Thanks to an acquaintance with a friend who is a multi-media artist, I started working with video a few years ago. namely, since he organizes a festival where several artists participate, I helped him by recording the performances that the artists performed live, then I shortened those videos to about 3 minutes, added a title frame at the beginning and end of each video, and finally we those video files were put into a multimedia pdf catalog that we made every year and sent to the participating artists.
