Video Editing: Overlaying

 I used this technique in order to add two videos on top of each other. the first step is to choose the section of video you want to overlay. After this, you place one of the videos in the 'video 2' section  above 'video 1'. Then i clicked on the 'effect controls', after this you click on opacity and choose a blending mode, similar to photoshop. I looked through the list in order to find the best suited setting which was 'colour dodge'.

 For this shot i did the exact same as above, but this time i chose 'Darker Colour' as the blending mode.
