Doorbell 2 Incremental Footage

Hello,So I was looking at my doorbell footage and I notice it was in increments, is there a way to find the footage between the increments? For example I have a shot at 8:52:40AM and then 8:52:58AM, but I would like to see what was between because there was something stolen between those times. Please let me know if you all know of any way to request this or if it is a lost cause.
