Practical overview
When it fits
Use it when a Python project needs to submit video-generation jobs to FLUX 3 through MuAPI, particularly for text prompts, image animation or synchronized audio.
Who it is for
- Python developers adding cloud video generation to an application or workflow.
- Teams building prompt-based video generation that can use text or a source image.
- Developers connecting video-generation tools to compatible AI clients through the documented MCP server.
Documented uses
- Request a video clip from a text prompt.
- Animate a static image into a video.
- Request synchronized audio alongside generated video.
- Continue a video with prompt-guided motion or generate a transition between keyframes.
- Use the documented draft or upscaling endpoints in a video workflow.
Requirements & limits
The repository is public and lists an MIT license. Its documentation requires a MuAPI API key for service use.
- Python is the documented wrapper language, with the repository listing Python 3.7+.
- The generation service is external and cloud-based, so local execution is not the documented operating mode.
- The sample workflow is asynchronous: it submits a job, waits using its request ID and then reads the result URL.
- The README describes text-to-video, image-to-video, keyframe transitions, video extension, draft modes and upscaling.
- The repository lists MIT licensing.
Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.
Set up the Python wrapper
Install the wrapper and configure the MuAPI credential needed for its cloud video-generation service.
Before you start
- Python 3.7 or later, as listed by the repository
- A MuAPI API key
Steps
Install the package with pip install flux-3-video-api.
Create a .env file in the repository root.
Add MUAPI_API_KEY=your_muapi_api_key_here to the .env file.
Expected outcome
The Python wrapper is installed and the documented credential variable is configured for API use.
Guide limitations
- This setup does not run video generation locally; requests use the cloud API.
- The guide documents setup, not confirmation that a request succeeds.
Submit a text-to-video request with synchronized audio
Use the documented Python example to request a 720p, five-second video from a text prompt with audio generation enabled.
Before you start
- The wrapper installed and MUAPI_API_KEY configured
- Python
Steps
Import Flux3VideoAPI from flux3_video_api and initialize the client.
Call text_to_video with a prompt, aspect_ratio="16:9", resolution="720p", duration=5, and generate_audio=True.
Pass the returned request_id to wait_for_completion.
Read the video URL from the completed result's outputs, or its url value.
Expected outcome
The documented workflow returns a completed result containing a video URL, if the cloud request completes successfully.
Guide limitations
- Generation depends on the external MuAPI service and a valid API key.
- The example is documentation, not a verified execution test.
