpolation is trivial.

Hi,
I thought it would be something like svp or DmitriRender which can virtually increase the frame to your monitor's frame rate. So what is TrueTheater for exactly?

Per this page: https://www.cyberlink.com/stat/technology/enu/tech_vid.jsp
TrueTheater motion can increase the frames to 72 fps as maxmium.

Theorectically, to avoid flicker, I think the detail should be like this:
For a 30 fps video -> It is up to 60 fps.
For a 24 fps video -> It is up to 72 fps.
