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?
