Speed Up Zoom Recordings by Removing Dead Air

Zoom lectures, Microsoft Teams meetings, and online course recordings are full of dead air: the host waiting for people to join, screen sharing delays, the professor reading chat questions silently, or long pauses between topics.

5cut detects these silent segments and removes them automatically.

Common dead air in online recordings

• Waiting room periods — "Let's give people a few more minutes"
• Screen sharing transitions — gaps between apps
• Chat reading — professor silently reading questions
• Breakout room transitions
• Technical difficulties — "Can everyone hear me?"

How it works

1. Download your Zoom recording to your iPhone
2. Import into 5cut from Photos or Files
3. Choose a Smart Mode — Gentle, Moderate, or Aggressive
4. Export — trimmed recording saved to camera roll

Works with all platforms

5cut works with Zoom (MP4, M4V), Microsoft Teams, Google Meet, Webex, Blackboard Collaborate, Canvas Studio, Panopto, Kaltura, and any MP4, MOV, or HEVC video.

Better than 2× speed

2× makes both speech and silence faster. If the professor speaks in a language you're learning, that's impossible to follow. Silence removal keeps speech natural and only cuts the parts where nothing is said.

Add subtitles too

After removing silence, generate subtitles in 30+ languages and burn them into the video. Great for foreign language lectures or poor audio quality.

Batch process a whole course

Queue up a full semester of recorded Zoom lectures with Premium batch processing. Processing continues in the background.
