Where added audio helps
Use this page when the picture is ready but the spoken layer is missing, too quiet, or needs a clearer version for viewers.
Narration for explainers
Turn silent product demos, tutorials, lesson clips, and short updates into videos with spoken guidance.
Controlled script input
Write the exact words you want spoken so names, steps, disclaimers, and calls to action are easier to review.
Replace or mix audio
Use replacement for clean narration, or mix mode when the original video has room tone, music, or useful background sound.
How to add audio to a video
Keep the script short enough for the clip length, then review timing, volume, pronunciation, and rights before sharing the export.
Upload the source clip
Start with a video you own or have permission to edit. Short clips are easier to time and check accurately.
Write the voiceover
Match the script to the visible action. Add product names, safety notes, or attribution only when they are correct.
Choose voice and mix
Pick a voice preset, then decide whether generated narration should replace the original track or sit above it.
Review before publishing
Listen through the final render for clipped words, loud music, awkward timing, consent issues, and caption mismatch.
