Before the final dubbing sessions on feature films, several days to several weeks will be allotted for the predubbing of dialogue and effects. During the predubbing, the dubbing mixers premix as many as 30 or 40 tracks down to perhaps 18 or so to make the final mix manageable.

If your show includes a lot of effects, for example, explosions, music, sound effects, or loud noises over romantic dialogue, then your sound-effects supervisor will probably recommend a predub or prelay.

Once the materials arrived at the stage, a dozen recordists and mix technicians required a half an hour to load the three or four dozen tracks a predub might require.
