ABOUT US
HFLUX is an AI video production platform that generates images, video, audio and shorts from 41 AI models. Screenplay and script writing, storyboarding, generation and editing all happen in one place. It runs in the browser, with nothing to install.
It is built and operated by H International.
What you can make
- Images — scene images, reference images, background removal, depth maps and pose extraction
- Video — text to video, image to video and first and end frames
- Shorts — vertical 9:16 video made with the Shorts · vertical preset on the node canvas or in the Video tab
- Dialogue video — in SCENE, turn sound on with Seedance 2.5 or a 2.0 model and characters speak their lines with matched lip movement
- Audio — speech synthesis, sound effects, background music and adding sound to a clip
- 3D scenes — a written shot becomes a 3D scene with characters, props and camera in place
- Editing — multitrack timeline, subtitle track, subtitles generated from speech, multilingual subtitle translation, silence trimming, colour correction, MP4 and FCP7 XML export
- Upscaling — 1080p, 2K and 4K
Which models it runs
10 image models, 18 video models and 13 audio models, 41 in total, in a single account. Take HFLUX RECAST out of the 18 video entries, since it reuses an existing clip rather than being a separate engine, and you have 17 video engines.
| Area | Models | Main engines |
|---|---|---|
| Image | 10 | Nano Banana 2 · Nano Banana Pro · GPT Image 2.5 · Seedream 5.0 · Grok Imagine |
| Video | 18 | Seedance 2.5 · Seedance 2.0 · Kling 3.0 · Veo 3.1 · MiniMax H3 · Wan 3.0 · Gemini Omni · Grok Imagine |
| Audio | 13 | Seed Audio 1.0 · SeedSpeech TTS 2.0 · Gemini 3.8 TTS · MiniMax Speech 2.8 · Kling SFX · Mureka · Lyria 3.5 |
The full list, model IDs included, is published at llms-full.txt.
Each family has its own page listing what you can actually select and what it deducts — Seedance · Kling · Veo and Gemini Omni · Seedream · GPT Image
Features with their own specification are written up separately — video upscaling · background removal · subtitles
How it differs from a single AI video generator
HFLUX is not one model behind a prompt box. It keeps models from several providers in one account and connects the work either side of generation in the same workspace. Three parts in particular are not found in most video generators.
- 3D STUDIO — turns a written shot into a 3D scene and exports GLB, USD or USDZ
- CANVAS node workspace — wires generation and editing steps together as a graph
- Remote MCP connector — calls HFLUX directly from a Claude or Codex chat window
3D STUDIO
Describe a shot in writing and 3D STUDIO builds a 3D scene with the characters, props, paths and camera placed for you. It runs inside the browser with no 3D software to install, and you can drag the on-screen handles afterwards to adjust position and angle yourself.
It draws on 184 poses and motions, 117 props and 29 environments. A finished scene exports as a reference video (mp4 at 1080p, 720p or 480p) to drive video generation, or as a 3D file (GLB, USD or USDZ) to open in Blender, Houdini, Unreal Engine or Nuke. The same 3D scene builder is also available as a 3D node inside the CANVAS node workspace.
MCP connector
HFLUX provides a remote MCP connector. Copy the server address from your account screen, register it in Claude or Codex, and you can request image and video generation from the chat window.
It follows the standard MCP specification and connections have been verified in Claude and Codex. Credits are deducted on the same basis as on the web.
How pricing works
HFLUX runs on prepaid credits rather than a monthly subscription. Nothing is charged on a fixed monthly cycle and credits are only deducted for what you actually generate, so a month without work costs nothing. Credits stay valid for one year from the date of payment and are not reset each month. A 100 credit welcome bonus is added on your first top-up.
Video is billed per second. Seedance 2.0 at 1080p costs 87 credits per second, so 15 seconds comes to 1,305 credits. Every model rate is published on the pricing page.
Languages
The interface is available in 9 languages: Korean, English, Japanese, German, Portuguese, Spanish, French, Simplified Chinese and Traditional Chinese. In the Edit tab, subtitles you make can be translated into these 9 languages.
Is there anything to install
No. Everything runs in the web browser, 3D STUDIO included, with no 3D software to install. Because 3D STUDIO is about orbiting a scene and adjusting it, it is built for a desktop-sized screen.
Who builds it
HFLUX is built and operated by H International. Payments outside Korea are processed through PayPal at fixed US dollar prices. You must be 18 or older to create an account.
