Add cues

Now add a jingle on cue 3, don’t put it in a loop, only play it once.
Add a fade in

Add a looped video on cue 4. Now let’s set an automatic sequence between cue 3 and cue 4, you can do it with a Wait by calculating the duration of the jingle or just by using the Follow mode which allows an automatic sequence while taking the fade in time into account .
