> How educators use CleanCut to create concise, engaging educational content.

## The educational content challenge

Recording lectures is essential for online learning, but raw recordings are often bloated with dead air: long pauses while thinking or checking notes, technical setup time and interruptions, and students losing focus during silent moments. For instructors recording 5-10 lectures per week, editing becomes a bottleneck.

## The CleanCut solution

CleanCut automatically removes dead air from lecture recordings, creating tighter, more focused educational content:

- **Faster production** — edit lectures in minutes, not hours.
- **Better engagement** — students stay focused with tighter pacing.
- **Shorter videos** — reduce 60-minute lectures to 45-50 minutes.

## Typical workflow

1. Record your lecture — teach naturally, don't worry about perfect delivery.
2. Import the recording into CleanCut.
3. Auto-detect silences: threshold -35dB, minimum duration 1.0s for natural pacing.
4. Batch process multiple lectures at once (Pro).
5. Export and upload to your LMS.

## Real results

- **20-30%** average reduction in lecture length.
- **95%** time saved on editing.
