Force Trim - Fixed Length Video

If you configured the trim tool to restrict the duration of the video by setting a minimum and/or maximum duration you can define the startup behavior of the video editor as follows:

`forceMode`#

The configuration.trim.forceMode option determines how the video editor behaves. For this, three options are provided:

ALWAYS

In this mode, the composition or trim tool will always automatically be presented after opening for the user to review and adjust the length of the video.

IF_NEEDED

In this mode, the editor will only present

the composition tool, if your initial composition is longer than maximumDuration or shorter than minimumDuration, or
the trim tool, if your initial video is longer than maximumDuration.

SILENT

In this mode, the editor will automatically trim the video to the maximumDuration without opening any tool.


import {
  Configuration,
  ForceTrimMode,
  VESDK,
} from "react-native-videoeditorsdk";

export const videoEnforceDurationExample = async (): Promise<void> => {
  // Add a video from the assets directory.
  const video = require("../../../../assets/vesdk/Skater.mp4");

  // Create a `Configuration` object.
  const configuration: Configuration = {
    // The duration limits of these configuration options are
    // also respected by the composition tool.
    trim: {
      // By default the editor does not have a maximum duration.
      // For this example the duration is set, e.g. for a social
      // media application where the posts are not allowed to be
      // longer than 5 seconds.
      maximumDuration: 5.0,

      // By default the editor does not limit the maximum video duration.
      // For this example the duration is set, e.g. for a social
      // media application where the posts are not allowed to be
      // shorter than 2 seconds.
      minimumDuration: 2.0,

      // By default the editor trims the video automatically if it is
      // longer than the specified maximum duration. For this example the user
      // is prompted to review and adjust the automatically trimmed video.
      forceMode: ForceTrimMode.IF_NEEDED,
    },
  };
  try {
    // Open the video editor and handle the export as well as any occuring errors.
    const result = await VESDK.openEditor(video, configuration);

    if (result != null) {
      // The user exported a new video successfully and the newly generated video is located at `result.video`.
      console.log(result?.video);
    } else {
      // The user tapped on the cancel button within the editor.
      return;
    }
  } catch (error) {
    // There was an error generating the video.
    console.log(error);
  }
};
