Hi, I'm kinda new in the editing and i have a problem. So now I'm editing short film for my classes and on timeline i have a lot of cut clips i wanted to make a composite shot for one of them but when i clicked 'make composite shot' my clip went black. When I was in the composite shot and clicked play there was just black screen. When i went back to my timeline this clip was black there too. I don't know if i described everything correctly but like i said I'm not super good in editing. Someone please help me, please.
