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 in scenarios where you need to prepare videos for different platforms or devices, optimize file size, or change encoding parameters.

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 mobile-friendly versions.
• Changing frame rates to match broadcast standards.

Properties

Output

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

Dependencies

• Requires an API key credential for accessing the underlying ffmpeg service.
• Depends on an external ffmpeg processing backend accessible via the configured API.
• No additional environment variables are explicitly required beyond the API authentication.

Troubleshooting

• Invalid video input: Ensure the input video URL is accessible or the binary input field name is correct.
• Unsupported codec: Verify that the specified video codec is supported by the backend ffmpeg service.
• Incorrect transcoding options: Check that bitrate, frame rate, and resolution values are within acceptable ranges.
• API authentication errors: Confirm that the API key credential is correctly configured and has necessary permissions.
• Timeouts or processing failures: Large videos or complex transcoding settings may require longer processing times; consider adjusting timeouts or simplifying options.
