Any thoughts on my comments regarding the pacing of the cliff's edge scene?

Spalko threatens indy verbally in Russian as if she's fixing to kock him over the side, but then the chae goes on for several seconds before Mutt comes in. It would play better if that gap was smaller? Am I making any sense?

Also, is it common for edits to be done without sound first? Just the get the visuals done. Or is the audio and video usually done int tandem? I'm getting good with the video but I suck at the audio.
