A dark glossy horse gallops from right to left in profile against a nearly black studio background. Warm backlight traces its mane and muscles. Smooth lateral tracking, consistent anatomy, rhythmic hoofbeats and soft breathing.
简介
A scene starts with an intention

Example prompts
Wildlife, one continuous shot
Follow a black bear running along a fern-lined trail in a dense evergreen forest, then emerging at the edge of a quiet residential street. Low handheld tracking camera, filtered daylight, audible paws and rustling leaves.
Explain through animation
A handmade illustrated space documentary showing the Sun, Earth and a gold-mirrored space telescope. Move from a wide orbital diagram to a closer view of the telescope and back. Paper textures, deep star field, calm explanatory voice and subtle music.
Light follows movement
A dark glossy horse gallops from right to left in profile against a nearly black studio background. Warm backlight traces its mane and muscles. Smooth lateral tracking, consistent anatomy, rhythmic hoofbeats and soft breathing.
An unexpected physical scene
A small wooden suburban house mounted on heavy wheels rolls across an empty test track and collides with a concrete barrier. Show the structure responding to impact with dust and debris, daylight, a fixed wide camera and synchronized impact sound.

Prepare the right inputs
For video, upload the start frame first and an optional end frame second. For image editing, select the reference images that define your intended result.
Review the exact quote
Resolution, duration and output count determine generation credits. Review the workspace quote before submitting; preparing a prompt does not create a paid task.
Inspect the complete result
Review visual detail, continuity and any generated text before using an output. BFL reference demonstrations and adapted prompts are starting points, not verified reproductions.

常见问题
Frequently asked questions
Is Flux3.tools the official BFL website?
No. Flux3.tools is an independent creative website that connects supported models through fal. Black Forest Labs develops Flux 3.
Does Use This Prompt start a paid generation?
No. It prepares a draft. Review the inputs and credit quote, sign in, and submit when ready.
What happens if generation fails?
A confirmed failed task releases or refunds reserved generation credits. Pending tasks must be reconciled before they can be treated as failed. Cash purchase refunds follow the separate refund policy.
Have keyframes and extension been generation-tested on this site?
Their inputs, provider payloads and quotes have been checked without a paid generation. Actual generated media and paid delivery remain to be verified; reference videos are not proof of these workflows.
