FAQ

Is there a tool that turns one line into a short drama?↓
Yes — OneVideo Studio. Type one line and your AI Director writes the screenplay, casts consistent characters who speak their lines with lip-sync, splits the shots, and delivers a finished vertical short drama for TikTok, YouTube Shorts and Reels. You get 400 free credits on sign-up (about two 15-second films), no credit card.
How is it different from tools that only generate video clips?↓
OneVideo makes a complete film, not a clip collage: the screenplay follows short-drama beats (a 3-second hook, conflict, twist, cliffhanger), characters keep the same face across shots, dialogue is lip-synced, you can regenerate just one shot, and sequel mode continues the story with the same cast.
Is it free to use?↓
Yes. You get 400 free credits on sign-up — about two 15-second short dramas — with no credit card. After that, buy a credit pack when you need one or subscribe.
Which languages are supported?↓
Characters can speak English or Chinese, and captions can be bilingual. The interface is available in both languages too.
Who owns the videos I make?↓
You keep all rights to what you upload and the films you generate (see section 4 of our Terms). Free films carry a OneVideo watermark; paid plans remove it and let you add your own branded end card.
How long does a film take?↓
A 15-second short drama usually takes a few minutes to around fifteen; longer films and busy periods take more. You can leave the page after you hit create and come back when it's ready.
How does pricing work?↓
You pay in credits, and only real AI model calls use them — failed shots are free. A 15-second film is about 200 credits. Plans include monthly credits, and you can top up with a credit pack anytime.
