I’ve used After Effects since 1992 (when it was published by CoSA, prior to its acquisition by Adobe), so for a short-duration piece like this, I use it for all editing, color grading, titling, and effects.
I had to clean up a few shots were either dirt had fallen or Blue Tack was visible while anchoring a puppet to a surface. The only shot that uses any camera movement – really just an experiment with that awful tripod head – had to be horizontally stabilized. The rest of the post-production effects were limited to color grading. After I did the sound design, the rhythm of the syringe’s movement in scene one required a slight re-edit, but the picture was otherwise locked before sound was added. I layered in some post-production effects, but they all detracted from the rich textures that came right out of the camera, so they were all stripped out.
The piece was mastered in UHD/4k with 24 bit, 96kHz sound, but the version available online is 1080p with 24 bit, 48kHz sound.
