Allow us to re-render a webinar session video

In the post-webinar video rendering of a session we hosted recently, the speaker's audio and video match up fairly well, but the slide transitions lag behind anywhere from 8 seconds to 24 seconds.  Meaning the presenter has asked to move to the next slide and 8 - 24 seconds later, the slide actually switches on the video. 

Support let me know there is no way they can re-render our webinar to see if the slide transition is more accurate, so I am adding it here as a suggestion.
