This script is for only video files that are 24fps sources such as movies and animations and are saved at 24fps.
In other cases, for example, if the 24fps source is saved at 30fps, it will be laggy.

Try the following. You should be satisfied.
It will be as smooth as DaVinci Resolve. If you use the following, you don't need to use DaVinci Resolve anymore.

Open %APPDATA%\SVP4 with the Windows key and 'R' key on the keyboard, open override.js with the text editor, copy and paste the following text between /***** INSERT BELOW THIS LINE *****/ and /***** INSERT ABOVE THIS LINE *****/ in override.js, and save it by overwriting.
