Made with this app
FLUX 3 is a text-to-video app that generates between 5 and 20 seconds of 1080p video with native synchronized audio, built for creators who need precise control over how a scene unfolds. You can drive it with a written prompt, a single source image, a start and end frame it interpolates between, or a keyframe timeline with up to 10 pinned moments. A Draft Preview mode lets you validate your setup before committing to a full render.

What you can make
Product Reveal Transitions
Supply a closed-box image as your start frame and an open, lit product shot as your end frame. FLUX 3 interpolates a smooth reveal between the two, producing a polished 1080p clip with ambient audio ready for a product page or social ad.
Keyframe-Timed Narrative Sequences
Pin up to 10 keyframes at the exact moments you choose along the timeline, letting FLUX 3 build connective motion between each beat. This is useful for explainer videos, brand stories or music-synced visuals where specific images must land at specific times.
Long-Take Cinematic Shots
At up to 20 seconds, FLUX 3 supports the kind of extended single-shot footage that shorter video models cannot sustain. A slow aerial drift over a landscape, a long dialogue setup or an evolving abstract sequence all benefit from the extended duration.
Animating Still Photography
Feed a high-resolution still photograph as the source image and describe the motion you want. FLUX 3 breathes life into architecture, portraits or product photography, outputting a 1080p MP4 with synchronized audio rather than a silent loop.
Draft Validation Before Full Renders
Before investing in a full 1080p generation, run your prompt or keyframe setup through Draft Preview mode to check composition, motion direction and pacing. Catching a misaligned keyframe or wrong aspect ratio at draft stage avoids wasting a full render.

Tips for better results
Use Draft Mode First
Before running a full 1080p generation, send your prompt or keyframe setup through Draft Preview mode. It renders at a fraction of the cost and reveals motion problems, wrong framing or misread prompts early, so your full render is more likely to land correctly the first time.
Anchor Keyframes to Audio Beats
Because FLUX 3 generates native synchronized audio, placing keyframes at moments that correspond to audio events creates natural-feeling cuts and transitions. Describe the sound you want near each keyframe in your prompt to help the model align visuals and audio.
Match Aspect Ratio to Platform Early
FLUX 3 supports 8 aspect ratios. Choosing the correct one before generating, rather than cropping afterward, preserves full 1080p resolution and avoids reframing that cuts off subjects. Decide on your delivery platform before you write the prompt.
Give Start and End Frames Clear Visual Distance
The start-to-end-frame interpolation works best when the two frames are visually distinct but share enough compositional logic for a coherent transition. Frames that are nearly identical produce flat motion; frames with no shared elements can produce incoherent morphing.
When to choose this app
Choose FLUX 3 when you need precise timeline control, start-to-end-frame interpolation, or keyframe-pinned sequences that other apps do not offer structurally. Seedance 2.5 bills by area and extends to 30 seconds, which suits different pricing and duration needs, while Sora 2 focuses on physical coherence without the keyframe timeline FLUX 3 provides. If your brief demands a specific image at a specific moment in the video, FLUX 3 is the right tool.
Frequently asked questions
What input types does FLUX 3 accept?
FLUX 3 accepts four input types: a text prompt alone, a single source image you want animated, a pair of start and end frames it interpolates between, or a timeline of up to 10 keyframes each pinned to a moment you choose. These can be used independently or in combination depending on your workflow.
How does the keyframe timeline work?
You pin up to 10 images or visual descriptions to specific timestamps along the video timeline. FLUX 3 generates the motion and transitions between each pinned point automatically. This gives you control over what the video looks like at chosen moments without manually animating every frame.
What does native audio mean in practice?
Native audio means FLUX 3 synthesizes a synchronized audio track as part of the same generation pass, rather than adding silence or requiring you to attach audio separately. The sound, whether ambient noise, music or effects, is generated to match the visual content described in your prompt.
When should I use Draft Preview mode?
Use Draft Preview any time you are working with a new prompt, an untested keyframe sequence or an unfamiliar aspect ratio. Draft mode renders at reduced cost and lets you confirm motion direction, subject framing and pacing before committing to a full 1080p output.
Can I control the video duration precisely?
You can set duration anywhere between 5 and 20 seconds. Shorter durations suit single-moment animations or tight social clips; longer durations support extended cinematic takes, evolving sequences or anything requiring sustained motion that shorter video models cannot accommodate within one clip.
What aspect ratios are available, and does the choice affect resolution?
FLUX 3 supports 8 aspect ratios covering common delivery formats from landscape to portrait. Selecting the correct ratio at generation time means the full 720p or 1080p resolution is used within that frame shape. Cropping a generated video to fit a different ratio afterward reduces effective resolution and may reframe subjects.
Which AI model powers this app?
This app runs on FLUX 3, available through Arteza with no separate account or setup.
Can I use the results commercially?
Yes. Content you generate is yours to use, subject to our content licenses.
How long does a generation take?
Most generations finish in under a minute, and you can watch progress live in the gallery.
