I'm trying to use Blender as my primary video editor, I love the concept of imposing 3d onto videos and also being able to add effects and color correction, etc. My problem is the workflow. I have a video with audio, I need to crop it, color correct and add text. In order to crop, I need VSE, in order to color correct, I need nodes, then I need VSE + 3D viewer for text. I don't understand how to use all of those tools without multiple renders. Right now, I crop the video, render, bring it into nodes, color correct and move from there. But soon as I import into the node editor I lose sound. I know this is probably just an ordering sort of issue or there's an obvious missing piece, but I can't figure out what it is.
To put my question succinctly:
How do I use all of Blender's video editing tools AND maintain audio without multiple renders?
