A realistic timeline
- Script (10 to 20 minutes): a hook, one benefit, a call to action. A hook generator speeds this up.
- Presenter (1 to 5 minutes): pick a ready-made AI influencer, or reuse the custom one you already built.
- Product (2 minutes): upload a clean photo of your real product once; it is reused across every variation.
- Generation (a few minutes): the video model renders the clip with motion and lip-sync. Time varies by model and length.
- Review and export (5 minutes): check label, proportions, and audio, then export 9:16 or 16:9.
The first video takes the longest because you are writing the script and setting up the character. Every following variation reuses the presenter and the product, so the marginal time drops to the render time plus a quick review.
What affects generation time
- Model choice: Kreavo routes to Seedance, Kling, VEO, or Wan, and each has its own speed and cost profile.
- Length: a 15-second clip renders faster than a 30-second one.
- Queue: generation runs on shared GPU capacity, so peak times can add a little waiting.
- Extras: face-swap, lip-sync, or editing an existing video with reference images are separate quick steps.
Compared with a human creator
A human UGC creator typically needs 3 to 10 days: agreeing on the brief, shipping the product, filming, editing, and revisions. Revisions are the slow part; each round can add days. With AI UGC, a revision is a regenerate, which takes minutes and costs $1 to $5. That is why AI UGC is used mostly for testing and iteration, where the time between an idea and a live ad matters more than anything else.
How to go faster
Batch your work. Write five hooks at once, generate them in parallel with the same AI influencer and product, and review them together. Keep a saved custom influencer so you never restart character setup. If you use Claude, Kreavo's MCP integration lets you trigger generations from your chat, which removes most clicking from the loop.
