MEET THE MODELS
Get familiar with Flux 3 and Sora 2
Both Flux 3 and Sora 2 generate cinematic video with synchronized native audio, but with different scope. Flux 3 is Black Forest Labs' first fully multimodal model - image, video up to 20 seconds, and native audio from a single prompt in one pass. Sora 2 is OpenAI's flagship video model, built for physically accurate motion and real-world subject injection. Try them both in our AI Playground.
LENGTH, AUDIO & RESOLUTION
Compare clip length, audio, and resolution
Both models reach up to 20 seconds with synchronized native audio - Flux 3 generates sound in the same pass as the video, and Sora 2 delivers synced dialogue and sound effects. On resolution, Sora 2 outputs up to 1080p at 24 or 30fps, while Flux 3 renders high-definition video as part of a single multimodal generation. If you want a defined resolution spec for cinematic clips, Sora 2 is clear; if you want image, video, and audio together, Flux 3 leads.
MULTIMODAL VS CINEMATIC
One-pass multimodality vs cinematic realism
Flux 3's headline is that picture, motion, and native audio come out together in a single pass - not stitched from separate tools - and it accepts text, audio, video, and up to 10 image references for multi-shot storyboarding. Sora 2 focuses on cinematic realism: physically accurate human movement, complex actions, and real-world injection that places real subjects into a scene with accurate appearance and voice.
INPUTS & CONTROL
References, inputs, and creative control
Flux 3 takes up to 10 image references plus text, audio, and video, enabling complex editing, remixing, and multi-shot storyboarding that pure text-to-video models can't handle. Sora 2 works from a text prompt and adds real-world injection, letting you drop real people into AI scenes. Flux 3 offers more input types and shot-level assembly; Sora 2 offers standout realism and subject injection.
PICK YOUR MODEL
Choose Flux 3 or Sora 2 for your workflow
Choose Flux 3 when you want a finished audio-visual moment - image, motion, and sound as one coherent asset - from a single prompt, with references and storyboarding. Choose Sora 2 for cinematic, physically realistic scenes with synced audio and real-world injection. Choose Picsart to use both - generate with Flux 3 and Sora 2 from a single prompt and pick the best model for each project.
