The Cut Is the Interface.
Plan the movement, dialogue and sound across a complete short scene—not only the opening frame.
Generate a Short Scene With Video and Sound in One Workspace.
FLUX 3 Video is Black Forest Labs’ model for creating and extending video. The current GlobalGPT integration exposes a keyframe sequence, continuation from a source video, native-audio controls, 5–20 second durations and 720p/1080p output.
Follow One Scene Through Three Decisions.
This device visualizes one controlled FLUX 3 Video run. It does not claim universal superiority; it shows what happened in a single 10-second output.
Rain · footsteps · bell · dialogue · latch · door hiss
What this run proves—and what it does not.
Same brief, 16:9, 10 seconds, no references, one output each. MiniMax H3 used 768P; the others used 720p.
This is an editorial comparison of three individual outputs, not a scientific ranking. Timings come from one same-batch 10-second test run on 2026-08-19 and are single observed samples, not guaranteed speeds.
Describe the Scene as Visible Beats.
Direct the story first. FLUX 3 Video can generate the picture and native audio together in one result.
Choose the Job
Use a keyframe sequence for a designed transition, or continuation when an existing clip should keep moving.
Order What Changes
Name the opening, main action and final reveal instead of describing one static frame.
Let the Scene Carry Sound
Keep Native Audio on so dialogue, ambience and effects are generated with the video. Specify only the words or sound beats the story must include.
Watch and Listen Once
Check whether the cuts, actions and generated sound agree, then revise the weakest story beat.
Four Ways to Control What Changes Next.
Each example has one proof job, so the media does more than decorate the page.
Hold the Axis Through Transformation.
A fixed theatre composition changes material and atmosphere while preserving the camera line.
Carry Motion Beyond the Source.
Use the existing direction and scene logic as the starting point for the next beat.
Make Lettering Part of the World.
Use signs and printed surfaces as scene elements, then inspect legibility across motion.
Let Action and Sound Agree.
Follow the physical cause and effect: rain, movement and objects produce a connected sound bed.
Three Stories, Built Beat by Beat.
Three complete production situations show how the same progression logic serves explanation, product storytelling and dialogue.
Move from Context to Mechanism.
Start with the presenter, cut to the working detail, then return to the complete idea.
Turn a Product Into an Event.
Move from material detail to human action while sound marks each physical beat.
Let Dialogue Drive the Scene.
Keep voice, mouth movement and room ambience connected to the same performance.
Keep the Scene Moving.
Planning and downstream refinement belong to GlobalGPT’s wider workflow, not to FLUX 3 Video alone.
Use an LLM for dialogue and shot order.
Choose opening and ending constraints.
Generate video and requested sound.
Continue a stronger take or revise one beat.
FLUX 3 Video Questions.
What Is FLUX 3 Video?
FLUX 3 Video is Black Forest Labs' model for creating and extending video with native audio in the GlobalGPT workspace.
How Much Does FLUX 3 Video Cost on GlobalGPT?
The current default is 2,300 GlobalGPT credits for 5 seconds at 720p with Native Audio on. This is a premium-credit configuration, not a low-price option.
How Long Does a FLUX 3 Video Generation Take?
In the 2026-08-19 same-batch test, one 10-second 720p FLUX 3 Video task completed in 186 seconds. This is one observed sample, not a universal guarantee.
What Inputs and Settings Does It Support?
The current GlobalGPT configuration exposes a keyframe sequence, continuation from a source video, 5 to 20 second durations, 720p or 1080p output, and 16:9, 9:16, 1:1, 4:3, 3:4, 21:9 and 2:1 aspect ratios.
How Do I Hear the Generated Audio?
Autoplay previews are muted. Click the Play sound control on a video to hear its audio; only one video plays sound at a time.
Who Should Choose FLUX 3 Video?
Choose it when multi-shot progression, native audio and up to 20-second scenes matter more than the lowest credits. It is not the best fit for budget-first batch experiments or unsupported policy-sensitive content.
