Jelaskan Pascaproduksi dari Raiders of the Lost Ark

Pascaproduksi berlangsung sekitar dua bulan dan berfokus terutama pada efek khusus dan pengambilan gambar berskala kecil. Versi awal film berdurasi hampir tiga jam sebelum Steven dan Kahn mennyunting ulang menjadi hanya kurang dari dua jam. Lucas was happy with this edit, but later asked if he could shorten the ending. He and Kahn collaborated on the edit; Spielberg said he was happy with their changes. The final cut of the film runs for 115minutes. Marcia Lucas opined there was no emotional closure for Jones and Marion because she was absent following the closure of the Ark. Marcia is not credited in the film, but her suggestion led Spielberg to shoot a final exterior sequence on the steps of San Francisco City Hall showing Jones and Marion together.

Other changes included the addition of a scene where the Ark makes a humming noise in the Bantu Wind hold and the removal of a scene showing Jones holding on to the U-boat periscope to follow the Nazis; Spielberg thought it looked poor and hoped the audiences would not care how Jones accomplished the feat. Lucas removed a scene of a man fainting at the sight of Indiana and Marion emerging from the Well of Souls because he thought the joke did not fit with the tone of the movie. Shots of the Douglas DC-3 in which Jones flies to Nepal were repurposed from the adventure film Lost Horizon (1973), and a street scene outside Jones's home was taken from The Hindenburg (1975). Spielberg said it was cost-effective and only sharp-eyed viewers would ever notice. Special effects supervisor Richard Edlund maintained the street scene was done with miniatures.
