Need to think about the composition how it would work in my project and to able to engaged the audience when watching a video / film etc.
Visuals need to be combined with subtitles, image, voice and signer... how it would work, where it all would be in position into the composition and if able to see everything happening in the video clip like they do on TV.
This is where multi modal comes in...
This applies to when you are reading book, magazine, newspaper..
Example comes in here is background material could be anything another frame would be signer on top of the background...
