Linking vs. Embeding Video

Hello all,

I would just like some pointers on linking Quicktime files through paths verses embedding them. From just trying it out, when I link the video footage from the main directory path, it won’t show up in the export tester. However, when I embed the video, it shows up, but the file is very large, so it takes a while for the export loader to finish loading in order for me to view it. I am having different types of issues relating to this. Can anyone help me out?
