getSilentParts()v4.0.18

Gets the silent parts of a video or audio in Node.js. Useful for cutting out silence from a video.

Example​

silent-parts.mjs
import {getSilentParts} from '@remotion/renderer';

const {silentParts, durationInSeconds} = await getSilentParts({
  src: '/Users/john/Documents/bunny.mp4',
  noiseThresholdInDecibels: -20,
  minDurationInSeconds: 1,
});

console.log(silentParts); // [{startInSeconds: 0, endInSeconds: 1.5}]
info

Pass an absolute path to getSilentParts(). URLs are not supported.

Arguments​

An object which takes the following properties:

source​

string

A local video or audio file path.

noiseThresholdInDecibels?​

number

The threshold in decibels. If the audio is below this threshold, it is considered silent. The default is -20. Must be less than 30.

minDurationInSeconds?​

number

The minimum duration of a silent part in seconds. The default is 1.

logLevel?​

One of trace, verbose, info, warn, error.
Determines how much info is being logged to the console.

Default info.

binariesDirectory?v4.0.120​

The directory where the platform-specific binaries and libraries that Remotion needs are located. Those include an ffmpeg and ffprobe binary, a Rust binary for various tasks, and various shared libraries. If the value is set to null, which is the default, then the path of a platform-specific package located at node_modules/@remotion/compositor-* is selected.
This option is useful in environments where Remotion is not officially supported to run like bundled serverless functions or Electron.

Return Value​

The return value is an object with the following properties:

silentParts​

An array of objects with the following properties:

  • startInSeconds: The start time of the silent part in seconds.
  • endInSeconds: The end time of the silent part in seconds.

audibleParts​

The inverse of the silentParts array.
An array of objects with the following properties:

  • startInSeconds: The start time of the audible part in seconds.
  • endInSeconds: The end time of the audible part in seconds.

durationInSeconds​

The time length of the media in seconds.
