My daughter is making a tutorial art video for school.  Parts of it she intentionally sped up so it wouldn't be so long.  She had it all ready to go & then decided to add music. 

She chose forgot that it would sync the video to the music's beat, unless you deselected that option.  When it did that, the editor cut 7 minutes from the video without her choosing. 

Now she has the music removed, but cannot get those 7 minutes back.  

I do believe she did NOT save the video before this began, sadly. 

Is there any way to get those 7 minutes back? 

Please help!  It's of course due tonight at midnight!!!!
