The movie Lo Sfidante was created using only free software, in all phases, from editing to mounting the final video formats.
This choice, only apparently reckless, has once again demonstrated the maturity and solidity of these tools, that are as good as equivalent commercial tools with high cost per single license.
Therefore we are very pleased to introduce the list of software used to create this movie, and we thanks with glow and gratitude all their developers, for allowed me the free realization of a personal and intimate dream.

Thanks to Raffaella Traniello, for her small but highly significant technical hint in the use of Cinelerra.

Production would like to thanks also Giovambattista Fazioli, aka undolog.com, for hosting the downloadable files of the movie into his servers.
