For various effects I have also been manipulating the video. For instance as it is going to be projected on to another surface, some of it coloured, I decided it would be better to have the film in black and white so as not to have any colour clashes. However some of the panels within the split screen are coloured, only on the top left and bottom right as those panels on the collage are more or less white. To change the colour in final cut you have to use the effects, which is on the bottom right.
Black and white is pretty easy, the colour correction part is also really useful as it means you can accentuate certain colours and get weird effects, like a very blue looking film.
I have also, to emphasise feelings of tension or rushing around, been changing the speeds, to make sped up or slow motion sections. To do this there is a little button which looks like a curly arrow.
Another effect is saturation, which I don’t totally understand, but which in combination with black and white makes a very grainy, atmospheric effect.
