Question 1

Is Shorts Studio really free?

Accepted Answer

Yes. Shorts Studio is 100% free. There is no signup, no paywall, and no API keys to buy. All AI generation runs through free public providers (Pollinations, Lexica) and on-device Whisper for captions.

Question 2

Do I need to install anything?

Accepted Answer

No. Shorts Studio runs entirely in your web browser — Chrome, Edge, Firefox, or Safari. Your videos are rendered locally and never uploaded to a server.

Question 3

What video formats does it export?

Accepted Answer

Shorts Studio exports WebM (VP9 + Opus) at 1080p. WebM uploads directly to YouTube. For Instagram or TikTok, convert to MP4 with a free tool like CloudConvert.

Question 4

Which aspect ratios are supported?

Accepted Answer

Five ratios: 9:16 (YouTube Shorts, Reels, TikTok), 16:9 (YouTube landscape), 1:1 (Instagram square), 4:5 (Instagram portrait), and 4:3 (classic).

Question 5

Are my files private?

Accepted Answer

Yes. Audio, images, and transcripts never leave your device. Whisper runs locally, the canvas renders locally, and the WebM file is created on your machine. The only network calls are to fetch AI-generated images and the Whisper model itself.
