Video Editing · Lesson 3 of 6
Cutting and Trimming with AI
Stop scrubbing timelines. Edit your video the way you edit a document.
After This Lesson, You Will Be Able To
Cut a raw talking-head video down to its best version using transcript-based editing — removing filler words, long pauses, and bad takes.
The Old Way vs The AI Way
AI way: Descript transcribes your video in 2 minutes. You see the whole video as a text document. Delete the words 'um', 'uh', or any sentence you don't want. The video updates automatically. 20 minutes of footage becomes a tight 5-minute video in under 30 minutes.
Cutting Techniques with AI
Transcript-based editing (Descript)
Upload your video → wait for transcription → edit the text. Descript automatically removes the corresponding video when you delete text. You can also use 'Remove Filler Words' to auto-delete all instances of 'um', 'uh', 'like', 'you know' with one click.
AI silence removal
Both CapCut and Descript can automatically detect and remove long pauses in your video. This alone can cut 20–30% of a raw recording's length without any manual editing. Essential for talking-head and tutorial content.
Multicam / B-roll cuts (CapCut)
For more advanced edits: use CapCut's auto-cut feature to sync cuts to music beats, or import B-roll clips and let CapCut suggest where to insert them over your talking-head footage.
Pacing check
After cutting, watch your video at 1.5x speed. If it still feels slow at 1.5x, cut more. A well-edited video should feel slightly rushed at 1x speed — that's how you know you've cut enough.

Prompt to use
I'm editing a [length]-minute talking-head video. Here's the transcript: [paste transcript]. Help me: 1) Identify the sections I should cut (dead air, repetition, off-topic tangents), 2) Find the strongest 'hooks' in this footage that should be at the very start, 3) Suggest where to add B-roll to break up the talking head, 4) Identify 3 short clips (under 60 seconds each) I could extract as standalone TikTok or Reel clips. Be specific about timestamps or transcript sections.
The raw footage is not the content. The edit is the content. How different would your videos feel if you cut 30% more than you currently do?
Key Takeaways
Transcript-based editing in Descript makes cutting video as fast as editing a document.
Auto-remove filler words and silence in one click. You don't need to manually find every 'um'.
A well-edited video should feel slightly rushed at 1x speed. That's the target pacing.
After cutting, always look for 60-second clips you can repurpose — never waste good footage.
Edit a raw video down to its tightest version.
Take your most recent raw recording. Import it into Descript or CapCut. Remove all filler words, all pauses over 1 second, and any section that doesn't add value. Watch the final cut at 1.5x speed. If it still feels slow, cut more. Compare the raw and edited lengths — aim to cut at least 25%.
