So I have a video fully edited and am trying to add effects to the final product. Every other effect I have previewed has worked but for some reason the "Aged Film' effect which is the only one I need shows black in the preview screen and if I add it to the clip then blacks out the entire clip. So far it has only worked on ONE clip out of about 15. Not sure why this is happening.
I have tried restarting, resaving, exporting the project and starting an entirely new project, I can't seem to understand why it hates that effect so much! Any help would be very appreciated!
