Process

Five steps to a finished video

We agree on direction before production. Deliverables and revision rounds are set in writing.

  1. STEP 01

    Brief

    Tell us what the video is for, its length, where it will run, your references and your deadline.

  2. STEP 02

    Proposal & quote

    We send a production plan, deliverables, revision rounds and a fixed quote. A deposit starts the project.

  3. STEP 03

    Script & storyboard

    We lock the script and storyboard first, so production starts in the right direction.

  4. STEP 04

    Production & revisions

    AI generation, editing and sound — refined from your feedback within the agreed revision rounds.

  5. STEP 05

    Delivery

    Final files exported to each platform's specs: landscape, vertical and any size you need.

FAQ

Common questions

How is AI video different from a traditional shoot?

There's no location, cast or crew to book, so turnaround is faster and costs are lower — ideal when you need a lot of video, quickly. Where a shot needs to look truly real, we mix in live-action footage.

How long does a project take?

It depends on length and complexity. Image-to-video and short social clips usually take a few days; brand films, animation and series get a timeline in the proposal.

How do you price projects?

Every project gets a fixed quote based on video type, length, quantity and deadline, agreed before work starts. Batch and monthly retainers are priced as packages. We issue contracts and invoices as a US-registered LLC.

How many revisions are included?

Revision rounds are written into the quote. We align on direction at the script and storyboard stage, then refine the final cut within the agreed rounds. Extra rounds are discussed up front.

I only have a few product photos. Can you still make a video?

Yes. That's exactly what image-to-video is for: we turn your product shots, photos or posters into moving footage and add camera motion, music and captions.

Can you help us launch on Douyin, Xiaohongshu or WeChat Channels?

Yes. Creators can usually start with a personal account verified in their own name, and our team in China handles the Chinese versions, posting and day-to-day operations. Brands that want an official business account generally need a company in China. We coordinate company setup through our licensed partners, then set up and run the verified accounts. Every account stays in your name, and the content is reviewed against each platform's rules before it goes live.

Who owns the finished video?

Usage rights are set out in the contract. Any footage, logos or music you supply must be yours to use; the tools and stock assets we use are licensed for commercial use.

Can you make an AI avatar of me, with my own voice?

Yes. Creating a digital twin of a real person's face or voice requires that person's written consent, and we only use it within the scope they approve.
