LEAVE COLOUR 

In premier pro, we imported a clip and added in and out points to ensure it was not too long. 

 

We then searched 'leave colour' in the efects menu and dropped it over our clip whcih aplied the effect to our video. 

 

We then went under the effects control menu, and used the dropper icon to select the coloured folder 

 

The pink folder remained in colour while the rest of the clip was desaturated into back and white. 

 

The effect tracks the colour throght out the clip.
