Alibaba Happyhorse 1.0 Text To Video (Official Edition)

Alibaba HappyHorse 1.0, text-to-video, official edition. A prompt in, a video out, with the controls you actually want: 720P or 1080P, a 3–15 second duration slider, a ratio picker, and a proper seed input. Of all the T2V nodes in this pack, this one gives you the most conventional local-workflow feel - it behaves like a sampler you'd run yourself, just hosted.

For a beginner, the seed control is the feature that makes it feel like ComfyUI instead of a random video lottery. The seed input defaults to 0 with -1 meaning "auto," so when you get a clip you love you can pin the seed, tweak the prompt, and see exactly how the change moved the result. That kind of iteration is how you learn to write for the model at all.

How it works

BizyTRD cloud wrapper. prompt (required) goes to the API with resolution (default 1080P), ratio (default 16:9), duration (3–15s integer, default 5 in the schema), seed, and watermark (default on), and a VIDEO comes back. watermark defaults to on - that's the official commercial API telling you its terms are attached, so leave it unless you're covered. api_config overrides the endpoint and key per request; skip_error outputs a placeholder instead of aborting the workflow.

Inputs and outputs

• prompt (required, multiline).
• Optional: resolution, ratio, duration, seed, watermark, api_config, skip_error.
• Outputs: video (VIDEO), request_id, urls.

Installing BizyAirPlus

ComfyUI Manager: "BizyAirPlus", or:

cd /path/to/ComfyUI/custom_nodes
git clone https://github.com/siliconflow/BizyAirPlus.git
cd BizyAirPlus
python -m pip install -r requirements.txt

Restart, account at bizyair.ai, API key, BizyAirPlus button ON. Dependencies: bizyair-cloudberry, bizytrd.

Common issues

Two things bite people. First, the seed tooltip is explicit that -1 means system-autogenerated - if your clips aren't reproducible, check you didn't leave it at -1. Second, the watermark: it's on by default and easy to miss until you've generated a batch and notice the logo. Then the pack standard - missing button means the wrong dependency environment (pip show bizyair-cloudberry), cloud failures are key/network/console, and it's metered. HappyHorse's honest positioning is value-for-money over absolute top-tier quality, so it's a reasonable default to reach for while you're learning.
