Two problems:

- It'll bleed on fast motion. Hair in the wind would just not work.

- Incandescent lights are out.

You could solve both by having two ghost frames shot very close to the real frame (no need to evenly space the frames, after-all) and using strobing a high powered laser.

You'd need very fast sensor or another one optically on the same position.

At some point higher fps solves it. Is 240 fps enough?
