Do you mean to perform the Action after the video has finished, or to perform other Actions while the video is running, but still wait for the video to finish before going beyond a certain point in the ActionList?
For the former, just check Wait until finish? in your Engine: Play movie clip Action.
For the latter, begin your list of Actions with ActionList: Run in parallel, which allows you to create multiple "branches" of Actions that will run simultaneously. You could use this to create two branches - one that plays (and waits) for the video, and another to perform whatever other Actions you want to run at the same time.
To "sync up" both branches at a later point, you can then use the ActionList: Wait for preceding Action. This is a rarely-mentioned, but powerful Action that can be fed in the various branches made earlier - and will only continue the ActionList when both branches have been completed.
