Draft mode renders at 720p preview resolution with faster turnaround and substantially lower credit cost, making it ideal for checking camera velocity, shot pacing, and audio timing. Standard mode delivers full-fidelity 1080p output with refined surface micro-textures and pristine dynamic motion for client-ready delivery. ### When should I choose first-and-last frame mode over standard text-to-video? Use text-to-video when generating an entirely new scene from scratch. Use first-and-last frame mode when you have two distinct reference images and need deterministic interpolation between them—such as building seamless looping clips with identical start and end frames, or guiding a deliberate visual transformation across 5 to 20 seconds. ### How does video extension work? Extend mode takes an existing video clip and generates the next sequence of continuous action. To maintain visual continuity, provide stable base footage without hard cuts and describe the subsequent narrative progression and acoustic environment clearly in your prompt. ### Does the model generate synchronized audio natively? FLUX.3 synthesizes visual frames and synchronized auditory latents together in a single foundation architecture. Describing concrete acoustic details—such as mechanical hums, footsteps on gravel, or room reverberation—steers the native audio generator to match on-screen physical dynamics. ### Who created FLUX.3 and when was it released? FLUX.3 was created by Black Forest Labs and introduced in mid-2026 as a unified multimodal foundation model for 5 to 20 second video generation. ## Try FLUX.3 on Fuser Direct multi-second cinematic sequences with synchronized atmospheric audio, deterministic keyframe interpolation, and seamless video extensions [Direct cinematic scene](https://app.fuser.studio) ## Related models - [Kling O3](https://fuser.studio/models/kling-o3.md) - [Kling O3 Edit](https://fuser.studio/models/kling-o3-edit.md) - [Kling 3.0 Video](https://fuser.studio/models/kling-3-0-video.md) - [Seedance 2](https://fuser.studio/models/seedance-2.md) - [MiniMax H3](https://fuser.studio/models/minimax-h3.md) - [Grok Imagine](https://fuser.studio/models/grok-imagine.md) Node reference: [FLUX.3 Video docs](https://docs.fuser.studio/docs/nodes/video/flux-3-video.md) ## More articles - [FLUX.3 Image Prompt Guide: Text, Layout Boxes and 4K](https://fuser.studio/articles/flux-3-image-prompt-guide.md) - [First and Last Frame Video: How to Generate a Clip Between Two Images](https://fuser.studio/articles/first-last-frame-video-guide.md) - [How to Make AI Videos Longer: Extend, Chain and Multi-Shot](https://fuser.studio/articles/extend-ai-video-length.md)
