Can the video be played when the music is playing only

[Nader Kamel]

Hi guys .
1. Can the video be played when the music is playing only ... and end when the music is closed ..
Knowing that I play Bpm ?
2. Why IR Clip SA works with the first video in the first layer only ?
3- How to the automatic bpm in live event ?
thanks a lot
