How to Create an AI Dynamic Banner Bio

What you will build

Dynamic banners are one of the most effective ways to bring an vivid profile page to life. Instead of a static photo, imagine a looping video portrait at the top of the page, paired with a curated nine-image grid that captures the idol’s unique vibe. In this tutorial, you’ll learn how to create exactly that: a modern idol bio page that blends cinematic visuals with interactive design.

To achieve this, we’ll work inside Trickle, the agentic canvas built for vibe coding. Trickle combines AI-powered image and video generation with design tools, letting you move from still portraits to motion banners in a seamless workflow. With built-in models like Nano Banana for fast image prototyping, Seedream 4.0 for high-fidelity image-to-video generation, and Seedance 1.0 Pro for cinematic animation, Trickle gives you everything you need to turn static assets into immersive, production-ready visuals.

Model overview and when to use each

Nano Banana

Fast image generation and style exploration. Ideal for turning a provided idol reference into a polished portrait and for creating matching visual variations for the nine-grid set.

Seedream 4.0

High-fidelity generation with strong prompt following. In this workflow you can use Seedream 4.0 both to refine stills and to generate short portrait videos when you need higher consistency from image to motion.

Seedance 1.0 Pro

Image-to-video or text-to-video with smooth, cinematic motion. Useful for bringing a still portrait to life with natural breathing, hair micro-movement, or a gentle camera drift for a premium banner feel.

Tip for consistency

Pick one lighting palette and a few style tokens and reuse them in every step. For example dark red ambience, cinematic lighting, moody tone, shallow depth of field. This keeps the banner and the grid coherent.

End-to-end tutorial

Step 1 Prepare your references and style tokens

• Choose one strong waist-up idol reference that you are allowed to use.
• Define your style tokens once. Example red ambient light, cinematic shadows, soft bokeh, UHD, 9 by 16 portrait.

These tokens will appear in every prompt so the banner and grid feel like one brand.

Step 2 Generate the hero portrait in Trickle

1. In Trickle select Generate Image.

2. Provide your idol reference and describe the portrait succinctly with your style tokens.

   

3. Review the result and regenerate if skin texture, hair edges, or lighting do not match your target.

4. Save the selected portrait to Library and name it idol_hero_still.

Quality checklist

• Face is crisp and on-style
• Shoulders and outfit read well at 9 by 16
• Background glow and color match your planned UI accent

Step 3 Create the nine-image “My Vibe” grid

1. Still in Generate Image, ask for nine images that share the same style tokens and color palette as the hero.
2. Specify variety across three buckets
   • Objects that match stage vibe jewelry drink glass accessories
   • Atmospheric scenes city night neon textures
   • Occasional human figure details hands silhouette profile
3. Save each image individually to Library and rename them vibe_01 … vibe_09.

Curation tip

Lay the nine images side by side in the Library preview and remove any that fight the hero color temperature. Replace those until the grid reads as one moodboard.

Step 4 Animate the hero for the banner

Now that you have a strong portrait still, the next step is to bring it to life. Inside Trickle, choose Generate Video and use the portrait (idol_hero_still) as your base. Keep the motion subtle: a gentle head turn, natural breathing, slight hair movement, or a slow camera push. Aim for a short 3–6 second clip so the banner loops smoothly without feeling repetitive.

When the video finishes rendering, it will appear in your global Library. Rename it idol_banner_video so it’s easy to reference later.

Looping tip

When writing your instructions, ask for the first and last frames to stay visually similar in pose and lighting. This makes the loop feel continuous and seamless.

Step 5 Build the page on Magic Canvas

1. Open Magic Canvas and start a new canvas.
2. In natural language, lay out the hero section
   • Place a full-width video banner that preserves a 9 by 16 portrait inside a responsive container.
   • Use the Library asset named idol_banner_video.
   • Mute by default and loop.
   • No borders shadows or rounded corners.
3. Add the left panel for the name
   • Two lines of text Korean name on top English name below.
   • Use the Caveat font for headings and ensure good contrast against the dark UI.
4. Add the right panel image fallback
   • If the video is still loading, show idol_hero_still as a temporary poster frame.
5. Create the “My Vibe” grid under the hero
   • A 3 by 3 responsive grid.
   • Fill cells with vibe_01 … vibe_09.
   • Use subtle hover to scale up by a few percent and reveal a thin border in neon green.

Copy-ready vibe coding instructions you can paste in sequence

• “Create a hero section with a two column layout. Left column is text, right column is media.”
• “Insert a full width video player in the right column. Source is Library.idol_banner_video. Loop and mute. No decoration.”
• “Set a poster image using Library.idol_hero_still.”
• “In the left column add H1 and H2 lines for the name. Font family Caveat for both. Align vertically centered.”
• “Under the hero add a section titled My Vibe. Add a 3 by 3 grid. Fill each cell with Library.vibe_01 to Library.vibe_09. Add subtle hover scale and a one pixel border using #c4f82a.”
• “Use a dark UI background #0c0c0c with layered grays #1a1a1a and #2a2a2a. Accent colors #c4f82a #84cc16 #22c55e.”

Step 6 Polish for performance and accessibility

• Use the video in H264 or H265 at a sensible bitrate so it loads quickly on mobile networks.
• Provide descriptive alt text for the hero video and each grid image.
• Ensure focus styles and keyboard navigation work on all interactive elements.
• Test on mobile and desktop to confirm the banner scales gracefully.

Prompt blueprints you can reuse

Keep prompts modular and variable driven. Below are abstracted templates rather than full prompts.

Hero portrait template

Goal create a waist up idol portrait that matches [lighting palette] with [mood tokens]. Emphasize [facial qualities]. Keep background minimal and cinematic. Aspect 9:16. Ultra clean skin and hair edges.

Nine-grid set template

Goal produce nine images that share the same style tokens as the hero. Mix three categories objects atmosphere occasional person. Keep color temperature and lighting consistent. Output nine separate images.

Portrait to video template

Goal animate the hero portrait with subtle motion for a seamless looping banner. Keep framing consistent. Add gentle breathing hair micro movement and a slow camera push. Duration 3–6 s. Loop friendly endpoints.

Magic Canvas wiring template

Place full width looping video banner using [asset_name]. Add poster image [still_asset]. Left column shows [korean_name] and [english_name] with Caveat font. Add My Vibe grid and fill with [vibe_assets]. Use dark UI palette and neon green accents.

Replace bracketed variables with your choices to maintain speed and consistency across projects.

Why this matters

A living banner communicates brand and personality in the first second. By turning a still portrait into a tasteful motion loop, you deliver higher perceived production value and longer on-page attention. The Library-first workflow in Trickle keeps assets organized so you can remix the same hero video across profile pages, press kits, and showcase reels without rebuilding the layout.

Publishing checklist

• Portrait and banner share the same lighting and palette
• Banner loops cleanly and remains muted by default
• Names render correctly in Caveat and fall back to a system font if unavailable
• Nine-grid images are compressed and color matched
• Mobile layout shows the name and banner without overflow
• All assets are clearly named in Library for future reuse
