FAQs
Does video denoising affect video quality?
Only the audio is processed. The video track remains untouched. Output as MP4.
What strength should I use?
50-70% for typical indoor noise, 30-50% for light hum, 70-90% for strong wind. Preview first — it takes seconds to find the sweet spot.
How fast is it?
Audio is extracted, denoised, then re-muxed with the original video. Time depends on video length, not resolution — 4K takes about as long as 720p.
Types of Video Noise AI Can Remove
- Electrical hum: steady buzz from recording gear or capture cards (50/60Hz and harmonics)
- Fan/AC noise: constant background tone from indoor recording
- Wind rumble: classic outdoor low-frequency noise (medium strength works best)
- Hiss: white noise from old gear and low-fidelity microphones
- Heavy steady room tone also improves noticeably
How It Works: Audio-Only Processing
Three steps: extract the audio track from the video → DeepFilterNet AI analyzes and suppresses noise frame by frame (preserving voice frequencies) → the denoised audio is re-muxed with the original video.
The key is step three: video data is never touched — every frame stays byte-identical, so output quality matches the source exactly. Processing time depends on audio length, not resolution: a 4K video takes about as long as 720p.
Strength Settings That Work
Always preview before processing the full video — previews are instant and find the right strength in seconds.
| Noise Level | Strength | Notes |
|---|---|---|
| Light equipment hum | 30-50% | Gentle suppression, voices 100% preserved |
| Typical indoor noise | 50-70% | The sweet spot for most scenes |
| Heavy wind/ambient noise | 70-90% | Big noise reduction; slight artifacts possible on voices |
