Tool to add and export bookmark to video

Hi, i need help with a certain tool:
I have a footage of 12 hours, where I need to mark every place a car passes on a video (i am ready to do that manually). Then i need to export the times where the marks occur into a csv or similar to make an analysis on that.

Is there any software making something like that possible?

Thanks & apologies if I added this into the wrong section
