To cut down the footage, i used the 'In' and 'out' method of getting the right moments of the chip.
To get the effect of the evidence over the footage, i put the footage over eachother, and double clicked on the evidence clipping. I then selected sped up the footage to roughly 2500%, and selected the opacity to be 100. This made the footage translucent, so you can see parts of the evidence over the river time lapse.
