emaki-haystack

Haystack components for emaki (emaki.ai), the Japanese-language AI video generator for Seedance 2.5 and Seedance 2.0. Render Seedance 2.5 clips, image to video and AI images inside a pipeline on one emaki API key.

pip install emaki-haystack
export EMAKI_API_KEY=sk-...   # create one at https://emaki.ai/settings/apikeys

from emaki_haystack import EmakiImageGenerator, EmakiVideoGenerator

EmakiVideoGenerator(duration=5).run(prompt="a lighthouse beam sweeping across fog at night, slow push-in")
# {"videos": ["https://cdn.emaki.ai/..."]}

EmakiImageGenerator(aspect_ratio="16:9").run(prompt="a lighthouse in fog, long exposure")
# {"images": ["https://cdn.emaki.ai/..."]}

In a pipeline

Write the shot with an LLM, render it with Seedance 2.5:

from haystack import Pipeline
from haystack.components.builders import PromptBuilder
from haystack.components.generators import OpenAIGenerator
from emaki_haystack import EmakiVideoGenerator

p = Pipeline()
p.add_component("brief", PromptBuilder("Write one video prompt for a 5-second product teaser about {{topic}}. Name the action and the camera move."))
p.add_component("llm", OpenAIGenerator())
p.add_component("render", EmakiVideoGenerator(duration=5, aspect_ratio="9:16"))
p.connect("brief", "llm")
p.connect("llm.replies", "render.prompt")

(llm.replies is a list; add a small adapter component that takes replies[0] if your Haystack version does not convert it.)

Components

EmakiVideoGenerator takes model, duration, resolution, aspect_ratio and generate_audio at init. It defaults to seedance_2_5; seedance_2 (Seedance 2.0), seedance_2_fast, seedance_2_mini, minimax_h3 and veo_3_1 are the other ids. EmakiImageGenerator defaults to nano_banana_2_lite. Both serialize with to_dict / from_dict; the key is a Haystack Secret read from EMAKI_API_KEY.

Each run costs credits on your emaki account, the same price as on the website. Errors raise the emaki client's exceptions (AuthError, QuotaError, PlanError, BusyError, RejectedError, GenerationFailed) so a pipeline can branch on them. Finished clips can be sharpened with the AI video upscaler.
