Localize app UI screens by having the invideo agent analyze the original ad, translate the on-screen UI text into the target language, regenerate each screen as a locked image, then re-animate the screens in the original sequence order. In a documented localization, 5 app UI screens were regenerated per market, holding 100% text consistency across Japan and Spain.
Upload your winning ad to the invideo agent and ask it for a localization plan before touching any screens — the agent watches the video, tells you what stays and what changes, and returns an estimated generation breakdown, including how many app UI screens it plans to regenerate, so you know your rough spend before committing credits. invideo is an agentic video creation tool with all the current image and video models in one place, so the entire UI localization runs in a single session.
1. Lock assets in sequence, with UI screens as their own tier. Work through the approval order characters → locations → clips → UI screens → voiceover, locking each tier before generating the next. A real localization regenerates new character sheets, location sheets, a translated voiceover, and translated in-app UI screens — not a dubbed audio track laid over the old visuals.
2. Translate the UI text and regenerate each screen. The invideo agent translates the on-screen UI text into the target language and regenerates the screens — 5 app screens per market in the documented run. Adapt the copy culturally rather than word-for-word: the documented Japanese version rendered its CTA as "初回購入は最大45%オフ" (up to 45% off on first purchase). For the regeneration itself, GPT-Image-2 is the strongest image model for text and design rendering, and the invideo agent routes UI-screen generation to it without you specifying a model swap.
3. Re-animate the screens in the original sequence order. Keep the edit structure, music bed, and pacing of the winning ad constant — only cast, location, voiceover, and UI text change. The regenerated screens are animated in the same order and beats as the source ad, which is what preserves the original's performance logic. As invideo's team documented: "Most localizations skip this. We didn't."
4. Run three checks before locking. First, if the original reference ad has burned-in captions or overlays, exclude it from generation prompts — the video model will reproduce the old-language text in new clips. Second, keep on-screen text baked into the regenerated image frames rather than asking the video model to render fresh text; text artifacting in AI video is a model-level limitation of Seedance 2.0, not a workflow failure. Third, review each regenerated screen for text expansion (languages like German and French typically run longer than English) and confirm layout direction for right-to-left markets like Arabic or Hebrew before you lock the tier.
5. Decide whether you need translated screens at all. Keeping app UI screens in English is a viable alternative when the app brand is already recognizable in the target market — it skips the regeneration tier entirely.
On cost and time: documented runs landed between $70 and $145 per localized ad — one run cost 570 credits (~$145) per ad including an 85% clip rejection rate, another produced 6 localized ads across Japan and Spain for $425 total ($70 each). The first localization takes about 2 hours; each additional market takes about 1 hour, supporting up to 6 localizations in a single day once the workflow is locked. The Japan and Spain runs were validated across 3 different ads with 100% product and text consistency.
Watch some of these to see what works for you:
Most localizations skip this. We didn't. Agent translated the UI text and regenerated all 5 app screens, then animate them in the same sequence as the original.
