0%FLUX.3 by Black Forest Labs is now available in Starpop. You can turn a prompt into a new video, animate an existing image, or control both the opening and closing frame of a clip.
The same model is available in Create video and Starpop's AI chat, so you can build the generation directly or ask chat to prepare a draft for you.
Three ways to start
- Text only: Write a prompt and let FLUX.3 create the scene from scratch.
- Start Frame: Add one image to preserve its subject, composition, or product while directing the motion in your prompt.
- Start and End Frames: Add both images when the clip needs to begin and finish in specific visual states.
An End Frame can only be added after a Start Frame. Choose two frames with compatible subjects and composition so the transition has a clear visual path.
How to create a FLUX.3 video
Open Create video
In your Starpop workspace, select Create video, open the model picker, and choose FLUX.3 from Black Forest Labs.
Write the prompt
Describe the visible action, camera movement, pacing, and sound. If the video includes dialogue, write the exact words in quotation marks.
Add frames when you need control
Leave the frame area empty for text-to-video, add a Start Frame to animate one image, or add both a Start Frame and End Frame to direct the transition.
Choose the output settings
Set the aspect ratio, 720p or 1080p resolution, a duration from 5 to 20 seconds, and the number of videos. Keep Generate Audio on for native sound, or turn it off for a silent clip.
Generate the video
Select Generate video. The credit total updates before you start, and the finished generation appears in your workspace.
Output options
FLUX.3 supports eight aspect-ratio choices: Auto, 21:9, 2:1, 16:9, 4:3, 1:1, 3:4, and 9:16. You can generate clips from 5 to 20 seconds long at 720p or 1080p and request up to 10 variants in one run.
Generations cost 1.7 credits per second at 720p or 2.9 credits per second at 1080p. The cost shown on the button reflects the selected resolution, duration, and number of videos.
Where FLUX.3 helps most
Animate a product shot: Start from an approved product image and describe only the movement, camera, lighting, and audio that should change.
Control a visual transition: Use first and last frames for a reveal, before-and-after moment, environment change, or planned final composition.
Explore from a prompt: Start without frames when composition can stay open and you want to compare several visual directions quickly.
Use FLUX.3 in chat
FLUX.3 is also available to Starpop's AI agent. Ask chat to use FLUX.3, describe the clip, and identify any selected images that should become the start and end frames. Chat can stage the prompt, settings, references, and variant count for you to review before generation.
