But it's not an automatic process in Premiere Elements. So you'll have to use some audio/visual cue to line things up.
overlay might be a better word than insert
Okay, they both have the same soundtrack (2 cameras, side by side, 1 wide angle ! close up shots). Can elements show both audio tracks, like a multitrack view?
Yes, in Expert Mode on the timeline.
What version of Premiere Elements are you using and on what computer operating system is it running?
Versions of Premiere Elements later than 10 have differently named workspaces. Version 10 has Timeline workspace and Sceneline workspace.
Timeline has the numbered video and audio tracks as well as Narration track and Soundtrack, Sceneline has the Filmstrip. In versions 11, 12, and 13 the counterpart workspaces are Expert workspace and Quick workspace.
As for your video and audio sync'ing of unlinked clips....at the Timeline track level some handy maneuvers....
a. select the clip, then hold down the Alt key and hit the left or right arrow key for a 1 frame nudge.
b. select the clip, then hold down the Shift+Alt and hit the left or right arrow key for a 5 frames nudges.
These "nudges" should work in versions of Premiere Elements before and after 10.
If you are using a Mac computer, then we need to translate the nudges in Mac. I am strictly an Elements Windows user, so
all I can offer on that is Alt Windows typically means Option Mac.
Please update us on your progress when you get a chance.
