It cannot be stressed enough that you need to plan carefully how you will shoot each installation and space. It helps if you do a pseudo edit already in camera. Think about transitions between shots while shooting as it will save unnecessary work later. Some experienced makers of video documentation have next to nothing to edit, when documenting a familiar type of installations, because the shots have been so well planned before shooting. Nevertheless you may prefer to shoot more material than needed to be archived for possible later research.
Remember always film a pre-roll before each shot, five to 15 seconds of extra material before each shot as well as a tail of similar length. This is crucial for editing and also to avoid some errors that might happen in the first frames of a shot.
