Roll slitting and rewinding is an essential part of the finishing process. The rolls of aluminium foil are then slit on slitter rewinding machines into smaller rolls. Film loading, winding, rewinding, and focus adjustments are accomplished manually. The EOS 100 came with a motorised belt drive for film winding and rewinding.

He defeats Betamax by rewinding him using his newly acquired door. Her whole teleporting/rewinding mechanics [are] so unique and fast-paced.

This can be accessed by "rewinding" the first track on some CD players.
