This was a commission for the comedy duo Chris & Jack for one of their weekly YouTube sketches.
For this project I used Adobe After Effects for VFX. I applied a camera shake in select parts to mimic an earthquake. I also used stock footage of debris and smoke throughout the video to add to the atmosphere and for effect, like the dust on the floor when jack rolls into the room.
The door was originally a green screen matte, I used a combination of textures and clip art to create an aztech-style door which I color graded it to match the rest of the room. I also added in the rock that falls on jack at the end, for that I used an image of a rock and combined textures and blending modes in After Effects to match the grittiness of the cave.
As Jack was still in that shot I duplicated the scene and used a mask on top of a shape layer and used Motion Blur on the rock so it would make Jack 'disappear' under the rock.
