ByteDance Seedance 2.0 Mini Reference To Video (Official Edition)

Reference-to-video is how you keep a character, a product, or a style consistent across generations - you feed the model examples and it respects them. This node runs ByteDance's Seedance 2.0 Mini R2V through the Official Edition route (the vendor's direct API, served by BizyAirPlus), and it accepts both images and existing videos as references.

If your only experience of text-to-video is re-rolling a face twenty times, this is the node that changes your process. Instead of hoping the model remembers what your character looked like three prompts ago, you pin it with a reference image. The Mini tier keeps it fast and cheap while you iterate; full Seedance 2.0 is there if you need to polish the final pass.

How it works

Flip BizyAirPlus ON in the action bar and this output node forwards your references and prompt to Seedance's cloud service, then returns the finished video to the workflow. The reference inputs - images and videos - are COMFY_AUTOGROW_V3 ports, which accept lists, so you can feed several images for a blend or a short clip as a motion reference. Note this official Mini node drops the separate audio reference socket that the Channel Mini R2V has; here it's images and video only.

The inputs that matter

• images - the primary reference. A single character or style image goes a long way.
• videos - optional motion/style reference; useful for camera movement or pacing you want echoed.
• prompt - the action you want, on top of whatever the references establish.
• duration - 4 to 15 seconds (default 10).
• resolution - 480p default.
• aspect_ratio, seed, generate_audio - the standard set; generate_audio on by default.

COMFY_AUTOGROW_V3 sockets accept a single item or a whole list without any workflow restructuring, which is a quiet quality-of-life win: pipe one image in, or drag a selection, and the node just handles it.

The outputs

video for preview or saving, urls for the direct link, request_id for support traceability. The same trio every BizyTRD node returns.

Installing it

Ships in BizyAirPlus. ComfyUI Manager → search "BizyAirPlus", or:

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

Restart, toggle BizyAirPlus ON, and enter your key from bizyair.ai. It's stored at ~/.BizyAirPlus/apikey.ini or as BIZYAIR_API_KEY. Dependencies are the lightweight bizyair-cloudberry and bizytrd pip packages - no models to download, no GPU requirements.

Gotchas

The usual trio of cloud-node failures applies: button OFF, key missing, or network down, and the ComfyUI console has the specifics. And yes, if you've seen people calling BizyAir suspicious, that was the old Manager auto-install confusion - legit SiliconFlow product, since fixed. R2V-specific advice: references that disagree with each other force compromises, so feed it consistent material. And don't expect the Mini tier to preserve identity perfectly on rapid motion; for locked-in character work you may want to up the reference count rather than the prompt.
