wan / v2.6 / fal / image-to-video

Wan 2.6 is Alibaba's December 2025 closed release - the one where the community stopped pretending the open era was coming back - and this node runs it image-to-video on fal's fleet through Civitai's cloud. First frame in, native VIDEO out, billed in Buzz. It's part of the official civitai-comfy-nodes pack.

You should know the reception going in: the community's read on 2.6 was harsh - "looked like straight dog shit" was a genuinely upvoted take, and by the time 2.7 arrived nobody expected much. That's the counterweight to this node's two genuinely new features: multi-shot (a single run producing multiple shots) and background music via an audio URL. If those matter to you, 2.6 is the only Wan node in the pack with them.

The inputs that matter

prompt and cfg_scale (default 4) are required. Then:

• source_image / images - your starting frame.
• resolution - 720p or 1080p (default 1080p).
• multi_shots - off by default. When on, the run produces multiple shots rather than a single continuous clip. This is the 2.6 headline feature; budget for it - more output means more Buzz.
• audio_url - a URL to an audio file (3–30 seconds, up to 15 MB) used as background music. The tooltip notes it's supported for text-to-video and image-to-video only - so this is the right node for it; the reference-to-video variant can't take audio.
• enable_prompt_expansion - on by default; fal's prompt rewrite. Off for exact prompts.
• negative_prompt - steering.
• enable_safety_checker - off by default; fal's safety pass.
• loras - CIVITAI_LORAS socket; trigger words go in prompt.
• duration 1–30s (default 5), frame_rate 24, steps 10–50, seed, api_config.

Outputs

Standard trio: video (VIDEO) into a Save Video / preview node, workflow_id (STRING) for the Civitai sidebar, raw_json (STRING) for response and cost.

Install and auth

One-time, pack-wide. ComfyUI Manager → search Civitai Comfy Nodes → install, restart:

cd ComfyUI/custom_nodes
git clone https://github.com/civitai/civitai-comfy-nodes.git
pip install -r civitai-comfy-nodes/requirements.txt   # just `requests`

Auth: Civitai Auth node, CIVITAI_API_TOKEN (headless), or sidebar sign-in.

Troubleshooting and takes

• Set expectations. 2.6 is a closed model that underwhelmed at launch. Its case is the features - multi-shots and audio - not raw quality leadership.
• Audio URL must be reachable. The audio_url is fetched by fal's pipeline, so a localhost or private URL will fail. Use a publicly-accessible file.
• Multi-shot multiplies cost. One toggle, bigger meter, longer queue. Start with it off, run a keeper, then decide.
• Closed model, fixed filter. Alibaba's moderation applies server-side; no local patch. Refusals are the model.
• Slow / timeout. Pack launched June 2026 during Civitai's GPU crunch; 1080p + multi-shot is the timeout recipe. Default timeout 30 min - raise via Civitai Auth timeout_minutes or CIVITAI_COMFY_TIMEOUT.
• Early preview. Generated nodes "may change without notice."

Reach for this when you specifically want Wan 2.6's multi-shot or background-music capability on a first frame. For plain quality at a lower meter, the open Wan 2.2 fal nodes are the community's default.
