Hi this is my first time posting in a forum so excuse any noobness that spews out here. But here goes.
So I edited a project where I had all the rushes saved onto my macbook. I was running out of memory on my mac so upon completion I decided to save the entire project onto my hard drive, scratch disks, rushes and sounds everything was all put onto the hard drive.
I have just booted up the project from my hard drive and it made me reconnect all the rushes to the correct file location of my hard drive. So I reconnected them all, I then had to render the whole project and upon the completion of the render now all the clips on my timeline need reconnecting still.
You may need to select the offline media in your timeline, right click and choose reconnect media.. Yes you have to go through the reconnection process. Seems odd i know but I've had this issue before where I've re linked media in the project, but it didnt ripple into the associated sequences. Try a few clips first, but it should work.
