AI Video Editing Workflow: Descript + Underlord (60/40 System)

How we use AI to edit video content without a production team

We record directly in Descript, let it generate the transcript, then run a repeatable Underlord prompt + review pass to get a clean cut fast. Without making the video feel over-edited.

Tools

• Descript: Record, transcribe, and edit by deleting words in a document-style transcript instead of cutting on a complex timeline.
• Underlord (Descript's AI layer): Helps apply repeatable editing decisions (cleanup, pacing, structure, captions, layouts) using guided prompts and your rules.

The promise: AI gets you to a strong first cut (~60%). You do the last ~40% by reviewing, fixing, and polishing.

How we use AI to edit videos without a production team

Video content is one of the highest-ROI activities a founder can invest in. If you aren't producing enough of it, editing time could be the reason.

Retakes, filler words, dead air, pacing cleanup — that's where the hours go, or where the editing bill racks up.

Cut that time and you can publish more, build authority faster, and get more content working for you over time.

Descript, paired with its AI layer Underlord, tackles that grunt work directly.

As a video editor and social media manager at AI Operator, I've edited a lot of content across different tools. The real time sink is always the same: cleanup, pacing fixes, and repetitive cuts.

Descript (especially with Underlord) helped me offload that busywork, so I can focus on the final 40% that actually moves the video forward: structure, flow, and the creative polish that makes it feel human.

Here's the exact workflow we use at AI Operator to go from raw recording to publish-ready, without a production team.

Descript with Underlord can handle 60% of your editing

If you're new to editing, here's the simple mental model:

Descript is a video editor where you edit by working with the transcript. You can delete a sentence from the text, and the video cut happens automatically.

Underlord is Descript's built-in AI co-editor. It helps you apply repeatable editing rules (pacing, cleanup, structure, captions, layouts) in a guided way. Think "AI assistant for editing decisions," not "magic one-click publishing."

This combo is ideal for founders because it removes the slowest parts of editing. It also makes the workflow consistent so your output doesn't depend on your energy that day.

Our workflow: from raw recording to publish-ready cut

Step 1: Start with the right AI tools

Our founder Tim records tutorial videos directly in Descript so the workflow stays smooth. Recording, files, transcript, cuts, comments, and feedback live in one place.

That matters because it reduces two common sources of friction:

• exporting and importing files across tools
• version mixups during reviews

Note: If you don't record everything in Descript, that's fine. The workflow below still works if you import video into Descript after recording elsewhere. The key is that once it's inside Descript, you're editing from the transcript.

Step 2: Double-check the transcript (don't miss this step)

This is the "secret step" people skip.

Underlord and many transcript-driven edits are only as good as the transcript. If the transcript is out of sync, missing sections, or has major errors, the AI can cut the wrong moments or tighten pacing in the wrong places.

Checklist:

• Listen once (even at 1.5x) to make sure the transcript matches the audio.
• If multiple clips were recorded, confirm they're in the correct order.
• Fix obvious errors in names, product terms, and key phrases.

Step 3: Create Branded Content with Templates

To ensure your videos look professional and stay consistent with your brand colors and fonts, you need a Layout Pack. The goal is to create it once and use it in every video, removing the need for manual design work.

Why this saves time

Instead of manually resizing every scene, a Layout Pack lets Underlord automate your entire brand style in one click. It ensures every video looks like it was made by the same professional team, even if you're editing solo.

How to create one

1. Start with Gallery Templates: Descript comes with dozens of pre-made layout packs. Pick one that matches your vibe (e.g., "Corporate," "Minimal," or "Social").
2. Customize for your Brand: Open the layout and swap the default fonts and colors for your own.
3. Save & Name it: Save it to your Drive with a clear name (e.g., "AIO Brand Pack"). You will use this exact name in the Underlord prompt in the next step.

Step 4: Let AI do the 60%

Descript is dramatically faster because you don't have to hunt through a timeline. You edit the transcript like a document, and the video updates automatically.

Descript already has AI tools like Remove retakes, Remove filler words, and Studio Sound. You can run them one-by-one manually.

Underlord is the shortcut: one well-written prompt can combine those steps into a single guided workflow, using your rules (pacing, what to cut, what must stay, your brand style).

Best practice: have Underlord draft the plan first, then get your approval, then apply the changes.

Think of Underlord as the editor's brain, and Descript as the editor's hands.

Underlord monster prompt (copy/paste template)

Use this when you want Underlord to run the edit using your brand's layout pack and your style rules:

Edit this video using my (Layout pack name) layout pack.

Primary goal:
- Tight, energetic pacing without sounding over-edited or robotic.

Cleanup (do this first):
- Remove retakes (prefer the best complete take; usually the last clean take).
- Remove filler words lightly (keep a natural rhythm; don't purge everything).
- Tighten long pauses and dead air, but do not cut mid-sentence or mid-thought.

Audio:
- Apply Studio Sound to 80%.
- Add relevant sound effects to make it more engaging.

Structure + layouts:
- Break the video into clear scenes. Avoid unnecessary layout changes.
- Use camera/speaker layouts for talking-head sections.
- Use big-fact or quote layouts for key moments.
- Add chapter markers for major topic shifts.

Output:
- Apply edits across the full timeline.
- Preserve the speaker's intent and phrasing; don't regenerate the script.

Before making any changes, summarize the edit plan and ask me to approve it.

Secret Tip: Do one gold standard edit manually first. Exactly the way you like your videos to feel. Then ask Underlord to reverse-engineer your editing style into a reusable prompt. Use that prompt as your default starting point for every future project.

Step 5: Let a human do the 40%

This is the final pass that keeps the video feeling real.

Quick review checklist

• Listen straight through at 1.0x and take notes.
• Undo anything that feels machine-tight.
• Fix weird jump cuts and transitions.
• Add B-rolls and motion graphics to give it a premium feel.

Remember, Underlord isn't as good as a person at noticing everything on your screen. So if you recorded a screen share, you must manually blur/hide anything private (like API keys, passwords, emails, or customer info) and double-check it before you export.

Use Descript for what it's best at:

• structural cutting
• pacing cleanup
• transcript-driven editing
• captions and repurposing

The real benefit: editing becomes a system

The biggest win isn't editing faster. It's making editing repeatable:

• same workflow every time
• predictable output quality
• fewer where-did-that-cut-happen moments
• easier handoffs between team members

Descript turns editing into an operator process: clear steps, fewer moving parts, and faster iteration. That's how you publish consistently without editing becoming a bottleneck.

This is the exact workflow we run at AI Operator. If you want to build something like it for your own content, book a call — we'll walk through what that looks like for your business.
