Skywork AI Skyreels V3 Reference To Video (Official Edition)

Reference-to-video is Skywork's signature trick, and it's the answer to the oldest complaint in AI video: "great clip, wrong person." Skyreels V3's R2V node takes reference images of a subject - a face, a character sheet, an object you don't want drifting - and generates a clip where that subject stays recognizably itself.

What this node does

BizyTRD_Skyreels_V3_Official_R2V_API is the V3 Reference To Video node in BizyAirPlus. Instead of trusting the prompt to hold a face together across 80 frames, you hand it one or more ref_images and it conditions the whole generation on them. This is the same family of trick that Kling and the Vidu reference modes use: the model knows who it's animating because you showed it.

It's a cloud node, so none of this runs on your machine. Flip the BizyAirPlus button ON, and the node uploads your reference images to BizyAir's servers, the V3 model does its thing, and the finished clip streams back into ComfyUI. Your GPU sits this one out.

The inputs that matter

• ref_images - the reference images. It's an autogrowing list, so you can drop in several angles of the same subject. More views, more stability.
• prompt - what's happening in the clip ("the character looks at the camera and smiles").
• duration - and here's the catch: 1 to 5 seconds. V3 R2V is a short-clip node. This is for shots, not scenes - a beat of motion, an expression, a product turn. If you need ten seconds, that's V4's territory.
• aspect_ratio - 16:9 by default, change it to match where the clip will land.

Shared BizyAir extras: api_config overrides base URL/key for one request, skip_error swaps a failed cloud call for an error placeholder instead of killing the workflow. Both are worth leaving alone until you need them.

Outputs

• video - the generated clip, ready for a preview or save node.
• request_id - the cloud task ID for logs and support.
• urls - the 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). Dependencies are bizyair-cloudberry and bizytrd - no models download because nothing runs locally. First time: sign up at bizyair.ai, get an API key, enter it when the ON button prompts (or Settings > BizyAirPlus > API Key; stored at ~/.BizyAirPlus/apikey.ini).

Where people get burned

The 5-second ceiling trips everyone once. People treat this like a general video generator, feed it a long action prompt, and get confused why the tooltip screams at them. It's a beat generator - plan shots, not scenes, and you'll be happy.

And the pack reputation thing, because it comes up a lot: ComfyUI Manager briefly auto-installed BizyAir for unrelated workflows in mid-2025, so a lot of Reddit threads call it malware. It's a legitimate SiliconFlow pack. If you installed it by accident, uninstall properly (pip uninstall bizyair-cloudberry bizytrd) rather than just deleting the folder, which leaves the packages in your venv.
