No timeline. No menus. No render settings. You tell Claude Cowork what you want in plain English, it does the editing on the Livepeer network, and it hands back a finished video. This guide shows you exactly what to say — and what Cowork says back — so it's easy to follow.
Everything below is a real back-and-forth: the purple line is what you type; the blue line is what Cowork replies.
Cowork isn't a black box. It's a collaborator that keeps you in control — no surprises, no jargon:
The same Claude you already chat with — just make sure you're in a Cowork session.
Livepeer Agent shows up as a connected tool in Cowork. If it's already listed, you're ready. If not, whoever manages your Claude workspace turns it on once — then it's there for everyone.
Paste a link to your clip, or drag your file into the storyboard web app to get a link back. Then just start chatting — like the examples below.
The biggest time-saver. Most footage is filmed wide (16:9), but Reels and TikTok are tall (9:16) and the in-feed post is square (1:1). Instead of re-cropping by hand in three apps, ask Cowork once — it keeps the important part of the frame (faces stay in shot) while it crops.
Here's a wide video of our founder. Make it vertical for Reels and keep his face in frame. https://…founder.mp4
Got it — I'll crop this 16:9 clip to a 9:16 vertical and keep the speaker centered. That's about a cent. Go ahead?
Go
Done ✓ Here's your vertical cut: [link]
Want any of these next?
1 and 2
From this one video, give me three cuts: 9:16 for TikTok, 1:1 for the feed, and keep the original 16:9 for YouTube. Keep faces in frame. https://…clip.mp4
Three cuts coming up — about 3¢ total. Go?
Hand Cowork your clips (as links) in the order you want them and it assembles them into one video you can keep editing.
Stitch these three clips into one video in this order, and put a light upbeat music bed under it: 1) https://…intro.mp4 2) https://…product-demo.mp4 3) https://…closing.mp4
Stitched ✓ Here's your combined video with a soundtrack: [link]
It's fully editable — want to tweak anything?
3 — put a card that says New This Fall between clip 1 and 2
Point Cowork at a talking-head clip, testimonial, or voiceover. It listens, writes the captions, times them, and burns them on.
Add captions to this video from what the person is saying, and burn them in. https://…testimonial.mp4
Listening and writing the captions… this one has speech, so I'll time each line and burn them on.
Done ✓ Captioned video: [link] — and here's the transcript if you want to tweak wording.
This handheld clip is shaky and the audio has background hiss. Stabilize it and clean up the sound. https://…walking-shot.mp4
I'll steady the footage and strip the background noise — two quick passes, a couple of cents. Go?
Go. Also trim the silence off the start and end.
All three done ✓ Smoother picture, cleaner voice, and it now starts right on the first word: [link]
Long silent pauses (停顿音) and "um"s make a talk drag. Now you can strip both in one line — Cowork removes the dead air and the filler words, and re-stitches the speech so it moves. You can also point at a sentence you flubbed and have it cut.
This is a great take but it drags. Remove the long pauses and the filler words (the ums and uhs) so it's snappier. https://…founder-talk.mp4
Done ✓ Cut the dead air and the "um / uh" filler, kept every real word. Noticeably tighter: [link]
Want me to also cut a specific line?
Yes — cut the part where he says "scratch that, let me start over."
Removed that line and closed the gap seamlessly: [link]
One line adds your logo or a product shot to a corner, or a branded lower-third (a name-and-title bar that fades in). Great for watermarking, sponsor placements, or naming the person on screen.
Put our logo in the bottom-right of this clip. video: https://…clip.mp4 · logo: https://…logo.png
Logo added, bottom-right at 18% width: [link]
Want it bigger, more transparent, or in a different corner?
Add a lower-third that says Ada Lovelace, Founder & CEO. https://…interview.mp4
Added a branded lower-third that fades in — "Ada Lovelace · Founder & CEO": [link]
Cowork listens to (and watches) your video and turns it into a searchable list of moments — so you can jump straight to the part you need.
What's in this recording, and find where he talks about pricing? https://…webinar.mp4
Here's what I found — the pricing part is at 12:30–14:05: "So our starter plan is…". I also tagged the intro (0:00), the demo (4:10), and the Q&A (22:40). Want me to clip any of those?
Cowork finds the best moments, cuts them, reframes each to 9:16, and burns captions — a batch of shorts from one source, in one ask.
Turn this 45-minute podcast into 5 vertical clips for TikTok, captioned. https://…podcast.mp4
On it — I'll find the 5 strongest moments, cut each, reframe to 9:16, and burn captions. A couple of minutes.
Done ✓ 5 clips ready to post: [clip 1] [clip 2] [clip 3] [clip 4] [clip 5]
Cowork has 150+ AI models on tap — video, images, voices, music — right next to the editing tools. So a single ask can create new footage and finish it into your timeline. Two examples that are impossible in an edit-only tool:
Take one real founder/testimonial clip and ship a Spanish (or any-language) version that still sounds like them. No reshoot, no separate dubbing studio.
Make a Spanish version of this clip in the founder's own voice, with Spanish captions burned in. https://…founder-en.mp4
Here's the plan — I'll transcribe the English, translate it, clone his voice from the clip and speak the Spanish in it, swap the audio, and burn Spanish captions. About 15¢. Go?
Go
Done ✓ Spanish cut, his voice, captions on: [link]. Want French and German too?
You have a single product still and a 15-second customer clip. Cowork invents the lifestyle b-roll you never shot, then cuts it all into a branded reel.
From this product photo, put it in 3 lifestyle scenes (kitchen, gym, outdoors) and make each one move. Then stitch: the 3 scenes, then this customer testimonial, add upbeat music and our logo, and give me a 9:16 cut for Reels. photo: https://…bottle.png · testimonial: https://…review.mp4
Got it — I'll place the bottle into 3 generated scenes (keeping its exact shape & label), animate each, then assemble scenes → testimonial with a music bed, add the logo, and reframe to 9:16. ~60¢, about 2 minutes. Go?
Go
Done ✓ A 9:16 ad: 3 AI lifestyle shots of your bottle → the real testimonial → music + logo: [link]
Auto-clipping is table stakes now. The twist: Cowork also generates a branded intro card and glues it on — so every clip is on-brand, not just cut.
Cut this podcast into 5 vertical clips, and put a 2-second animated intro card with our logo and the episode title on the front of each. https://…podcast.mp4
Done ✓ 5 captioned 9:16 clips, each opening on a branded title card: [clip 1]…[clip 5]
He said the wrong price. No reshoot: find the line, regenerate it in his cloned voice, splice it back.
At one point he says "$49 a month" — it should be "$39". Find that line and fix it in his own voice. https://…founder.mp4
Found it at 0:48. I cloned his voice, regenerated "…thirty-nine dollars a month…", and spliced it in seamlessly: [link]
Localize and repurpose in one breath: three dubbed versions in the speaker's voice, each reframed and captioned for its platform.
From this clip, give me Spanish, French, and German versions in the founder's voice — each 9:16 with captions in that language. https://…clip-en.mp4
Done ✓ Three localized, voice-matched, vertical, captioned cuts: [ES] [FR] [DE]
A slow pan-and-zoom (the "Ken Burns" effect) makes a single image feel like real footage — perfect for b-roll, intros, or a beat between clips. It's fast and costs almost nothing.
Turn this product photo into a 5-second clip with a slow push-in, so I can use it as b-roll. https://…product-hero.jpg
Here's your 5-second push-in — ready to drop into a reel: [link]
Want a version that pans left instead, or a slow pull-out to reveal the whole scene?
Here's a start-to-finish session you can copy. Say each line to Cowork, glance at what it hands back, then say the next. You're the director; Cowork does the editing.
"Here's a 90-second phone video of our founder talking about the new launch: https://…founder.mp4"
"Stabilize it, clean up the audio, and remove the long pauses and the ums so it's snappier." → Cowork: about 3¢, go? → "Go"
"Now give me just the strongest 20 seconds as its own clip." (Tell it the moment, or the time range you liked. Flubbed a line? "Cut the part where he says …" and it closes the gap.)
"From that 20-second cut, make a 9:16 for Reels/TikTok, a 1:1 for the feed, and keep a 16:9 for YouTube. Keep his face in frame." → Cowork returns three links.
"Add burned-in captions to the vertical and square versions."
"Make a 4-second slow push-in from this product shot and put it at the end of each version: https://…product.jpg"
"Put our logo in the bottom-right of all three: https://…logo.png"
Say "just go, cap it at $20 a day." Cowork stops asking before small edits and only checks in before posting to social. Great for a heads-down editing session.
"Make this vertical, add captions, and put our logo in the corner." Cowork does them in sequence and hands back one finished cut.
Five testimonials? "Give all five the same treatment — clean, caption, and reframe to vertical." Cowork shows the total cost once, then does the set.
Don't love a cut? "Make the captions bigger," "start on the second sentence," "try a slower zoom." Cowork re-does just that part — the rest stays locked.
