What kind of transformations can Luma modify_video do?

Luma modify_video re-renders existing footage with prompt-driven changes — atmospheric shifts (fog, rain, golden hour), style transfers (cinematic, anime, noir), lighting overhauls, and environmental transformations. It preserves the original camera motion and spatial layout of the scene.

Does Luma generate audio or sound?

No. Luma Ray 3.2 only modifies the visual track of your source video. If the source has audio, Luma's output is video-only. Use a separate audio model like ElevenLabs or Suno through RunAPI to add sound after the visual transformation is complete.

Is Luma modify_video synchronous or asynchronous?

Asynchronous. The create endpoint returns a task_id immediately. Poll the task status endpoint or provide a callback_url to receive a webhook when the modified video is ready. Typical processing time is 30-120 seconds.

Can Hermes Agent chain Luma with video generation models in one workflow?

Yes. A Hermes Agent workflow can generate a video with Kling or Wan, then pass the output URL as source_video_url to Luma modify_video for atmospheric re-rendering — all through the same custom:runapi provider and RUNAPI_API_KEY. Each step uses the same async polling pattern.

Can Luma maintain character consistency when modifying video?

Luma preserves the original composition and spatial layout, including character positions and proportions. However, fine facial details can drift during heavy style transfers. For best character consistency, keep style changes moderate or use reference images to anchor key subjects.

Can Hermes Agent apply multiple Luma transformations in sequence?

Yes. Hermes Agent can chain Luma calls -- apply a style change first, then a scene modification, each building on the previous output. This enables complex multi-pass video editing within one workflow.

HERMES + LUMA

Hermes Agent で Luma を使う。

Luma Ray 3.2 は、空間的整合性と 3D シーン構造を保ったプロンプト駆動の変換で既存の動画を編集します。ソース動画の URL と変換を記述したテキストプロンプトを送ると、Luma が雰囲気のある照明、環境ディテール、物理的に一貫したカメラモーションで映像を再レンダリングします。Hermes Agent は RunAPI のカスタムエンドポイント経由でこれを呼び出します。

RunAPI を使って Luma Ray 3.2 で動画を編集します。

要件：
- RUNAPI_API_KEY から API キーを読み込みます。
- base_url を https://runapi.ai/v1 として custom:runapi プロバイダーを使用します。
- POST https://runapi.ai/api/v1/luma/modify_video を呼び出します。
- model を "luma-modify-video" に設定します。
- source_video_url を変換する動画の URL に設定します。
- prompt に希望する変換内容を記述します。
- このタスクは非同期です。返された task_id を status が "completed" になるまでポーリングします。
- 完了したら、レスポンスの output から編集済み動画の URL を読み取ります。

仕組み

Hermes Agent で Luma を使う3ステップ

Configure RunAPI

Set RUNAPI_API_KEY in the environment where Hermes Agent runs. If you already added RunAPI as a custom:runapi provider, the same key handles Luma video modification requests.

export RUNAPI_API_KEY=runapi_xxx

Call Luma modify_video

Send a POST request to the modify_video endpoint with model set to luma-modify-video, the source_video_url pointing to your input footage, and a prompt describing the transformation. Hermes Agent can build and send this request through the custom:runapi provider.

POST /api/v1/luma/modify_video

Poll for the result

The endpoint returns a task_id immediately. Poll the task status endpoint until the status is completed, then read the output video URL from the response. Video modification typically takes 30-120 seconds depending on complexity.

GET /api/v1/luma/modify_video/tsk_abc123
