A little knowledge is more often than not more dangerous than no knowledge.
Stills taken from videos I have taken are quite poor in comparison, especially when I am on my bike. I tried to capture a screenshot of a car registration that was behaving dangerously on the road, the only way I could record it was be watching the video repeatedly (I only got a quick glance at it) as it was too blurry on the extracted photo.
Yes, I understand that I probably wouldn't have captured the photo at the right tiem anyhow if it was taking photos at intervals, the point above is just to highlight how poor the quality is in comparison.
