We don’t have the duration parameter on the video object itself, so what you can do is get it from the video status API https://docs.api.video/reference/get-video-status. We have the duration in the metadata object.

The duration will be provided in minutes or seconds.
​
Another option if you are using the playerSDK is to use the getDuration() method.

You can find it here: https://github.com/apivideo/api.video-player-sdk#getdurationcallback-duration-number--void-promisenumber.
