On the Broadswords, it looks like they have their Cutter drives running as well as their own. That certainly could happen the way they are setup, but it doesn't seem like what would usually be done.
For me, it is easier to watch a bunch of text, and then have the pictures (or vice versa) rather than interspersed.
In CT the SDBs and Broadswords would probably be using triple-turrets rather than single-turrets. Are you thinking in TNE terms?
When the SDB launches the missiles, I see a brief flash from the drive moving past a gap in the panel that opens above the missiles. This adds to the realism of the movie since this is what I would expect.
