Three honest ways to build one
The fastest route: generate a celebratory backdrop clip, then drop your event text over it in whatever story or video editor you already use — even Instagram's built-in text tools work. The video carries the mood; the text layer carries the facts. This is the recommended path because AI-generated lettering inside video tends to warp, while an overlaid text layer stays perfectly sharp.
The elegant route: design a typographic invitation as a still image first — Nidhogg's Recraft model renders real, clean lettering for names and dates — then animate that still with image-to-video using a very gentle motion prompt like 'soft golden particles drifting, subtle shimmer'. Keep the motion subtle: the calmer the movement, the better the lettering survives. The third route is simply picking an effect preset — CONFETTI RAIN, GOLDEN DUST, SAKURA STORM — and letting it do the celebrating.
Matching the motion to the occasion
Birthdays want energy: bright confetti bursts, balloons, saturated color, a ZOOM PUNCH if the guest of honor has that kind of personality. Weddings and engagements read best in slow motion with warm particles — golden dust, drifting petals, candle bokeh — and a muted, elegant palette. New Year's and milestone parties earn fireworks against a deep night sky.
Color is the fastest way to make it feel designed rather than generated: name your palette in the prompt ('blush pink and champagne gold', 'deep emerald with warm white lights') and match your overlay text color to it. One consistent palette across invite, reminder post, and thank-you clip makes the whole event feel considered.
Sending it everywhere it needs to go
A few seconds of video is a small file, so it travels well — WhatsApp, iMessage, email, a story, or a feed post. Generate square for feeds and chat threads, or make a 16:9 master and use the reframe tool for a 9:16 version that fills the screen as a story. Clips also loop gracefully at this length, which makes the invite feel alive rather than finished.
Put the logistics where they work: the date and place on the video as text, and the RSVP link in the caption or message body, since video itself isn't clickable in most chat apps.
