Product basics
Tweenr is an AI animation asset generator for pro video editors. Describe a small motion element in plain English or 繁體中文, get a production-ready MP4 in under a minute, drop it into your Premiere / After Effects / CapCut timeline.
You already use Premiere, After Effects or CapCut, and you need small animated elements — loading bars, typing text, glowing CTAs, notifications, chart reveals — without spending 30 minutes hand-animating each one.
Tweenr is a generator, not an editor. Its output is a standard MP4 file that drops into whatever timeline you already use. We don't try to replace your editor — we fill in the gap where you'd otherwise spend half an hour in After Effects.
Three differences. (1) Traditional Chinese is native — 繁體中文 fonts render perfectly at export time, no tofu boxes. (2) We self-host the render pipeline for better pricing. (3) We're building toward transparent export formats (ProRes 4444, WebM alpha) that drop cleanly onto an AE / Premiere alpha layer.
Using Tweenr
No. Describe what you want in plain language. Adjust colors, timing, fonts with sliders afterward. If you can brief a junior designer, you can use Tweenr.
1080p H.264 MP4 today — drops into any video editor. ProRes 4444 with alpha channel, PNG sequence and WebM alpha are on the roadmap for Pro tier.
Trust & money
Your projects (prompts, generated code, exported videos) are stored in your account so you can come back and edit them. You can delete a project permanently at any time. We never train AI models on your prompts, code or outputs.
Yes. You own every scene you create and every MP4 you export. Use them in client work, YouTube videos, ads, anything.

Comparisons
How is Tweenr different from Runway?+
Runway is a video diffusion model — it generates pixels frame-by-frame, which is powerful for cinematic B-roll but unpredictable for text, UI, and precise motion. Tweenr generates motion-graphics code (Remotion) which renders deterministic MP4s: same prompt gives the same frame every time. Text stays sharp, brand colours stay exact, and you can fine-tune with sliders instead of re-prompting. Use Runway for realistic clips, Tweenr for product shots, title cards, kinetic type, and UI demos.
What about Pika or Sora?+
Same story as Runway — diffusion-based, great for dreamy cinematic shots, not reliable for reading text or keeping a brand colour exact across frames. Tweenr is code-rendered, so if you need a 3-second scene that ends on your exact HK$388 price pill with your exact brand #CE1141, you'll get it every render. Pika and Sora shine for imagined live-action; Tweenr for designed motion-graphics.
