In my last edit I already adjusted each clip. I used the Brightness & Contrast filter (to increase the contrast), as well as the colour balance filter (to remove any colour cast on each clip). After getting feedback from the class it was agreed that the clips still looked too dull and needed to appear more dynamic. The shadows weren't dark enough, the highlights weren't light enough and the midtones were bland.
To improve this I was told to use an effect/filter called '3-Way Colour Correction'. Using this I could increase overall saturation, and manually increase or decrease the shadows, highlights and midtones to create something that looks more dynamic. The increased saturation really makes the colours come out more and the increase in contrast is very noticeable. Some of the shots that had very dull lighting now look a lot more bright and appealing on the screen.
To show the difference I have put together a video showing both the original clips with no adjustments, and the new edited version. The left side of the screen is the new adjustments and the right side is the original clips. Watching it in this way really shows the difference these filters made to making the scenes look more interesting and vibrant. I halved the speed of the video so it is 30 seconds long, and allows you to see the changes better.
