Team Radio Earpiece AI ad with Liu Xialan
A race engineer cuts through pit-garage noise with one tap on her earpiece. Four shots, one product still and a pack of 19 character images. Below is every step we took, in order: which pack files we uploaded, the exact messages we sent to the AI, the settings, what came back, which takes we threw away, and how we cut the ad. Download the pack and you can make the same ad.

What you need
- 1
Liu Xialan's character pack
Free download, no account needed. Unzip it; the folders are numbered (01_character_reference, 02_turnaround_views …).
- 2
An image model that takes several reference images
We used GPT image model, image-to-image through the KIE API. Any image model that accepts 2–4 reference images plus a text message works the same way.
- 3
Kling 3.0 image-to-video
We used Kling 3.0 image-to-video (720p, no sound) with a character element (a saved set of reference images). Other image-to-video models work too; results will differ.

A video editor
CapCut, DaVinci Resolve, Premiere or ffmpeg. You only trim, add captions, add an end card and music.
Step 1Unzip the pack and find these files
The ad uses 8 of the pack's images. Nothing else was uploaded except the product still you make in step 3. Paths are exactly as they appear in the zip.

Step 2Describe the character once
Open 01_character_reference/model_sheet.png and write down what must never change: skin, eyes, hair, outfit and art style. This paragraph goes, word for word, at the start of every message in the steps below (they already include it, so you can copy them as they are). For the video model the opening words become @liu is the same …, which points at the character reference from step 4.
The English text below is the exact prompt used. Copy it unchanged to reproduce the workflow.
Same adult woman as the reference images: warm tan skin, amber eyes, deep navy hair in a high long braid with cobalt-blue tips, small orange earpiece on her left ear, cobalt-blue short-sleeve work polo, black cargo trousers, black jacket tied at the waist, blue-black fingerless gloves. Anime illustration style exactly like the references.

The woman wears the cobalt short-sleeve work polo, never a sleeveless top.
The English text below is the exact prompt used. Copy it unchanged to reproduce the workflow.
no extra people, no text or logos, no outfit change, no sleeveless top, no scene cuts, no camera cuts, correct hands with five fingers, only one earpiece
Step 3Make the product still
Make one picture of the product first. You reuse it for the end cardand as a reference in a shot, so the product looks the same everywhere. Never ask the model to write the brand name; add text in the edit.

Anime illustration product shot in exactly the same art style as the references. One small glossy orange in-ear earpiece, the same shape and colour as the earpiece in her ear in the first reference, lying beside its open matte-black charging case that has a thin cobalt-blue accent line. Centred on a dark charcoal studio surface, soft cobalt-blue rim light, subtle reflection, generous empty space on the left for a title. 16:9 still. No people, no text, no logos.

Step 4Save the character reference for video
In Kling 3.0 we saved these 4 images as one character element named liu with the description below. Every video message then starts with @liu, and Kling keeps the face and outfit from these images. If your video tool has no such feature, skip this step: the first frame and the character description still carry most of the look.

Captions
- Bottom left: 110 px from the left, 170 px from the bottom.
- White, bold italic, 54 px (we used Avenir Next).
- On a rounded black box at about 47% opacity.
- Our “Demo ad · fictional product” label is only there because the products are invented; leave it out of yours.
End card
- product.png for 3.5 s with a slow push-in from 100% to about 110%.
- A near-black gradient over the left 60% so the text reads.
- PITWAVE in bold italic, 130 px; Team Radio Earpiece at 52 px; the tagline at 40 px in #f4f06a.
- The text fades in 0.3 s after the card starts, over 0.4 s.
Music and export
- One track under the whole ad: fade in over 0.5 s, fade out over the last 1.5 s. Use music you have the rights to.
- Export H.264 MP4, 1920×1080.
- The Kling clips are 720p; scaling them to 1080p in the edit is fine for social video.
