On the animated background package they import as 30 seconds long but I can’t drag to extend them to 5 minutes for example, am I doing something wrong?
Just fixed it. Right-click on the box-Delete files and redownload. It should be ~10 minutes now.
Thank you 
Just so you know when I import them they are 3 hours long not 10 minutes but I’m fine with just trimming it.
yea, it’s hard to guess what length someone would need, I decided to go all in
