Turn one idea into a finished, narrated video
The AI video generator is the fastest way to go from an idea to an MP4. Give it a topic, paste a script you already wrote, or upload an audio recording. The studio writes or keeps the narration, splits it into scenes, creates a visual for each scene, records the voiceover and burns in captions, then assembles everything into one video.
Choose widescreen 16:9 for YouTube and websites, or vertical 9:16 for phones. The length, visual style and voice are set before generation, so the first result is already close to what you want, and every finished video lands in your library ready to translate, reframe or publish.

Frequently asked questions
Do I need to write a script?
No. A topic is enough; the studio writes the script. You can also paste your own script or upload audio instead.
Which formats can I export?
An MP4 in 16:9 widescreen or 9:16 vertical, with captions included.
Can I change the video after it is made?
Yes. From the library you can translate it, dub it, reframe it to another shape, shorten or lengthen it, or publish it.
