To begin with, I put all the clips into Adobe's Premiere Pro (A video editing software) and arranged them into order. I trimmed most of them so they weren't too long for the viewer. In particular, I had two videos that transitioned well due to the camera cutting away which caused motion blur. This can be seen at 00:20 seconds into the video.
I then added some vintage overlay effects throughout the video. This helped transition the shots smoothly while still maintaining the vintage feel. I found this overlay on youtube and downloaded it and placed it onto my sequence. In order to get rid of the black (so the video could be seen), I had to change the blend mode to 'screen'. This was done for all the overlays in this video.
I then finally added a noise overlay just to finish off the base video. This added a little grain to the sequence which helped support the vintage feel.
Next, I copied the sequence into a new sequence and added a film overlay/frame. This added the final touch of making it as authentic as possible.
I also colour-corrected the sequence. For this, I had to use a plugin called 'Lumetri Colour'. This is, essentially, a mini Adobe Lightroom inside Premiere Pro. I increased the saturation (around 48%) and reduced the temperature of the video (-34 C). This added a slight blue tint to the footage. I also increased the contrast slightly so some of the colours would pop out more.
