That’s actually a pretty good way to do it. I did some experimenting and here’s the method I used. Made another copy of the girl and locked the comp viewer. Double-clicked the layer to open the layer viewer. Since there already is a full alpha, I figured, erase and invert. Click the erase brush and in the paint panel for channels, choose RGBA.
Looking in the comp viewer, I went to a frame that needed more glowing cord and erased it, set a keyframe for path and then went to the end of the comp AND DRAGGED the paint layer that’s created in the effect all the way back to the keyframe(wish there was a short cut for this_cause you have to do it for every new erase layer you make). “Page down” and needed to erase some more(the erase layer automatically extended each time I made a new stroke, that was a bonus)—did that until I was good. Went a few more frames, saw I needed to fix more, so I clicked off of the “erase 1” and started the process over. I only did a couple of seconds, but it’s pretty quick and easy to do it this way.
Then I added an invert effect, levels to pop it more(I actually did this last, but it’s third in the layer stack, I saw it needed it after I applied your blur and glow.) then blur and glow. I think it looks pretty good and natural(well natural for a girl dancing with a glowing radio-active iPod).
