In that view you've uploaded you are looking at approximately 12 frames - half a second - of timeline. Are you sure that's not the problem?
Ah I see ok thank you! However I have another problem ... I'm trying to curve the graph here but it doesn't come up with the round handles you can do this with? I can pretty much zoom in all I want but it's not giving anything. I want to make the transition smooth so that theres no black background shown when I switch between clips. Thanks!
nvm, problem solved, just used seperate dimensions
