CapCut export a silent video by mistake (2026)
Check the audio track before export.
Solo the voice track and preview once.
Confirm export includes audio, not video only.
Watch the mixer if music ducked the voice to zero.
Export ten seconds before the full timeline.
Save the export preset after it is audible.
Change one variable at a time and confirm what actually helped.
If a company policy is involved, rule that out before chasing client settings.
Write the working steps into a short checklist for next time.
Export or screenshot a good setup so reinstalls are faster.
If it still flakes, retest on a clean network such as phone hotspot.
