Uncoupling script from screens

Currently scripts are coupled with images, i.e. voice and text are split between scenes. The lenght of a scene is actually cut to the length of narrative audio. 

So we cannot add blanks to show longer scene content before further speaking, or we cannot shift a script/audio to cover multiple scenes at once, we have to manually edit the scene, which is very time consuming.

That's why we should have the option to incouple audio from scenes. The visuals would be generated without any constraints from the audio, and the audi/captions could then be freely moved around the video, adding blanks
