using soundbooth for editing
Soundbooth allows a user to edit both sound and video, which is useful if you want to specifically edit audio in a detailed way. Plus, you are probably more familar with Soundbooth at this point.
Go to File>Open and open your premiere video
The video will open up in the lower left hand corner of the screen. To enlarge, left click and click on “maximize.”
If you don’t want to see your video full screen, leave the thumbnail where it is and continue to edit sound regularly in Soundbooth. If you’d rather edit the sound in full screen, you can go to effects or processes just like you would with a track. Or, you can exit out of it completely and ONLY work on sound which I find less distracting.
In Soundbooth you can split or make tracks that will later show up in Premiere. The nice thing about doing this is that Soundbooth will open videos in their raw format, (right after imported onto your desktop) in premiere, quicktime format, etc. Therefore, this is useful when importing clips for use in your video that you didn’t get from the same camera or source.
