- supply a list of video paths and weights (can be a function of 't') -- prompt for instance segmentation? Mask?
- load each video and compute its flow field
- pool over all videos fields
- use this as an init...
wait no, that's not it. use each flow field as a separate channel, so we can attach different flows to different prompts, or some how apply them independently from each other.
anyway, some tool to facilitate/generalize working with multiple flow fields driving the same animation
