Vidu Q3 Text To Video (Channel Edition)

If you want to know what Vidu Q3 is about and spend as little time and money as possible finding out, this is the node. Turbo text-to-video on the Channel route: no image prep, no frills, and - unlike its Pro Channel sibling - it comes with a seed and audio on by default. Cheap speed, and the schema shows it.

What this node does

BizyTRD_Vidu_Q3_Turbo_Base_T2V_API turns a prompt into a clip on the Turbo tier via the lean Channel edition. It's the T2V entry point of the family, and it's worth comparing it to the Pro Channel T2V node, because the knob sets genuinely differ: this one runs at 720P default (Pro Channel T2V defaults to 540P), has a seed (Pro Channel T2V doesn't), and has audio on by default (Pro Channel T2V defaults to off). The variants aren't cut from one template - check the widget on your node before assuming.

Cloud execution like every BizyTRD node: flip BizyAirPlus ON, Turbo runs on BizyAir's servers, and ComfyUI streams back the result. No local inference.

The inputs that matter

• prompt - everything lives here; up to 5000 characters. Write motion, camera, mood.
• resolution - 720P default.
• duration - 1–16 seconds.
• aspect_ratio - 16:9 default.
• seed - 0 default, -1 = random. Lock it to reproduce a take.
• audio - on by default: Q3 generates dialogue and SFX.

Shared BizyAir options: api_config (endpoint/key override) and skip_error (placeholder instead of abort).

Outputs

• video - the finished clip, wired into preview or save.
• request_id - cloud task ID.
• urls - hosted result URLs.

How to install

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

Restart ComfyUI (or install "BizyAirPlus" via ComfyUI Manager). Deps: bizyair-cloudberry and bizytrd; no model files. First run: account at bizyair.ai → API key → enter when the ON button prompts (or Settings > BizyAirPlus > API Key; key at ~/.BizyAirPlus/apikey.ini).

Where people get burned

The same trade as every Turbo node: you're trading fine-detail fidelity for speed and cost. For a first-pass idea this is the right tool; for a hero shot you'll want Pro. And since there's no style knob here (unlike some of the other Vidu nodes), you steer the look entirely through the prompt - be specific about lighting and atmosphere.

Pack note, one last time: BizyAir's malware reputation is leftover from a 2025 ComfyUI Manager auto-install bug - it's a legitimate SiliconFlow pack. If you ever remove it, pip uninstall bizyair-cloudberry bizytrd beats deleting the folder, which leaves packages behind.
