Video Audio Replacer

Built for people who work in post-production

• Post-production editors replacing scratch audio with the final mix
• Sound editors delivering clean audio back to picture
• Assistant editors syncing a new audio deliverable to an existing video export
• Filmmakers swapping guide track audio for a polished final mix
• Film and TV composers syncing their score to a picture cut for director or client approval
• Broadcasters and online distributors updating audio on existing master

Why not just use your editing software?

Your NLE — Premiere Pro, DaVinci Resolve, Final Cut — can replace audio, but it re-encodes the entire video to do it. That means quality loss, long render times, and a bigger file than you started with. All for something as simple as swapping a track. Video Audio Replacer copies the video stream exactly as-is and only touches the audio. The result is identical video quality, a fraction of the time, and no unnecessary transcoding.
