If the videos are completely to your liking, we ask to agree to a 'picture lock'. This means that the video montage is now 'locked'; adjustments aren't longer possible (free of cost).
We mark this moment so explicitly because building a video template based on a video montage is a very labor-intensive process. Any change in the video montage would basically mean we have to start all over again. That's why this moment in the process is so important and we need a formal agreement to proceed. So any colleagues / managers / CEO's / office dogs / etc. that might have an opinion, need to be consulted before picture lock.
