Screen recorder audio edit - how to. Please help

In general, I think it would be good to have two tracks for the video editor: one for the video and one for the audio. One thing to consider, though. If you worked your screen recording actions to synch with your VO, editing the VO will have an impact on the synchronization. This means you'd have to have the ability to cut into the video to make multiple video events you could move on the timeline to synch with the edited audio.

This is the standard approach in any video editor, including Camtasia. But the video editor in Storyline only allows you trim the head and tail of the video. You can't slice out something in the middle and then re-align things. So you're only option is to do what Alphonso did: export the MP4, do the work in a video/audio editor, then bring the edited MP4 back into Storyline.

I produce my VO and screen recordings separately, and I make an audio file for each synched chunk. This way I can move the audio on the main timeline as necessary to get things to line up the way I want.  

I'd like to see the video "editor" in Storyline become an actual editor, at least as far as making cuts in the video instead of just trimming tops and tails.
