Re-recording (video gaming)
（重定向自Rerecord）
Re-recording is the act of using a save state while recording a tool-assisted speedrun. By loading a saved version of a prior machine state during the emulation, the movie that is being recorded will be trimmed to the point in time at which this prior state was current, allowing one to continue recording the movie from that point. One of such occurrences is called a re-record or undo. It is used mainly to correct errors in the making of tool-assisted speedruns, and can only be done with an emulator that supports the use of save states while recording the player's input.
