Vidu Q3 Turbo Image To Video (Official Edition)

The Channel Turbo I2V node is the bare iteration machine; this is its smarter sibling. Vidu Q3 Turbo I2V in the Official edition keeps the fast, cheap tier but adds what iteration actually needs - a seed you can lock, an optional end frame, and a prompt that's optional because the model is fine animating a still on its own.

What this node does

BizyTRD_Vidu_Q3_Turbo_Official_I2V_API animates an image forward on the Turbo tier with the full Official knob set. The input image's aspect ratio should sit between 1:4 and 4:1 per the tooltip. Cloud execution, as always: flip BizyAirPlus ON, and Turbo runs on BizyAir's servers while ComfyUI streams back the clip.

The inputs that matter

• image - the first frame, required.
• prompt - optional here. Leave it empty and the model animates the still on its own interpretation; fill it to steer motion.
• last_frame_image - optional; provide it and this I2V node quietly becomes first-last-frame generation. No node swap needed.
• resolution - 720P default.
• duration - 1–16 seconds.
• audio - on by default: Q3 syncs dialogue and SFX.
• seed - 0 default, -1 = random. This is the reason to pick Official over Channel on the Turbo tier: seed-locked, reproducible takes while still paying Turbo prices.
• aspect_ratio - 16:9 default.
• is_rec - recommendation prompt at an extra 10 credits per task; leave off unless you want auto-prompting.

Shared BizyAir options: api_config and skip_error.

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; key at ~/.BizyAirPlus/apikey.ini).

Where people get burned

Same seed semantics as every official Vidu node: 0 is a fixed seed, -1 is random - if your takes look suspiciously similar, that's not a bug. And remember the optional prompt means the model fills in its own interpretation when you leave it blank; if the motion comes out generic, that's why. For fine expression work - the subtle eye and mouth movement Q3 is known for - Turbo trades some of that away, so keep Pro in mind for hero takes.

Pack note: BizyAir's malware reputation is leftover from a 2025 ComfyUI Manager auto-install bug - legitimate SiliconFlow pack; remove it with pip uninstall bizyair-cloudberry bizytrd if needed.
