Video Project

Hello

I am planning to make a Music Video. I have a mastered audio track (Song) ready.
I want to make some clips i.e. playing an instrument and having the song play in the background.
Then I want to merge the video with the mastered audio track. Matching the audio
hitpoints with the video will be a challenge to ensure it will fully aligned.

I understand Cubase 10 Pro does not have a Video export function.

How would you do this ? Any suggestion on the right software to use ?

I have iMovie but have some real difficulties to get used to it…

Thanks for any hint you could give me.

Jo.
