ByteDance Seedance 2.0 Reference To Video (Official Edition)

The reference-to-video version of full Seedance 2.0 - the model that animates new video while respecting images, existing clips, even audio you feed it, running in the cloud through BizyAirPlus's Official Edition route. This is the highest-rung Seedance node in the pack, and it's aimed at one job: making video that stays faithful to what you already have.

Where T2V is a lottery and first-last-frame pins just two points, R2V gives the model a whole brief. Feed it a character sheet and it keeps the character. Feed it a product photo and it keeps the product. Feed it a reference clip and it echoes the motion. If you've been fighting consistency battles with local video models, this is the relief valve - and because it's the full model rather than Mini, the results hold up at 1080p.

How it works

Output node in the BizyAirPlus cloud layer. Flip BizyAirPlus ON in the action bar and the node forwards your references plus prompt to ByteDance's Seedance service, which renders the clip and returns it to your workflow. The reference sockets - images, videos, and audios - are all COMFY_AUTOGROW_V3 ports that accept lists, so you can feed several items of each type. This official node has the full reference set, audio included, which not every R2V node in the pack does.

The inputs that matter

• images / videos / audios - the references. Images carry subject and style, videos carry motion and pacing, audio can drive sync or mood. More isn't always better; a few coherent refs beat a pile of conflicting ones.
• prompt - the action. The references set the look; the prompt sets what happens.
• duration - COMBO, default 10 seconds.
• resolution - 1080p default.
• aspect_ratio - 16:9 default.
• seed - 0 to 2147483647.
• generate_audio - on by default.

There's no watermark or web-search toggle here - the official full model keeps the option surface tight, which is honestly fine.

The outputs

video for preview/save, urls for the direct link, request_id for support. Standard trio.

Installing it

Part of BizyAirPlus. 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, turn BizyAirPlus ON, key from bizyair.ai. Stored at ~/.BizyAirPlus/apikey.ini or BIZYAIR_API_KEY. The real machinery is the bizytrd and bizyair-cloudberry pip packages; nothing heavy, no model files.

Gotchas

Key missing or button OFF covers most first-run failures - read the ComfyUI console for the actual error. And the standing advice: keep your references consistent, or the model spends its quality budget negotiating between them. On billing, full R2V with multiple references is the premium end of the Seedance line, so iterate on the Mini nodes and save this one for shots that matter. If the Official route is down or pricier on your account, the Channel Edition node calls the same model.
