Nano Banana Wedding Invitation & Save-the-Date AI Posters, Then Seedance-Style Wedding Video

Wedding highlight reels now show up in the same feeds as real ceremony footage. Creators post 8–20 second vows glances, first-dance orbits, and venue walk-ins generated from stills, then ask how to keep the couple recognizable from the invitation to the clip.

That social-proof loop is useful, but it often starts in the wrong place. AI wedding video prompts fail when the faces, outfits, and venue are still undecided. The more reliable path is stills first: a Nano Banana wedding invitation or save-the-date AI poster, then a short, reference-locked hand-off into tools like Seedance, Jimeng, or CapCut.

Why stills first: invitations, seating cards, and storyboard frames

Nano Banana (Google’s Gemini image models) is built for image generation and editing: layouts, readable text, multi-image blending, and subject consistency across revisions. That is the right job for wedding stationery and for the frames you will later lock into video.

Use stills to settle four things before any clip:

1. Couple identity. Approved portraits, hair, skin tone, and defining features.
2. Wardrobe. Dress, suit, flowers, and accessories that must survive every frame.
3. Venue language. Architecture, time of day, florals, and lighting—not a generic ballroom.
4. Type and facts. Names, date, city, and dress code that guests can actually read.

Those stills do double duty. A save-the-date poster can go to print or Instagram. The same approved portraits become identity references for a 4–30 second teaser. Seating cards and table numbers keep the visual system consistent. Storyboard frames mark camera beats so the video prompt is not a paragraph of wishful cinematography.

If you are new to the model, start with the Nano Banana AI image generator guide. For poster layouts and type-heavy designs, use the AI poster design guide. When faces drift between versions, use the character consistency guide.

Copy-ready Nano Banana prompts for wedding stationery

Replace the bracketed fields. Keep one job per prompt: either layout and type, or a portrait/mood frame. Do not ask for a poster and a video storyboard in the same generation.

1. Classic save-the-date poster

Design a print-ready save-the-date poster for [couple names].
Date: [wedding date]. Venue: [venue], [city].
Center a refined typographic lockup with the names, date, and city.
Palette: [ivory, sage, and warm gold]. Paper texture, letterpress feel,
generous margins, no clutter. Include a small line: “Formal invitation to follow.”
Aspect ratio 4:5 for print and Instagram. Keep all text sharp and spelled exactly.

2. Illustrated wedding invitation suite cover

Create a wedding invitation cover illustration for [couple names].
Venue landmark: [venue feature, e.g. stone chapel / courtyard fountain].
Style: fine-line botanical illustration, muted watercolor wash, cream stock.
Leave a clean type area for “Together with their families” plus the names,
[wedding date], and [venue]. Do not invent extra names or a monogram.

3. Portrait-locked stationery hero (upload approved photos)

Image 1 and Image 2 are identity references for [partner A] and [partner B].
Preserve both faces, hair, age, and proportions. Do not beautify into different people.
Place them in a half-length portrait suitable for a save-the-date poster.
Wardrobe: [dress description] and [suit description]. Setting: [venue garden at golden hour].
Soft natural light, shallow depth of field, elegant but documentary—not fashion-editorial.
Leave negative space at the top for later type: [couple names] and [wedding date].

4. Seating card and table number set

Design a matching pair: one seating card and one table number.
Event: wedding of [couple names] at [venue].
Card text: “[guest name]” and “Table [number]”.
Table number: “Table [number]” only.
Shared system: [serif typeface mood], [palette], thin gold rule, linen texture.
Same margins and ornament scale on both pieces. No extra icons or slogans.

5. Ceremony storyboard frames (stills, not video)

Using the couple identity from the approved portraits of [couple names],
generate 6 storyboard stills for a wedding teaser, 16:9, consistent faces and wardrobe.
Beats: (1) arrival at [venue], (2) aisle walk, (3) vows glance,
(4) ring exchange close-up of hands only, (5) first-dance start,
(6) exit under [sparklers / petals / dusk courtyard].
Same lighting language and venue architecture in every frame.
Do not change identity, outfits, or season between frames.

6. Evening reception mood frame

Create a cinematic still of [couple names] at their reception in [venue].
Identity locked to the approved portraits. Wardrobe unchanged.
Candlelight, practical warm fixtures, shallow focus on the couple,
background guests implied not portrait-sharp. Vertical 9:16 for stories.
This is a mood frame for video planning, not a poster, so omit large type.

7. Bilingual or two-city save the date

Design a bilingual save-the-date poster for [couple names].
English line: [Save the Date / wedding date / venue / city].
Second language: [exact text provided—do not translate or invent].
Equal visual weight for both languages. Shared palette [colors].
No decorative script that breaks accent marks. 4:5, print-safe margins.

8. Program insert / timeline card

Design a wedding-day timeline card for guests of [couple names].
Venue: [venue]. Times exactly as given:
[3:00 pm ceremony], [3:45 pm photos], [5:00 pm cocktail hour], [6:00 pm dinner].
Clean two-column layout, high-contrast type, no script fonts for times.
Match the invitation suite palette. Leave a footer: [hashtag or website].

Hand-off: approved stills into Seedance-style 4–30s clips

Once the invitation suite and portraits are approved, treat video as a reference-locked job, not a new character design.

Tools in this class—Seedance 2.5-style generators, Jimeng, or CapCut AI clips—typically take image (and sometimes video/audio) references and produce a short clip, commonly in the 4–30 second range per generation. That is enough for one beat. It is not a replacement for a 20-minute highlight film. If a tool offers extensions, treat each extension as another continuity risk: keep the same identity stills attached.

What to upload

Reference	Controls	Must not control
Approved couple portraits	Faces, hair, age, proportions	New wardrobe or a different venue
Outfit stills or invitation hero	Dress, suit, florals, accessories	Different people
Venue photos or Nano Banana venue frames	Architecture, time of day, palette	Couple identity
Optional motion or camera still	Orbit, push-in, or handheld energy	Faces or clothes

Give each file one sentence of role. Example: “Images 1–2 lock couple identity. Image 3 locks the courtyard at [venue]. Ignore faces in the venue photo.”

Write one beat, with a timestamp

Keep the prompt to a single action and a clock. Name the shot size and the camera path. State the hold on identity at the end.

Vows glance (about 6 seconds)

Duration: 6 seconds. 16:9, documentary wedding coverage.
0.0–2.0s: medium close-up of [partner A] during vows at [venue].
2.0–4.5s: cut or gentle pan to [partner B] returning the glance.
4.5–6.0s: two-shot, hands visible, no invented guests in focus.
Lock faces and wardrobe to the approved portraits. Lock architecture to the venue refs.
Natural ceremony audio only if the tool supports it; otherwise silent picture.
No slow-motion faces, no beauty-filter skin, no text overlay.

First-dance orbit (about 12 seconds)

Duration: 12 seconds. 16:9. Reception floor at [venue].
0–3s: wide, couple in hold, string lights practical in background.
3–9s: slow orbital move around [couple names], one continuous take.
9–12s: settle on a two-shot, faces readable.
Identity and outfits locked to approved stills. Do not change the dress silhouette.
Camera: stable orbit, not a drone crash-in. No extra dancers in the foreground.

Venue walk-in (about 8 seconds)

Duration: 8 seconds. 9:16 for stories.
0–8s: one continuous walk up the path or steps of [venue] at [golden hour / dusk].
Couple identity locked to approved portraits. Wardrobe unchanged.
Architecture must match the venue references. No substitute landmark.

Ring close-up (about 4 seconds)

Duration: 4 seconds. Extreme close-up of hands exchanging a band.
Use the hand shape and skin tone from the approved portraits; do not invent jewelry brands.
Soft ceremony light. No faces required in frame. Hold identity via wardrobe cuff / sleeve detail.

Generate each beat separately. Review faces before you extend or stitch. Assemble the teaser in an editor (CapCut or any NLE) rather than asking one prompt for “our whole wedding film.”

Capability, not marketing: reference-heavy video models can hold a look when the stills are clear and the prompt is narrow. They still drift on teeth, earrings, venue signage, and crowd faces. Budget time to reject clips the same way you reject poster drafts.

Tools and next guides

Stay on this site for the stills half of the job:

• What Nano Banana is and how to generate or edit images
• AI poster design with Nano Banana
• Copy 8 Nano Banana editing prompts
• More copy-and-use Nano Banana prompt suggestions
• Keep the same faces across new poses
• Portrait lighting and identity prompts

For the motion half, use whatever video tool you already have access to—Seedance-style generators, Jimeng, CapCut, or a similar reference-to-clip workflow. If you write many clip prompts, a dedicated video prompt builder can help you keep duration, camera, and reference roles in one place. This site does not sell those builders; use one only if it saves you from rewriting the same identity lock every time.

Disclaimer

Get consent before you upload or generate anyone’s face—partners, family, wedding party, or vendors. Do not treat an AI likeness as cleared for ads, vendor portfolios, or public posts without agreement. Do not invent real people’s faces for “sample guests.”

AI stationery and short clips are planning and social tools. They are not a substitute for professional wedding photography or videography, legal name spellings on printed suites, venue rules, or the audio and coverage of a real day.
