Super 8 only has a frame rate of 18fps, so there's a visible judder to the movement. In order to smooth the motion I attempted to apply some frame interpolation using RIFE ( https://colab.research.google.com/github/HeylonNHP/RIFE-Colab/blob/main/RIFE_Colab.ipynb ) . The frame rate here was doubled to 36fps.
Whilst the camera movement looked smoother it also looked less natural. The process also introduced some strange looking visual artifacts. Maybe this would have worked better with cleaner input frames. There are also a number of settings to adjust in RIFE.
