Why Hollywood Uses 3 Computers to Mix TV & Film

In professional Hollywood TV and film mixing, we don’t build the soundtrack on one computer, we use multiple Pro Tools systems. In this behind-the-scenes video, I break down why mix stages often use 3 computers: ✅ Dialogue/MusicPro Tools system ✅ Sound Effects Pro Tools system ✅ Stem Recorder Pro Tools system This workflow keeps sessions stable, allows mixers to move faster, and helps us create a cinematic soundtrack without the system crashing or slowing us down. If you’re learning post-production sound and mixing from home, understanding this pro workflow will change the way you think and help you learn more how Hollywood mixers work.
