Lessig argues that video, audio and other forms of media should be remixable in the same way that textual sources can be cut-up, such as citations in an essay. Should different media forms have different copyright restrictions; does taking a 10-second 'quote' from a feature film in a remix video equate with quoting 50 words form a published book in an essay or a published article in a journal?
If some remixes and mashups should be legal, even using copyrighted works, can we define what's 'remix' and what's just copying? Does remix involve fundamental changes in form, in length, in meaning or something else? If you had to offer a legal boundary between a legitimate remix, and an authorised copy, could you?
Should the intention of a remixed work matter? For example, in the US, 'fair use' means that political expression is largely protected, even using material under full copyright. So, for example, the 'prezvids' Tryon discusses are 'legal' as long as their intent (as political expression) is obvious. Australia, however, dosn't recognise the same right of political expression. Do you think intention matters (and if so, how do you 'prove' the intent of a piece of media)?
