AI VIDEO GUIDE · Process & timing

How long does it take to make an AI promo video?

Short answer

For a 1–2 minute AI promo video, the first cut usually takes about a week and revisions to final take about another week, so from brief to delivery is roughly two weeks when things go smoothly. If you only want to check direction first, a sample demo of 15 seconds or more can be ready as soon as the same day. Projects with many approval layers, longer runtimes or multiple episodes are scheduled by shot count when the contract is signed. Rush production is available; timeline and price are agreed case by case.

A typical schedule

“First cut in about a week” means a complete version: video generation, editing, AI voiceover, music, sound effects and subtitles are all done, not a picture-only rough cut.

  • Brief: about 1 day; assessment and quote: 1–2 business days
  • Work starts as soon as the deposit arrives
  • After script, style assets and storyboards are approved, the first cut takes about a week
  • About one more week of revisions to final
  • Sample demos start at 15 seconds and can be ready the same day
  • Rush production is available; timeline and price are agreed case by case.

What makes it faster or slower

What affects the schedule most is usually not runtime but how quickly approvals come back and how many layers review the work. Please send consolidated feedback within 2 business days at each checkpoint; if a reply is late, the delivery date moves back accordingly. Projects where the contact can make the call move fastest; when feedback has to pass through several layers, we leave room for extra review rounds.

Visual difficulty matters too. Dialogue lip sync, continuous storylines, complex action and exact product reproduction need multiple generations to pick the best take, which takes more time.

How long real projects took

These timelines come from our case study pages; schedules vary with the type and length of the film:

  • UNDP public-interest animation: 1:42 vertical, 7 days from brief to release
  • Kuaishou E-commerce booth film: requested three days before the show, 41-second film made in one day
  • OHMAI (UK) product film: under two weeks from the kickoff chat to the 4K English film
  • BGI Genpilot launch film: 32:9 wide screen, 16 days
  • NDRC 24 Solar Terms: most episodes took 5 to 11 days
  • Kuaishou 2026 CNY micro-drama: 7 minutes in several versions, about two months

What if you have a fixed release date

If you have a fixed release date and the window is about two weeks or less, you can choose deadline-based revisions at signing: we revise as many times as we can within the window and deliver the best version on the date. For example, brief on October 15 for a conference on the 30th means two weeks of full support without counting rounds.

Series and longer films are scheduled by episode or segment, and several teams can work in parallel.
