Overview

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.

1Post-Production: Deliver a FLUX 3 Video generation at a higher final resolution.
2Archive Restoration: Sharpen and upscale lower-resolution existing footage.
3Social Media: Prepare video for platforms that expect higher-resolution uploads.
4Broadcast Prep: Upscale AI-generated b-roll for broadcast-quality delivery.
5Detail Recovery: Use the creative tier to reconstruct fine detail lost in compression.

How to Use FLUX 3 Video Upscaler

  1. Provide a source video via video_url — any MP4, including FLUX 3 Video output.

  2. Optionally add a prompt describing the desired enhancement direction, detail style, or visual refinement.

  3. Set upscale_factor (1–4×) to control how much larger the output becomes.

  4. Choose creativity — 0 (Precise) stays closer to the source, 1 (Creative) reconstructs more detail at a higher price.

  5. Submit the request:

curl -X POST https://api.muapi.ai/api/v1/flux-3-video-upscaler \
  -H "x-api-key: YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"video_url": "https://example.com/clip.mp4", "upscale_factor": 2, "creativity": 0}'
  1. Poll /api/v1/predictions/{request_id}/result until completed.

Common Questions

Frequently asked

What is FLUX 3 Video Upscaler?

It raises any video's resolution beyond its native output, preserving motion coherence and native audio sync while sharpening detail.

What's the difference between Precise and Creative?

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.

Does it work on videos not generated by FLUX 3?

Yes, any input MP4 can be upscaled, not just FLUX 3 output.

Does upscaling affect the audio track?

No, native audio sync is preserved through the upscale.

How much does FLUX 3 Video Upscaler cost?

$1.43 per run at Precise (`creativity: 0`) and $2.00 per run at Creative (`creativity: 1`); pricing scales with input video duration.

What upscale factors are supported?

From 1× to 4×, set via the `upscale_factor` parameter.
