Generate Video from Prompt (AI) — frequently asked questions

Is Generate Video from Prompt (AI) really free?

Yes, within a daily GPU allowance. Text-to-video is the most expensive thing we run, so every visitor gets a fixed number of GPU-seconds a day (currently 120, about three to four clips) and the jobs queue behind every other tool. When the allowance is used up you can try again tomorrow; there is no paid tier and no watermark.

Which model makes the clip, and is my prompt trained on?

An open-weight text-to-video model (Wan 2.x small, Apache-2.0, or an LTX-class model) on our own GPU worker. Claude models never generate video; they only help write the prompt in the Prompt Enhancer. Nothing is trained on your prompt, and only a salted hash of it is kept for quota counting. The feature ships behind a flag and pauses automatically when the daily GPU ceiling is reached.

Is the AI opt-in?

Yes. A consent sheet appears once per session before any prompt leaves your device. Prompts are moderated before generation (sexual content involving minors, non-consensual imagery, real-person deepfakes, extremist content and hate symbols are refused) and outputs pass a safety classifier. Blocked requests return a plain error; only counts are recorded.

What are the limits of the clip?

2 to 5 seconds, 360p or 480p, 16 or 24 fps, one shot per prompt, MP4 (H.264). For longer pieces generate several clips and join them with Images to Video, or render deterministic title cards with Text to Video Card at full HD.

How long is the clip kept, and how is it labelled?

The clip is stored encrypted for at most 24 hours so you can re-download or Continue with… another tool, then deleted automatically; Delete now removes it immediately. Every clip carries a C2PA provenance manifest stating it was AI generated with Sada Files, with no visible watermark.

Can I chain it with other tools?

Yes. Continue with… hands the clip in memory to Compress Video, Trim Video, Video to GIF or Add Subtitles.
