What Is a Sora Prompt Generator and How Do You Use One?

A Sora prompt generator is a tool that turns a reference video — or a set of frames from one — into editable, scene-by-scene text prompts you can paste into an AI video tool. On tubeprompter.com, the Video to Prompt Generator takes YouTube videos and Shorts and produces scene timestamps, start and end frame prompts, and motion directions with camera, lighting, and style details. It fits best when you already have a reference clip whose look you want to reuse, and you need written prompts rather than a vague sense of "make it like this." You need to sign in to use it, and the site states that signing in gives you 5 free analyses per month.

What the generator actually outputs

The tool does not hand you one blob of text. It breaks the reference into parts you can edit separately:

• Scene timestamps — where each scene begins and ends in the source video, so you can work scene by scene instead of describing the whole clip at once.
• Start frame prompt — a description of the first frame: subject, framing, light direction, background, and color.
• End frame prompt — a description of the last frame of that scene, written to stay consistent with the start frame.
• Motion directions — what should change between the two frames: camera moves, subject movement, and how the shot should end.

That split matters because AI video tools tend to handle a still description and a movement instruction differently. Writing them as separate pieces lets you fix one without rewriting the other.

How to convert a reference video into Sora prompts

1. Pick a reference clip with a clear look. A single scene with stable lighting and one obvious camera move analyzes better than a fast-cut montage. The site notes your analysis will depend on your reference.
2. Run the video through the generator. It returns scene timestamps and a pair of frame prompts per scene, plus motion directions.
3. Read the start frame prompt and edit it. Check that the subject, framing, light direction, and background match what you actually want. Swap in your own subject if you're not recreating the original.
4. Copy the start frame prompt into your video tool as the opening description.
5. Add the motion directions. Paste the movement description — for example, a slow camera push toward a detail — and keep the subject fixed if the reference does.
6. Set the shot duration in your video tool. The generator describes the shot; the length is set where you generate.
7. Use the end frame prompt as your target. If your tool supports a start-and-end frame workflow, the end prompt tells you what the final frame should look like.

A worked example from the site's own examples

The product-reveal example describes a matte cream ceramic mug on a warm oak table beside a window: medium close-up at table height, soft daylight from camera left, gentle shadow to the right, muted beige background, no text or logos. The end frame tightens to the handle and rim while keeping the same light, background, and warm colors, and the motion direction is a slow camera push toward the handle with the mug staying still.

Notice what the prompt does not do: it doesn't say "make it cinematic." It names the subject, the framing, the light source and direction, the background, and the color mood. That's the pattern worth copying even when you write prompts by hand.

What to include when you write Sora prompts yourself

Across the site's examples, the same categories keep showing up. Use them as a checklist:

The cinematic-landscape example follows the same logic: a wide view from a rocky ridge at sunrise, dark grass and stones in the foreground, a misty valley in the middle distance, layered blue mountains on the horizon, warm light along the ridge. The end frame moves slightly forward so the foreground rocks sit near the lower edge while the mountain shapes, pale mist, and warm rim of light stay the same.

Common limits and how to work around them

• Reference quality drives output quality. A clip with mixed lighting, heavy cuts, or motion blur gives the analysis less to work with. Choose a clean single scene when you can.
• Free analyses are capped. The site says signing in gives 5 free analyses per month, so spend them on references you actually intend to reuse rather than testing random clips.
• You still have to edit. The prompts are described as editable visual descriptions, not final copy. Expect to swap subjects and adjust style for your own project.
• Duration is set outside the prompt. The generator describes the shot; you set the length in whichever video tool you use.
• Pricing beyond the free tier isn't stated here. The site links to a pricing page, so check there for current terms rather than assuming what's included.

If you want to see the format before committing a reference, the site publishes copyable prompt examples — a product reveal, a cinematic landscape, and a vertical food scene — that you can adapt directly.
