Do I need a written contract when the job is a still and a clip?

Yes, the paper has to say which dishes get a still, which a clip, and whether the edit is in. Without that, a morning of stills is paid for and the clip is not there. List the dishes in two columns: still and clip. In the sierra the paper talks about stills and on the day of the pass nobody edits the clip. The paper names each dish as still, clip or both, and says whether the edit is included.
