AI Video Generator FAQ
Answers to 27 common questions about writing scripts, voices and licences, captions, music, formats, processing and privacy.
Getting started
What is AI Shorts Studio?
AI Shorts Studio is an AI video generator that turns a short script into a finished video. It splits your script into scenes, creates a visual for each one, narrates it with an AI voice, adds word-by-word captions and background music, and renders an MP4 file.
Do I need an account or to install anything?
No. The generator runs in your web browser and there are no user accounts. Video generation happens on the AI Shorts Studio server, so you do not need to install any software.
How do I create a video?
Open the AI Video Generator, enter a title and your script, choose a length, format and style, pick a voice, caption style and music, then select Generate Video. When rendering finishes you can preview and download the video.
Scripts and length
How long can my videos be?
You can choose 5, 10, 15, 20, 25 or 30 seconds. Each length has a word budget, and the generator shows your word count and estimated narration time as you type. If a script is too long it is never cut silently. You get a suggested shorter version that you can accept or edit.
How many words fit in each video length?
The narration is paced at up to about three words per second, which gives these limits: 5s: 12 words, 10s: 25 words, 15s: 40 words, 20s: 55 words, 25s: 70 words, 30s: 85 words. Short sentences are easier to follow and leave room for natural pauses.
What happens if my script is too long?
The generator warns you before you start and offers a suggested shorter version. The suggestion keeps your opening sentence (the hook) and your last sentence (usually the call to action), and fills the rest with the sentences that carry the most meaning. You can accept it, edit it or choose a longer video.
How is my script split into scenes?
Your script is divided into 3 to 6 scenes, depending on the length you choose, at natural sentence breaks. Each scene gets its own visual, camera movement and transition.
Which languages are supported?
All of the current narration voices are English voices (US and UK accents), so scripts should be written in English.
Visuals and styles
How are the scene visuals created?
Each scene's visual is generated by the app's built-in visual engine, guided by the keywords in that scene and the colours and mood of the style you choose. Camera motion such as slow zooms and pans, plus transitions between scenes, are added during rendering. No stock footage is used.
What do the visual styles change?
A style sets the colour palette, camera motion, transitions and narration pacing, and picks a matching caption style and music mood. There are 10 styles, from Emotional Documentary and Cinematic Storytelling to Technology Explainer and Product Promotion.
Can I change the captions or music after choosing a style?
Yes. Choosing a style fills in its recommended caption style and music, but you can change either one before generating.
Can I upload my own images, video clips or music?
Not in the generator today. Visuals are created automatically and music is chosen from the built-in moods.
Voiceover, captions and music
How do the AI voiceovers work?
Narration is created with Piper, a neural text-to-speech engine that runs on the server. You choose from the available voices, and the pacing is adjusted automatically to fit your chosen duration. Each voice has its own licence, which is shown when you select it. Check it before using a video commercially.
Can I use the videos commercially?
It depends on the voice. Each voice is trained on a dataset with its own licence, and some, including the Ryan voice, are licensed for non-commercial use only. The licence is shown next to the voice in the generator. Check it, and the Terms of Service, before using a video for commercial purposes.
Are captions added automatically?
Yes. Captions are synced to the narration and highlight each word as it is spoken. You can choose from four caption styles, and an SRT subtitle file can be downloaded alongside the video.
Where do the captions appear on screen?
Captions are placed in a mobile-safe area, above the bottom of the frame where YouTube Shorts, Instagram Reels and TikTok show their own buttons and text.
Can I add background music?
Yes. Pick a music mood, such as soft piano, uplifting, cinematic, tech or corporate, or choose no music. The music is created by the app itself and is automatically lowered under the narration so the voice stays clear.
Formats and downloads
Which video formats are supported?
Vertical 9:16 (1080×1920) for YouTube Shorts, Instagram Reels and TikTok, landscape 16:9 (1920×1080) for YouTube, and square 1:1 (1080×1080) for social feeds. Videos are exported as MP4 files with H.264 video and AAC audio.
What do I get when the video is finished?
An MP4 video at 1080p and 30 frames per second, and an SRT subtitle file with the captions. You can preview the video in your browser before downloading either file.
Do videos have a watermark?
No. The exported video contains only your scenes, captions and audio.
Can I preview my video before downloading it?
Yes. When rendering finishes, the video plays right in your browser. You can then download the MP4 and the SRT captions, regenerate it, or start a new video.
Processing and troubleshooting
How long does it take to generate a video?
Processing time depends on the video length, the format and how busy the server is. Each step (script analysis, scenes, visuals, voiceover, captions and music, and rendering) is shown live, so you always know how far along your video is.
Why is my video waiting in a queue?
The server renders one video at a time, in the order they were submitted. If another video is rendering, yours starts as soon as it finishes.
Can I close or reload the page while a video is rendering?
Yes. Rendering continues on the server. When you open the generator again, a video that is still rendering is picked up automatically, and finished videos are listed in the project library.
What if generation fails?
The generator shows what went wrong and lets you try again with one click. If the problem continues, contact us with the video title and the error message.
Privacy and storage
Where are my scripts and videos stored?
Titles, scripts, settings and generated files are stored on the AI Shorts Studio server so you can preview and download them. Your script is not sent to a paid third-party AI service to generate the video.
Who can see the videos I create?
Videos are listed in the project library in the generator. There are no user accounts, so the library is not private to you. Do not enter confidential or personal information in your scripts, and delete videos from the library when you no longer need them.
