Have I to share my work (which consisted and based on CC 3.0 materials) with same license? I am ok to put links to CC 3.0 meaterials I've used, but have I to make my work also CC 3.0 for others?
Let's divide into 2 questions:
1) If I make a video, where only video is got from CC source, but audio is my property/product, and If I mix them, can I put copyright notice only for audio?
2) If I make 10 minute video, where only 2-3 minute part was CC video, cant I make whole video copyrighted (except those 2-3 minutes... placing that note in description)?
In CC 3.0, there is stated:
No additional restrictions — You may not apply legal terms or technological measures that legally restrict others from doing anything the license permits.
