You can attend the certificate courses in video production on a part-time basis. For a quick completion, choose a 2- or 3-day course on weekdays (approx. 14-18 lessons in small groups). The costs for this are between 600 and 1,200 francs.
Longer courses last 1.5-4.5 months (approx. 24-90 lessons) and take place on Tuesdays or Saturdays. You can expect to pay around CHF 590-3,200. In some cases, project presentations including documentation of the individual work steps are required at the end of the course.
