FB Video Ads - View Duration

Was wondering if anyone has any data to validate if video ad viewership duration has any correlation to sales conversion.

Example:

Video ad duration is 30 seconds.

Rapid drop off is at 4 seconds.

if we somehow got the video do drop off later at 8 or 10 seconds, does it matter?

It depends what is the goal of the video, if it explains products and service.
Then the longer the video is watched, the person has more interests.
However this doesn’t mean that product will be bought right away.
