How to make invitation videos with AI
Step-by-step instructions for building invitation videos with current AI models. Covers prompt writing, model choice, audio layering, and export settings that keep the final file under 15 seconds.
TL;DR
Use the text-to-video tool with a 40-word prompt that names the event and colors. Generate an 8-second base clip in Seedance 2.0 or Kling 3.0. Add a music stem and lip-sync layer if needed. Export at 1080p. Total cost stays under 30 credits for one polished file.
The question people usually ask is which button to press first. The one that actually matters is how to keep visual consistency across an event invite while hitting a specific runtime and tone.
Start with a single prompt that names the event, guest count, date, and location. Feed that into the Text to Video tool. Seedance 2.0 handles 8-second clips at 1080p when given a 40-word prompt that lists colors and camera moves.
Picking models that match invitation styles
Kling 3.0 produces smoother motion on static text overlays than Veo 3.1. Wan 2.7 gives sharper background detail for outdoor venues. Test the same prompt across two models and keep the one whose first frame matches your reference photo.
When to switch to motion poster
Use the Motion Poster tool for 15-second loops that repeat a single animated element. It costs 12 credits per export and accepts 1024x1024 stills as input.
Building the script and assets
Write the spoken line first. Limit it to 18 words so it fits inside a 6-second window. Pair it with one hero image that shows the venue or couple.
Upload the image to the Image to Video tool. Set motion strength to 0.65 and duration to 5 seconds. This produces a gentle camera push that feels formal.
Step-by-step generation workflow
- Create an account at the sign-up page and purchase a starter credit pack of 500 credits.
- Open the text-to-video page and paste a prompt that includes event name, date, and color palette.
- Generate three variations and select the one with correct text placement.
- Download the clip and import it into the lip-sync tool if you recorded a voiceover.
- Add background music from the music generation page using a 120 BPM track.
- Export the final file at 1080p and 30 fps.
- Review the file on a phone screen to check text legibility at small sizes.
- Upload the finished video to your event site or messaging app.
Adding sound and final polish
Generate a 10-second music stem with the Music Generation tool. Choose the instrumental option labeled "warm piano" to avoid lyrics clashing with your voice line.
Run the combined video through the Lip Sync Video page when the spoken part needs to match a specific face. Upload a 3-second reference clip of the speaker and set alignment to 85 percent.
Tradeoffs and fixes
| Issue | Cause | Fix |
|---|---|---|
| Text wobbles | Prompt too long | Shorten to under 35 words |
| Colors shift | Wrong model | Switch from Wan 2.7 to Kling 3.0 |
| Audio cuts early | Music longer than clip | Trim music to 8 seconds before export |
| Low credit balance | Multiple test runs | Generate in 720p first then upscale |
Keep one master prompt saved in a note so you can regenerate quickly when the date changes.
The decision rule worth remembering is to lock the visual style with a motion-poster loop before adding voice or music layers.
Frequently Asked Questions
