ffmpeg Node

Overview

This node provides video transcoding functionality using ffmpeg. It allows users to convert input videos into different formats by specifying the desired video codec and various transcoding options such as bitrate, frame rate, and resolution. This is useful for scenarios where video files need to be optimized for different devices, platforms, or bandwidth constraints.

Practical examples include:

• Converting a raw video file into an MP4 format with H.264 codec for web streaming.
• Reducing video resolution and bitrate to create smaller files suitable for mobile viewing.
• Changing the frame rate of a video to match broadcast standards.

Properties

Output

The node outputs the transcoded video file in a binary field named according to the "Video Output Name" property. The json output contains metadata about the operation result, but the main content is the binary video data ready for further processing or saving.

Dependencies

• Requires an API key credential for accessing the underlying ffmpeg service.
• Relies on ffmpeg functionality exposed via an external API or service configured within n8n.
• No additional environment variables are explicitly required beyond the API authentication.

Troubleshooting

• Invalid Video Input: If the input video URL or binary field name is incorrect or inaccessible, the node will fail to retrieve the video. Ensure the input source is valid and accessible.
• Unsupported Codec: Specifying an unsupported video codec may cause errors. Verify that the codec is supported by the underlying ffmpeg service.
• Resource Limits: Large video files or high-resolution settings might exceed memory or processing limits. Consider reducing resolution or bitrate.
• Missing Credentials: The node requires a valid API key credential; missing or invalid credentials will prevent execution.
