Vidu splits its Q3 line into Pro and Turbo, and the whole pitch for Turbo is in the name: faster, cheaper, slightly less polish. If you're iterating on first-last-frame shots and the Pro tier's queue times or points are eating you alive, this Channel edition of Turbo FLF is the speed run.
What this node does
BizyTRD_Vidu_Q3_Turbo_Base_FLF2V_API animates between a first_frame_image and a last_frame_image, same job as the Pro FLF nodes - match cuts, locked endings, storyboard in-betweens - but on the Turbo tier and in the lean Channel edition. That means no seed control, no recommendation-prompt upsell, no off-peak mode. Just the shot, fast.
Cloud execution, like every BizyTRD node: flip BizyAirPlus ON, Turbo runs on BizyAir's servers, and ComfyUI uploads your frames and streams back the clip. Nothing runs on your GPU.
The inputs that matter
first_frame_image/last_frame_image- the two bookends, both required.prompt- 1–4000 characters of motion between them.resolution- 720P default.duration- combo, 1–16 seconds (the tooltip even says "q3-pro available range" - the two tiers share the envelope).style-generaldefault.movement_amplitude-autodefault; adjust how much motion the model applies.audio- on by default: Q3 syncs dialogue and SFX. Flip off for silent.
Shared BizyAir options: api_config (endpoint/key override) and skip_error (placeholder instead of abort).
Outputs
video- the finished clip; wire 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
Turbo is a trade, and the trade shows most in FLF shots: the in-between motion can come out stiffer than Pro, especially on complex transitions. If your bookended shot needs a smooth physical bridge, Pro is the safer call. Also keep the two anchor frames visually related - mismatched bookends make any model invent an ugly bridge, and Turbo has less budget to paper over it.
And the pack note that keeps coming up: 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, not by deleting the folder alone.
