Just a little drive by follow up to my Post about Multichannel Secondaries. At the start of that video I showed a quick way to extend a clip to connect it to a Primary that it doesn’t overlap. Then, before finishing that topic, I went off on a wild tangent. 🙂 Here’s a quick video that finishes that trick. 2.5 minutes of fun!
Update: This also works for clips that start after the primary clip you’d like to connect to, though it will move the clip so you’ll need to reposition it. Still quicker than other workarounds… Also, I’ve come up with a silly name for this process. “Panhandling”.
usage: “Just stick a panhandle on that clip and you’re good to go” lol

Just found this tutorial. Wow! Just wow! Thanks for this tip. Gonna use it on my next project to organize all sfx, music etc. audio stuff to their own storylines.
