How are you trying to report on the video performance, and what do you want to report on, more specifically? There are performance reports at the page level, but you can also report on media views in a custom report (see the last part of this knowledge base article).
In the reports, you can add dimensions like count of media plays, media name, duration, folder path, object create date and time, and other similar.
You can also filter on all these data points, i.e., filter the report for a specific folder path. Does this help?
