To create this effect, drop two clips into your timeline, and overlap them by a few seconds. Drag the “displacement map” effect onto your top clip. Create a keyframe at the beginning of the overlap through the “vertical displacement” settings (we won’t be using horizontal displacement, so you can just set that to zero.) At the end of the overlap, create another keyframe and type in “5000” to the vertical displacement settings. Now, your footage will ghost trail into the next video. Add an opacity dissolve to the end to get rid of the hard cut-off. You may have seen double exposure treatment in photography, but the only example I can think of for video is the intro for True Detective. This opening sequence actually requires loads and loads of rotoscoping and blending, so I’m going to show you the easy way to create it in Premiere.

First, take a clip that has a subject against a stark white background. Drag it onto your timeline - along with a visually interesting video to layer underneath. All you have to do from here is go to Opacity > Blend Mode > Screen. This will blend the two clips and reveal the bottom clip beneath the top subject, but not the white background. This is an effect that I haven’t seen very often, but it turns boring footage into a trippy spectacular. To do this, take some video of an object with a solid color (sign, statue, dumpster, etc.).

Bring the footage into Premiere, and place it onto your timeline over another visually interesting clip.
