You could just add an On Mouse Click action to the containing element. If you are using HTML you could probably also just surround it in an <a> tag. However note that this might not be advisable because users often do want to interact with videos, although it seems like you are removing controls.
To expand on this, also note that a lot browsers nowadays enforce that video cannot autoplay unless it muted first. Mouse over isn’t an action that allows unmuting in this case, the user must click on the video. Further, mouse over/out aren’t really a thing on touch screen devices, so that’s something else to consider in the interface.
