For now one can only edit Images using Prisma. Though Prisma is going to add Video editing feature very soon. Prisma co-founder Alexei Moiseenkova has promised to introduce a new tool inside the app "in the next several weeks" to allow you to edit video clips in the same artistic style.
The Application lets you edit your Images by adding some cool effects including Picasso, Monet, Van Gogh, Munch, Levitan and Kandinsky.
