Make a great
video with
one prompt.

How to go from a raw phone recording to a finished Reel or TikTok, with captions, motion graphics, a podcast-quality voice and three thumbnails. What you need, the prompts to paste, and how to check the result.

01 · What you can make

Three real videos made with this kit

Same kit, same process, three different looks. Each one started as a plain selfie video. The agent wrote the plan, cut the pauses and retakes, built the motion graphics, processed the voice and designed the thumbnails.

Product review

80 s · teal brand stage, presenter card, logo that builds itself, price strike-through.

02 · What you need

Before you start

Five things. The first run on a new computer installs the tools (about 15 minutes); after that every video starts straight away.

1

Agent Cowork + this kit

The skills in project-template/.agents/skills (or the Video Montage plugin once it is released). The director skill video-director is the entry point for every video.

2

Magnific connected

For the 3 thumbnails (Nano Banana Pro, about 75 credits each) and any AI image or clip. Turn the connector on in Agent Cowork before you start the job.

3

Your recording

Vertical phone video, 1080 × 1920, 30 fps. One or more clips. Photos, logos and links are welcome too.

4

A computer that can render

Node 22+, Python 3.10+, ffmpeg with rubberband, 10 GB free. The agent installs Remotion, Whisper models and OpenCV 4.10 on the first run.

5

One clear goal

What should the viewer do at the end? "Comment PROMPT", "book a visit", "follow for part 2". The whole edit is built around it.

Optional

A brand file (colours, fonts, logo) in brands/. With it, the prompt can simply say "use the B Premier style" and every video stays on brand.

Per videoTypical
Time, unattended60 to 90 minutes for a 30 to 90 s Reel

03 · Record it right

A great edit starts with a good recording

The agent can remove pauses, retakes and "uhh", but it cannot fix a dark room or a missing sentence. Eight habits that make the biggest difference:

1

Light in front of you. A window or lamp facing you, never behind you.

2

Quiet room, phone close. Turn off fans and AC if you can. Record 2 seconds of silence first.

3

Phone at eye level, vertical, with space above your head for titles.

4

Stumbled? Pause one second and say the whole sentence again. The agent keeps the last complete take.

5

Name what you want to see. The director shows what you say: say "the price drops to 79 dollars" and the price will drop on screen.

6

Hook in the first sentence. Start with the most surprising line, not "Hi guys".

7

Say the call to action clearly, with the exact keyword: "comment PROMPT".

8

Wear a colour that contrasts with your background. A plain white top on a white wall makes everything harder.

"The zoom in", "the glass effect", "stop", "more like Codex": each frame shows the moment the words were said.

04 · Set up the folder

One folder per video

Copy project-template from the kit, rename it, drop your files in input, open it in Agent Cowork. That is the whole setup.

my-video-01/
├─ AGENTS.md        the agent reads this first
├─ CLAUDE.md        same file, other agents
├─ START-PROMPT.txt the prompt to paste
├─ AGENT-RULES.md
├─ VIDEO-QUALITY-CONTRACT.md
├─ style-log.json   looks already used
├─ input/           your clips, photos, logo
├─ brands/          optional style files
├─ deliveries/      the results land here
└─ .agents/skills/  video-director + 11
1

Copy project-template and give it a name, for example reel-2026-10-07.

2

Put your files in input/. Name clips in the order they play: 01-main.mov, 02-cta.mov.

3

Optional: copy brands/_template.json to brands/your-brand.json and fill in colours and fonts.

4

Open the folder in Agent Cowork in a new chat. Check that Magnific shows as connected.

5

Paste the prompt from the next page, note the start time, and let it run.

Keep style-log.json from your last video in the new folder. The agent reads it so the next video never repeats the same look.

05 · The prompt

Paste this, fill the brackets

This is the standard prompt for any video. It authorizes the full job, sets the quality bar and asks for a short report at the end.

Open this folder and follow AGENTS.md exactly.

Make ONE finished vertical Reel/TikTok from the files in input/
with the video-director skill. The full job is authorized:
work to the end without asking me.

- Goal: [what the viewer should do, e.g. comment PROMPT]
- Style: [brand file or colours, or "pick a new look"]
- Language: [English / Arabic], Western digits 0-9 only
- Voice: thick podcast voice
- Every visible thing I mention must HAPPEN on screen at that
  word. A label or a list does not count.
- Remove every pause, filler, false start and repeated phrase.
  Keep only one complete take of each sentence.
- 3 thumbnails with Nano Banana Pro on Magnific: tell me the
  credit cost, then continue without waiting.
- Do not deliver until qa_check.py prints PASS and the
  independent rubric is at least 40/50.

When done, reply with: total time, qa_check result, rubric
score, and the list of files in deliveries/.
Why "authorized"?
Without it the agent stops to ask small questions and the job takes hours.
Why "HAPPEN on screen"?
Without it the agent shows labels and lists instead of real effects. This one line doubled the quality in our tests.

06 · More prompts

Add one block for your situation

Paste the standard prompt, then add the block that fits. All of these are in PROMPTS.txt in the kit.

Two or more clips

Clips play in file-name order. If a
sentence is started in one clip and
said again in the next, keep only the
complete take.

Your own colours and fonts

Style for this video:
- Colours: bg #0A0A0A, main #FFD400,
  text #FFFFFF, warning #FF3B3B
- Fonts: Anton (titles), Inter 800
- Mood: bold, punchy, TikTok energy
Keep the readability and timing rules.

Arabic video

Language: Arabic. Captions right-to-
left, animate whole words, Arabic font
(Cairo or Tajawal) one weight heavier
than English. Western digits 0-9 only.
Transcribe with the language set to
Arabic and check timings twice.

Photos, no speaker (property, product)

Type: real-estate promo from the photos
in input/. Strongest view first, then
location map, room by room, specs from
input/specs.pdf only, price, contact.
No generated rooms. Music, no voice.

Long recording, short clip

Type: podcast-clip. Find the best 45 to
75 s moment with one clear idea and a
hook line in the first 3 s. Show who is
speaking. Deliver 3 options as clips.

Fix round after review

Review deliveries/final.mp4 and fix only
these, then re-run qa_check:
1. [at 0:04] the hook text is too small
2. [at 0:12] the glass panel covers my eyes
3. end card shorter (2 s)

07 · What happens after you press enter

The director works in 10 steps

The agent thinks like a director before it writes any code. Everything goes into one plan file, work/video-plan.json, and every step has a check before the next one starts.

1
Director

Understand. Reads every file, transcribes the speech twice, writes a 6-line brief with one goal.

2
Director

Classify. Talking head, podcast, promo, real estate, explainer, AI story… each type has its own rules.

3
Director

Concept and look. One idea that makes this video special, plus colours, fonts and captions.

4
Director

Beat plan. Second by second: what happens on screen. Every named thing becomes a cue.

5
Sourcer

Assets. Your files, your brand, official logos and screenshots, licensed icons and fonts, real sources.

6
Generator

Generate. Only what is missing, through Magnific, with the credit cost shown first.

7
Compositor

Compose. Builds the video in Remotion: captions, motion graphics, layouts, transitions.

8
Sound

Sound. Thick podcast voice, one sound effect per visual event, loudness at −14 LUFS.

9
Critic

Quality check. Automatic checks plus a separate model that looks at the frames and scores them.

10
Delivery

Deliver. Final video, 3 thumbnails, the plan, short notes with scores and credits.

Agent Cowork · Video kit9
09 · Thumbnails

Three covers, every time

The agent sends a sharp frame of your face to Nano Banana Pro as a reference, generates three different scenes with empty space at the top, then adds the title in code. You pick the one you like.

Real covers from the effects showcase (first three) and the security warning video.

Title in code

Generated images misspell words. Titles are drawn afterwards, 2 to 5 words, large and bold.

Safe zone

Instagram's grid shows only the middle 3:4. Titles stay inside it, nothing important at the bottom.

Cost first

About 75 credits per image. The agent states the total before generating.

Agent Cowork · Video kit10
10 · Choose a look

A new look for every video, or your brand every time

By default the agent picks a style recipe it has not used in your last three videos. If you give colours, fonts or a brand file, those win.

  "tone": "confident, short"
}
Save one file per brand. Then the prompt only needs one line:

Style: use brands/my-brand.json

Readability rules still apply: if a colour is hard to read on your shirt, the agent adds a dark outline.

11 · Before you post

A 2-minute review

Watch it once on your phone, sound off

  • Something happens in the first second
  • Every caption is readable and matches what you said
  • Each thing you named actually appears on screen
  • Your face is never covered by text or panels
  • No "uhh", no repeated sentence, no awkward pause
  • The call to action is clear, and the end card is short
  • Thumbnails: pick one, title spelled right

If something is wrong

Use the fix round prompt (page 7) with the time and the problem. Small fixes take 10 to 15 minutes, mostly the new render.

Common problems

You seeDo this
"Magnific is not connected"Turn the connector on, start a new chat in the same folder, run again.
qa_check says FAIL, runtime below 0 %The check was given one clip only. All clips must be joined for --original.
Labels instead of real effectsMake sure the prompt has the "HAPPEN on screen" line and that cues.csv exists.
Stripes or glitches in the render (Windows)Ask the agent to switch from OffthreadVideo to Video and re-render.
The job runs over 2 hoursOpen RUN-LOG.md to see the slow step; usually first-time installs or a render retry.
Every video looks the sameKeep style-log.json between videos, or give a style block.
