Script Supervising is a skillset, not a software. Just as purchasing lavaliers & a mixer doesn’t instantly make one a professional Sound Mixer, neither does purchasing scripting software make one a professional Script Supervisor.
Producers, Directors, & Editors have shared “horror stories” of projects that suffered when an unqualified person claimed to be a script supervisor by virtue of downloading/learning scripting software, yet they lacked the actual skillset needed to execute the role.
Many professional script supervisors still use pencil-&-paper. Many professional script supervisors now use digital software. All professional script supervisors can execute the job’s essential skills without being a liability to production, whether digital or paper.
While software like “PeterSkarratt” & “ScriptE” help professional script supervisors condense their tasks, no software teaches nor represents the work of a professional script supervisor. Know your Script Supervisor’s experience-level & skillset (whether digital or pencil-&-paper), as not to cost production more in the end.
