[Kell Smith] “I am used to dragging a clip into the timeline, cutting it up, and making my choices from there. It’s an easy way to get rid of the garbage by just dragging it to the end of the timeline, or deleting the clips”
I don’t do this personally, but you can do this in Avid with a little trick. Just drop a garbage clip or a title at the end of your sequence and insert a bunch of filler, way more than your intended sequence length (source monitor menu) before it. Now you have a lot of empty space to play with.
