Organization of storage of video archive of lectures with exact tagging?

Question

Video

There is a task - the organization of a video archive of lectures of several hundred hours. I would like to create a directory with a hierarchical tag system with the ability to refer to a specific time in a video file. Highly desirable with network access. The file format is avi, but this is not important - you can also recode it. While searching for solutions on the network did not bring anything. Has anyone had a similar problem and do you have any recommendations or advice?
