1 Import file
Go to imovie’s projects pane. Click ‘Create New’. Choose Movie. Choose File>new Event. Label it. Click ‘Import Media’. Browse to our ‘winter_start.mp4’ file. Click ‘Import Selected’.
2 Add to timeline
Drag the imported winter clip into the timeline. Tap the spacebar to play. The colours are cold and the tones are flat and lack the contrast produced by a stronger sun.
3 Balance the colours
Click on the ‘Colour balance’ icon above the viewer. Click the ‘Skin Tone Balance’ button. Click the eye dropper on the girl to warm up her skin tone. Click the tick.
4 Warm it up
Click the ‘Colour correction’ icon above the viewer. Drag the Adjust saturation slider to the right for more vibrant colours. Drag the temperature slider right to warm up the clip.
5 Increase contrast
The tones in the original clips are rather flat due to the overcast sky. To create a brighter and more summery look, drag the white Increase contrast slider to the right.
6 Create layered clips
Click on the clip in the timeline. Choose Edit>copy. Place the playhead at the end of the clip. Choose Edit>paste. Drag the duplicate clip on top of the original as a new layer.

8 Reduce filter intensity
Our filtered layer’s highlights are blown out. Click ‘Video Overlay’ above the viewer. Choose the ‘Cutaway’ overlay style. Reduce Opacity to recover some highlight detail.
9 Slow it down
To enhance the look of a sunny day click on the top clip and click the ‘Speed’ icon. Set Speed to Slow and choose 50%. Repeat this step to slow down the clip on the bottom layer.
