Process videos, audio, and media files with FFmpeg

Actions15

Overview

This node applies a fade transition effect to a video source using FFmpeg. It supports fading the video in or out, starting at a specified time and lasting for a defined duration. This is useful for creating smooth visual transitions in video editing workflows, such as gradually revealing or hiding a clip.

Practical examples:

  • Fade in a promotional video from black at the start.
  • Fade out an interview clip before transitioning to another scene.
  • Apply fade effects to highlight or soften video segments dynamically.

Properties

Name Meaning
Output Format The format of the output video file. Options: MP4, MOV, AVI, MKV
Video Source The input video to apply the fade effect on. Can be provided as a URL or binary data.
Fade Effect Type of fade effect to apply. Options: Fade In (gradually appear), Fade Out (gradually disappear)
Fade Start Time (seconds) The time in seconds when the fade effect should begin
Fade Duration (seconds) How long the fade effect lasts in seconds

Output

The node outputs a binary video file with the fade effect applied. The json output field is empty ({}), while the processed video is available in the binary property named data. This binary data contains the resulting video file encoded in the selected output format.

Dependencies

  • Requires FFmpeg installed and accessible in the environment where n8n runs.
  • No external API keys or services are needed.
  • Uses internal helper functions to handle temporary files and video processing.

Troubleshooting

  • Common issues:

    • Input video not found or inaccessible (invalid URL or missing binary data).
    • Unsupported video format or corrupted input file.
    • FFmpeg not installed or not in system PATH.
    • Fade start time or duration exceeding video length.

  • Error messages:

    • "No binary data found in property '...'": Check that the binary property name matches the input data.
    • "Font file not found at path: ..." (not relevant here but appears in code): Ensure correct file paths if fonts are used elsewhere.
    • "Operation "fade" on resource "transition" did not produce an output.": Indicates processing failure; verify input parameters and video validity.

  • Resolutions:

    • Verify input video source and format.
    • Confirm FFmpeg installation.
    • Adjust fade timing parameters within video duration.
    • Use continue-on-fail option to handle errors gracefully in workflows.
