Open Audio with Remove all audio already selected and export a silent video copy locally.
Muting removes the audio track from the delivered video; extraction creates a separate audio result. WAV is suitable for editing and transcription but is much larger than compressed audio. Listen for the complete beginning and ending, not just for the presence of a file.
Quality control before publishing
Open the exported file outside the editor. Confirm duration, orientation, framing, audio synchronization and container. Check the first frame, every edit boundary and the final frame; a technically successful export can still contain a clipped subject, silent section or unwanted padding.
1
Compare output duration with the intended active timeline.
2
Check the result at normal size and full-screen.
3
Keep the untouched source until the destination accepts the export.
Repeatable preset for agents
Agents can use the official recipe `mute_video` through window.QuokkaPixVideoAgent or the Video MCP tools. The recipe prepares settings only: the source file is still selected locally in the browser, the exact payment tier is measured after selection, and the result manifest remains the source of truth for completion and QA.
