Clarification on Timeline Start Value: Floating-Point Support and Alignment Behavior

[RIPTIDE-007]

Does the timeline start value in ShotTower support floating-point values, or are they rounded off internally? Additionally, if the start value isn't aligned with the end of the previous asset's duration, could this lead to inconsistencies or unexpected behavior?

Also I need to know whether the current version supports multiple video composition(overlay on top of another)?
