Media Manager allows you to attach "Analytics Tags" when embedding your videos. You can use the Media Manager Query builder to access videos tagged with those Analytics tags.
First start by adding a new Condition.
The query will be extended with more information.
We need to change the field to be our Analytic Tag. We can do this by selecting the first item in the condition (in this case Title). You will be presented with dropdown.
Now we select "Analytic Tag". Now the query will update. We can now type the name of the analytic tag we want to query for.
So in this case we want to search for all videos that are tagged with a certain "uid". So we need to set the value after the IS to finish the condition. Once we press enter the query will run and the data will update.
This allows you to filter down your Analytics based on your own meta data.
