Vidu Q3 Pro Text To Video (Official Edition)

This node has a feature no other Vidu node in the pack has: a discount button. Vidu Q3 Pro's Official T2V node is the full-fidelity text-to-video route with seed control, synchronized audio, and an off_peak mode that trades speed for a lower point cost. If you generate a lot of clips, this is worth knowing about.

What this node does

BizyTRD_Vidu_Q3_Pro_Official_T2V_API turns a prompt into a Q3 Pro clip - up to 16 seconds, 720P by default, audio on. It's the most complete T2V member of the family: the Channel edition strips this down, while the Official edition gives you seed control and the off-peak option.

Cloud execution like every BizyTRD node: flip BizyAirPlus ON, and Q3 Pro runs on BizyAir's servers while ComfyUI streams back the result.

The inputs that matter

• prompt - your whole job, up to 5000 characters.
• 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 sound effects. (Note the difference from the Channel T2V node, which defaults to off.)
• off_peak - the one worth reading: "Enable trough mode to consume lower points, complete within 48 hours, timeout automatically cancels and refunds." So: cheaper, but your clip lands whenever the farm gets to it, up to two days later. Perfect for batch background work, wrong for "I need this now."

Plus the shared api_config (endpoint/key override) and skip_error (placeholder instead of abort).

Outputs

• video - the finished clip, ready for preview/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 obvious one: enabling off_peak and then refreshing for your result like it's a normal queue. It can take up to 48 hours - that's the deal. Also remember T2V has the weakest subject consistency in the family; if faces drift across the clip, anchor them with the I2V or FLF nodes instead of rewriting the prompt forever.

Pack note, as always: BizyAir's malware reputation is leftover from a 2025 ComfyUI Manager auto-install bug - legitimate SiliconFlow pack, and it's removed properly with pip uninstall bizyair-cloudberry bizytrd, not by deleting the folder.
