Veo 3 Prompt Generator From Video

Write a Veo 3 prompt from a clip

Upload a clip and ShotPrompt writes a Veo 3 prompt from it, together with timed shot cards. Veo 3 can generate sound with the picture, so prompts for it often carry audio instructions as well as visuals. The tool reads frames only, so audio is the part you add.

A structure for Veo 3 prompts

Veo prompts are easier to control when each sentence has one job. A common order:

Cinematography: shot size, angle and camera move, for example “slow dolly in, medium close-up”.
Subject: who or what, with the details that identify them in this shot.
Action: what happens, in the order it happens.
Context: the place, the time of day and the weather.
Style and mood: film look, color, lens feel and pace.
Audio: dialogue, sound effects, ambient sound and music.

Writing the audio line

What you want	How to write it
A spoken line	Put the words in quotation marks and say who speaks: a woman says, “We should go.”
Sound effects	Name the sound and its source: a door slams, footsteps on gravel
Ambient sound	Describe the room tone: distant traffic, wind in the trees
Music	State the genre and mood, or say there is no music
Silence	Write it out, so the model does not fill the gap

Because ShotPrompt cannot hear your clip, treat any audio line in its output as a placeholder and replace it with what you want.

From shot cards to a Veo 3 prompt

Split the clip by its time codes and write one prompt per shot rather than one prompt for the whole minute.
Copy the camera and lighting lines from each card into the cinematography and style parts.
Repeat a character description word for word across shots so the subject stays consistent.
Use the JSON tab if you keep shots in a spreadsheet or a script.

A worked example

This is an illustration, not output from a real clip. A shot card might read: 0:00–0:04, a cyclist rides toward the camera on a tree-lined road, low angle, low sun from behind. As a Veo 3 prompt that becomes:

Low-angle static shot. A cyclist in a yellow jacket rides toward the camera on a tree-lined road. Low evening sun from behind, long shadows, warm color. Calm pace. Audio: tires on asphalt, birdsong, no music.

The card supplied the shot, the subject and the light. The audio line was added by hand.

Common mistakes

Stacking several actions in one shot, which makes the order unclear.
Using a word such as “cinematic” without saying what you actually see.
Leaving the audio out and letting the model decide.
Changing a character’s description between shots.

Limits

The prompt describes what appears in the frames. It is a starting point, not a promise of a matching video, and the same text can come out differently from one run to the next.
