Scanning recorded video

Some pet owner left a undesire gift on my lawn.
It is an area not for detection.
It will be two day or more playing record.
Is there a tool in playing vids to check for change in a small square area ?

@cf7 If it’s a 24/7 camera…what I’ve done is scrolled back by the hour. As long as you see your donated “gift”…keep going back until it’s not there. Then you’ve narrowed it down. Then do it again in 15 min increments until you find the event you’re looking for.

Seems tedious, but it’s not too bad. If it happened a while ago, check by day until you narrow it down more…then go by hour, etc. I usually find what I’m looking for within 2-3 minutes. Good luck!!

Thx…
