Flux 3 AI Video Generator
Multimodal AI Video with Native Audio — Three Ways to Create
Flux 3 is the multimodal generation model from the FLUX family, announced in July 2026 — built to handle video, image, and audio in one unified architecture instead of separate disconnected tools. Turn a text prompt, a single image, or a pair of first and last frames into a polished video with synchronized sound generated alongside the visuals. Choose 720p for speed or 1080p for detail, set durations from 5 to 20 seconds, and pick from eight aspect ratios including adaptive.
Where earlier FLUX releases focused on still images, Flux 3 extends the family into motion and sound, with each modality trained to strengthen the others. On LoveGen AI you can put that to work three ways. Text-to-video generates a complete clip from a written description. Image-to-video animates a starting frame, extending one still into coherent, natural motion. First/last-frame-to-video takes a start image and an end image and interpolates between them, so you control exactly where a shot begins and where it lands. There's no subscription — you pay only for what you generate.
How to Use Flux 3
Step 1: Pick Your Mode
Choose Text to generate from a prompt, Image to animate a single photo, or First/Last to supply a start and an end frame and let Flux 3 interpolate between them.
Step 2: Describe Your Video and Choose Settings
Describe the scene and motion, then set resolution (720p/1080p), duration (5–20s or Auto), aspect ratio, and whether to generate synchronized audio.
Step 3: Generate and Download
Click Generate and Flux 3 will render your video with synchronized audio. Preview it in your browser, then download the MP4 when it's ready.

Why Choose Flux 3
One Multimodal Model
Instead of stitching together separate tools, Flux 3 creates visuals and synchronized sound within one unified architecture — bringing the FLUX family's signature visual quality to motion.
Native Synchronized Audio
Every video ships with AI-generated audio — sound effects, ambience, and speech — aligned to the visuals at no additional cost, on by default and switchable off.
First & Last Frame Control
Supply a start image and an end image and Flux 3 fills in the motion between them — precise control over where a shot opens and where it lands, instead of guessing from a prompt alone.

Flux 3 FAQ
What is Flux 3?
Flux 3 is the newest generation of the FLUX model family, announced in July 2026. Unlike earlier FLUX releases that focused on still images, Flux 3 is multimodal — it generates video with synchronized audio in a single pass. On LoveGen AI you can use it for text-to-video, image-to-video, and first/last-frame-to-video at 720p or 1080p, with durations from 5 to 20 seconds.
How is Flux 3 different from Flux 2 Pro and FLUX.2?
Flux 2 Pro and FLUX.2 are image models — they create still pictures. Flux 3 extends the family into motion and sound: one multimodal model that produces video with synchronized audio. If you need stills, use Flux 2 Pro; when you want those visuals to move and sound alive, use Flux 3.
What input modes does Flux 3 support?
Three: text-to-video (generate from a prompt), image-to-video (animate a single starting frame into natural motion), and first/last-frame-to-video (supply a start image and an end image, and Flux 3 interpolates the shot between them).
Does Flux 3 generate audio?
Yes. Synchronized audio — sound effects, ambience, and speech — is generated with the video by default at no extra cost. You can switch it off if you only need silent footage.
What resolutions, durations, and aspect ratios are available?
Resolutions are 720p and 1080p. Durations run from 5 to 20 seconds, or Auto to let the model decide — first/last-frame mode uses a set duration rather than Auto. Aspect ratios include 21:9, 2:1, 16:9, 4:3, 1:1, 3:4, 9:16, and Auto.
How does pricing work?
There's no subscription — you pay per generation with credits. Cost scales with resolution and duration, so shorter 720p clips cost less than longer 1080p videos.
