Tracking Runtimes of videos

We produce videos for clients of varying runtimes. I have been trying to figure out how to best input these runtimes into a column so I can get a total. We need to track minutes and seconds which makes the math slightly more difficult. I ideally don’t want to have to use a formula column as those columns sometimes can’t be used effectively in automations and dashboards (although I haven’t actually tried with this use case).

Thanks in advance.
