Overview
The node provides a variety of utility functions grouped under different resources and operations. Specifically, for the Operator resource with the Thumbnail operation, it generates a thumbnail image from a given video URL. This is useful in scenarios where you want to extract a preview image from a video for display purposes, such as creating video galleries, previews in content management systems, or generating thumbnails for social media posts.
For example, you can input a video URL and get back a thumbnail image either as a downloadable file or as a URL pointing to the generated thumbnail.
Properties
| Name | Meaning |
|---|---|
| Video URL | The URL of the video from which the thumbnail will be generated. |
| Get File as URL | Boolean option to specify whether the thumbnail should be returned as a URL (true) or as a file (false). |
| File Name | The desired name for the output thumbnail file. If you want to keep the file extension, include it here. |
| Code Variables | A collection of code variables (name/value pairs) that can be used if the user wants to pass additional dynamic data related to code execution. This is more relevant when running code-related operations but is available as an input property. |
Output
The node outputs JSON data representing the result of the thumbnail generation operation. The exact structure depends on whether the thumbnail is returned as a URL or as a file:
- If Get File as URL is true, the output JSON contains a URL string pointing to the generated thumbnail image.
- If false, the output includes the binary data of the thumbnail image file, which can be used downstream in workflows that handle files.
The output JSON typically includes metadata about the thumbnail and the actual image data or URL.
Dependencies
- Requires an API key credential for authentication with the external service providing the utilities.
- The node internally calls an external API endpoint corresponding to the resource and operation (e.g.,
operator/thumbnail). - No other explicit dependencies are required.
Troubleshooting
- Invalid Video URL: If the provided video URL is invalid or inaccessible, the node may throw an error or fail to generate a thumbnail. Ensure the URL is correct and publicly accessible.
- File Name Issues: Omitting the file extension in the File Name property might cause issues with downstream nodes expecting a specific file type. Always include the appropriate extension (e.g.,
.jpg,.png) if you want to preserve the file format. - API Authentication Errors: Missing or incorrect API credentials will prevent the node from functioning. Verify that the API key credential is correctly configured.
- Network Issues: Connectivity problems to the external API service can cause timeouts or failures. Check network access and retry.
- Continue On Fail: If enabled, the node will continue processing subsequent items even if one fails, returning error details in the output JSON.
