Audio quality is one of the most important factors in whether people keep watching. Background noise, wind, echo, and accidental profanity all make viewers tap away fast. Captions has two tools that fix this automatically.

​
Denoise: remove background noise and echo

Denoise separates your vocal track from the background and removes:
  • Environmental noise (traffic, HVAC, crowd noise)
  • Echo and reverb from recording in a room
  • Wind noise
  • Keyboard, mouse clicks, and other ambient sounds
The result sounds like you recorded in a proper studio, even if you recorded in a coffee shop.

​
When to use Denoise

Use it whenever:
  • You recorded somewhere you couldn’t fully control the sound
  • Your audio has a slight hum or room echo
  • You used a phone mic instead of an external microphone
  • You want to clean up the audio before adding captions (better audio = better transcription)

​
How to apply Denoise

1

Open your project

Import your video and open it in the editor.
2

Apply Denoise

Tap Denoise in the editor toolbar. It applies instantly with no settings to configure and no sliders to adjust. Captions automatically determines the right amount of noise reduction.
3

Listen and verify

Scrub through your video and check that the vocal track sounds clean. The background should be noticeably quieter while your voice sounds natural and full.
4

Disable if needed

If Denoise over-processes the audio and makes it sound thin or artificial, tap Denoise again to toggle it off.
Apply Denoise before generating captions. Cleaner audio produces more accurate transcription.

​
Censor: automatically bleep unwanted words

Censor detects and bleeps curse words automatically. Useful for:
  • Making content available for all audiences
  • Editing out accidental slips in otherwise usable takes
  • Creating a clean version of raw footage for brand-safe platforms

​
How to apply Censor

1

Open your project

Import the video and open it in the editor.
2

Tap Censor

Tap Censor in the bottom navigation. Captions automatically detects and bleeps curse words throughout the video.
3

Censor individual words manually

To censor a specific word that wasn’t caught automatically:
  1. Tap the word in the captions to edit it
  2. Add ** anywhere in the word (e.g. sh**t)
  3. Make sure Censor is enabled. If it doesn’t apply, toggle it off and back on
Some caption styles have Censor enabled by default. If words are being censored unexpectedly, tap Censor to disable it.

​
Using Denoise and Censor together

These tools work independently and can be applied at the same time. A common workflow for polishing raw footage:
  1. Import your video
  2. Apply Denoise to clean the audio
  3. Apply Censor to catch any language you want removed
  4. Generate captions (on cleaner audio)
  5. Style and export
