It all depends on what your aims are or how complex your AV shows are, i.e. on the type of media you want to edit and output. Under Versions and Licenses you will find a table providing information on the functions of the various versions. If you are not sure which to choose or if you have questions, turn to one of our dealers who would gladly give you advice. A list of all dealers can be found in our website. If you can't find a dealer near you feel free to contact us directly. See AV Stumpfl contacts.
