Luma: AI video generator

[Admin]

Luma AI is a tool that lets you create videos from simple text prompts or photos. Just describe what you want, set a few options, and Luma AI generates it for you.

1. Credentials:

• Luma node has no need for credentials, however you have an option to use your unique key or token to access Luma AI’s tools and services.

2. Operation Type:

• Generation: This tells Luma AI to create a new video based on your instructions.

• get_generation: This means retrieving or getting a previously created video from Luma AI.

3. Prompt:

• This is where you give specific instructions for what you want Luma AI to create. Think of it as describing the image, object, or scene you want.

4. Aspect Ratio:

• The aspect ratio controls the shape of the output. For example, an aspect ratio of 16:9 gives a wider view, while 1:1 makes a square image. You set this depending on your needs.

5. Loop:

• If you want the generated content to repeat or loop (like an animation or a 3D scene that cycles smoothly), you can set this option.

6. Keyframes:

Keyframes help control changes over time in animations or 3D sequences.

• Type:

  • Image: Use a specific image as a keyframe, meaning Luma AI will use that image at a certain point in the animation.
  • Generation: Use a previously generated output as a keyframe to guide changes in the animation.

• URL: This is the link to the image or generation you want to use as a keyframe.

How to use on Scade

Generating a video from a prompt:

1. Create a Text Input: In the Start node, add a text input field for the prompt and connect it to the prompt field of the Luma node.
   

   
   
   
   

2. Final Output: Add a file input field in the end node to save the final output.

   

3. Start the flow by pressing “Start Flow” button and enjoy the result.

   
   
   
   

Generating a video from image and extend video length. (Advanced)

1. Create a Text Input: In the Start node, add a text input field for the prompt and connect it to the prompt field of the Luma node.

2. Adding Motion to an Image: To animate an image, create a file input in the Start node.
   

   
   
   Upload your image.
   In the Luma node, add a keyframe with the type set to image. Press an eye icon to show it on the node.
   
   
   
   
   

   Add the file input field in the end node and start the flow.

3. Extending Video Length: To extend the video, add another Luma node, chose get_generation as operation type. In the Generation ID field chose input type as expression and drag {success}{id} from the left menu to the right.
   

   

   Add a keyframe and change type to generation. For ID field choose expression and drag {success}{id} from the left menu to the right.
   

   

Add add another Luma node, chose generation as operation type, for a prompt change input type to expression and add {success}{prompt} from Start Node. Add a keyframe and change type to generation. For ID field choose expression and drag {success}{id} from the left menu to the right. Now you will have 9-10 seconds video as a result.

6. Final Output: Add a file input field in the end node to save the final output.
