I’m not familiar with this software stack, but some ideas which models might be useful:

segmentation models e.g. to blur content/remove it
super-resolution models
any kind of “filters” e.g. changing the appearance of the scene/person (e.g. different color of the clothing, hair etc.)
super-slowmotion
image/video stabilization
Generative models to create new scenes
denoising or general image enhancement (e.g. “night mode” enhancement)
