Cutaways, cutaways, cutaways
One of the big problems with improvised dialogue and to a lesser extent improvised blocking, is the amount of footage you need to shoot in order to get a good pool of dialogue to work with while editing. And in order to actually use all the dialogue you want for a particular scene, you need quite a lot of both cutaways and dialogue shot from varying angles.
With B&C, we’ll be shooting each scene several times to get both a backup shot and a large amount of dialogue for us to work with. We’ll then reshoot each scene from various camera angles, as well as a large collection of cutaways, which we can use to really tighten the final dialogue in the final edit.
What we make up for by not having a script, we lose in time to shoot, but its worth it.
