I think most users would think that when you have the checkbox checked in it would the oldest video if storage exceeds 90%.
Then if they enter 300gb and 5 days they would delete old videos if it exceeds 90% storage, exceeds 300gb or is older than 5 days. This is not the case.
Now the storage space and days option is only active if the checkbox is NOT checked.
