About this model
FLUX 3 Video Upscaler raises FLUX 3 (or any) video output beyond its native resolution, preserving motion coherence and native audio sync while sharpening detail — useful since FLUX 3 Text to Video and FLUX 3 Image to Video launch capped at 1080p. Choose a creativity level to balance fidelity to the source against additional detail reconstruction, and an upscale_factor to control how much larger the output becomes.

Provide a source video via video_url — any MP4, including FLUX 3 Video output.
Optionally add a prompt describing the desired enhancement direction, detail style, or visual refinement.
Set upscale_factor (1–4×) to control how much larger the output becomes.
Choose creativity — 0 (Precise) stays closer to the source, 1 (Creative) reconstructs more detail at a higher price.

It raises any video's resolution beyond its native output, preserving motion coherence and native audio sync while sharpening detail.
Precise (`creativity: 0`) stays closer to the original source and costs $1.43 per run. Creative (`creativity: 1`) reconstructs more detail and costs $2.00 per run.
Yes, any input MP4 can be upscaled, not just FLUX 3 output.
No, native audio sync is preserved through the upscale.
$1.43 per run at Precise (`creativity: 0`) and $2.00 per run at Creative (`creativity: 1`); pricing scales with input video duration.
From 1× to 4×, set via the `upscale_factor` parameter.
