Well yes and no. There is the case with fixed frame rate, then ES and container should match. Then when a video is missing frames the duration a picture might be displayed is a multiple of a picture 'tick's, this is also the case when there are transmission errors. Last case is totally variable frame rate, then timing should just be in the container.
