ffmpeg NodeInstall

Overview

This node provides various ffmpeg-related functionalities, including video processing tasks. Specifically, the "Combine Images" operation under the "Video Processing" resource allows users to create a video by combining multiple images sequentially. Each image is displayed for a specified duration, effectively generating a slideshow or time-lapse video from a list of image URLs.

Common scenarios where this node is beneficial include:

• Creating promotional videos or slideshows from a set of product images.
• Generating time-lapse videos from a series of photos.
• Automating video content creation from static images for social media or presentations.

For example, a user can input a list of image URLs and specify that each image should be shown for 2 seconds, resulting in a video where each image appears for 2 seconds before transitioning to the next.

Properties

Output

The node outputs JSON data representing the result of the video processing operation. This typically includes metadata about the generated video file such as its location or URL. If binary data output is supported, it would contain the actual video file data encoded in a binary field, allowing downstream nodes to use or save the video.

Dependencies

• Requires an API key credential for accessing the underlying ffmpeg service or API.
• Relies on external ffmpeg functionality exposed via an API endpoint configured in n8n credentials.
• The node expects valid internet access to fetch images from provided URLs.

Troubleshooting

• Invalid Image URLs: If any image URL is invalid or inaccessible, the operation may fail or produce incomplete videos. Ensure all URLs are reachable and point to valid image files.
• Incorrect Duration Format: The "Images Duration" property must be a valid number (as a string). Non-numeric or zero values may cause errors or unexpected behavior.
• API Authentication Errors: Missing or incorrect API credentials will prevent the node from executing successfully. Verify that the API key credential is correctly configured.
• Timeouts or Network Issues: Since the node fetches images from URLs, network problems can cause failures. Check connectivity and URL accessibility.
• Unsupported Image Formats: The underlying ffmpeg service might not support certain image formats. Use common formats like JPEG or PNG.
