DaVinci Resolve — cut a long screen recording into a tight demo

Overview

The fastest way to turn a 60-minute screen recording into an 8-minute watchable demo. Uses Resolve's AI Transcription plus Remove Silent Portions to do 80% of the work automatically, then refines manually. The core principle: do not waste your time scrubbing a waveform when Resolve can find the dead air for you.

When to use

Symptoms:

• You recorded a 30-90 minute demo, talk, or tutorial and need to ship a tight version
• You said "um" too many times
• There are long pauses between sentences where you were thinking
• You did 2-3 takes of the same explanation and need to pick the best one
• Phrases like "raw recording is too long", "remove silences", "fix the ums"

When NOT to use:

• Multi-camera interview / talk-show — that needs the Multicam workflow (Editor's Guide ch. 4).
• Tight musical edits to a beat (rhythmic cuts) — use the Cut page manually.
• The recording is already under 10 minutes — manual editing is faster than this skill.
