When you deposit a file on Patamu you can also choose a distribution license, which will indicate to the creative work users under which conditions they are allowed to diffuse and (possibly) modify the creative work.
In this page you can get a glimpse on how to choose the license distribution of your work.
One possibility is to to keep your work under "All rights reserved", meaning that nobody can use your work without your authorization.
You can also decide to share your video under a Creative Commons (CC) license, which allow the artist to selectively open some of the constraints of traditional copyright, allowing an easier diffusion of the artwork, but nevertheless imposing some conditions that protect the author. In the following paragraphs we describe the various types of licences.
CC Attribution - NonCommercial - No Derivs (CC BY-NC-ND)
This is one of the most used licenses, and the more strict among CC licenses: the author allows third parties to diffuse their artwork under the following conditions: his name must always be cited (attribution clause), the user cannot make many out of the use/distribution of the artwork (non-commercial clause), the artowork cannot be modified to produce derived artworks (no derivs clause).
CC Attribution - NonCommercial - ShareAlike (CC BY-NC-SA)
Also this license is often used, especially if somebady is willing to see his artwork manipulated by others (for instance through remixing practice): the author allows thirs parties to diffuse his artwork under the following conditions: his name must always be cited (attribution clause), the user cannot make many out of the use/distribution of the artwork (non-commercial clause). But with this license, the creative work can be modified and manipulated (of course, attribution and non-commercial clauses must be always respected). The derived artwork must necessarily be released under the same type of CC distribution licence (Share Alike clause).
If one of the clauses imposed by the author are not respected (for instance: somebody remixes an artwork and wants to earn money out of this remix, or doesn't want the remix to be released under the same license) then the original CC license released by the author is not anymore valid for him, and he must necessarily find an agreement with the author in order to find a new agreement outside the boundaries of the original CC license conditions.
Otherwise said: the authors imposes, through CC licences, some conditions that - if respected - allow third parties to diffuse the artwork without asking further authorizations to the author. But, if the third party exits the boundaries of the conditions allowed by the CC licence, then it is necessary to find a new agreement with the author, otherwise it will be forbidden to the third party to use and diffuse the creative work.
The other licences are more relaxed of the two that we explained above, because less conditions are requested:
CC Attribution (CC BY)
The original author only asks for authorship attribution.
CC Attribution-NonCommercial (CC BY-NC)
The original author only asks for authorship attribution and that his creative work is not used by third parties with commercial purposes.
CC Attribution-ShareAlike (CC BY-SA)
The original author only asks for authorship attribution and that the derivated artworks are released under the same license.
Finally, outside the CC licenses domain:
No Creative Commons license associated
Patamu also allows the user to choose not to associate a CC license to his/her artwork.
