I cannot figure out if there is a way to create a loop between two points in a video I can automatically replay.
Is this possible ?

I'm not aware of a video loop effect.

Workaround: render the wanted loop between in/out as a looped-gif and load the lopped-gif in the timeline.

Thank you for confirming that it is not a built i9n function.
Good solution you gave .. simple..go figure I didnt figure that out myself .
