What is the Video Editor Solution?

The Video Editor is a prebuilt solution powered by the CreativeEditor SDK (CE.SDK) that enables fast integration of high-performance video editing into web, mobile, and desktop applications. It’s designed to help your users create professional-grade videos—from short social clips to long-form stories—directly within your app.

Skip building a video editor from scratch. This fully client-side solution provides a solid foundation with an extensible UI and a robust engine API to power video editing in any use case.

Understanding CE.SDK Architecture & API

The sections below provide an overview of the key components of the CE.SDK video editor UI and its API architecture.

CreativeEditor Video UI

The CE.SDK video UI is designed for intuitive video creation and editing. Below are the main components and customizable elements within the UI:

• Canvas: The main interaction area for video content.
• Dock: Entry point for interactions not directly related to the selected video block, often used for accessing asset libraries.
• Canvas Menu: Access block-specific settings such as duplication or deletion.
• Inspector Bar: Manage block-specific functionalities, like adjusting properties of the selected block.
• Navigation Bar: Handles global scene actions like undo/redo and zoom.
• Canvas Bar: Provides tools for managing the overall canvas, such as adding pages or controlling zoom.
• Timeline: The core video editing control, where clips and audio are arranged over time.

CreativeEngine

CreativeEngine is the core of CE.SDK, responsible for managing the rendering and manipulation of video scenes. It can be used in headless mode or integrated with the CreativeEditor UI. Below are key features and APIs provided by the CreativeEngine:

• Scene Management: Programmatically create, load, save, and modify video scenes.
• Block Manipulation: Create and manage video elements such as shapes, text, and images.
• Asset Management: Load assets like videos and images from URLs or local sources.
• Variable Management: Define and manipulate variables within scenes for dynamic content.
• Event Handling: Subscribe to events such as block creation or updates for dynamic interaction.

API Overview

The APIs of CE.SDK are grouped into several categories, reflecting different aspects of scene management and manipulation.

Scene API:- Creating and Loading Scenes:

engine.scene.create();
engine.scene.loadFromURL(url);

• Zoom Control:

  engine.scene.setZoomLevel(1.0);
  engine.scene.zoomToBlock(blockId);

  Block API:

• Creating Blocks:

  const block = engine.block.create('shapes/star');

• Setting Properties:

  engine.block.setColor(blockId, 'fill/color', { r: 1, g: 0, b: 0, a: 1 });
  engine.block.setString(blockId, 'text/content', 'Hello World');

• Querying Properties:

  const color = engine.block.getColor(blockId, 'fill/color');
  const text = engine.block.getString(blockId, 'text/content');

  Variable API: Variables allow dynamic content within scenes to programmatically create variations of a design.

• Managing Variables:

  engine.variable.setString('myVariable', 'value');
  const value = engine.variable.getString('myVariable');

  Asset API:

• Managing Assets:

  engine.asset.add('image', 'https://example.com/image.png');

  Event API

• Subscribing to Events:

  // Subscribe to scene changes
  engine.scene.onActiveChanged(() => {
    const newActiveScene = engine.scene.get();
  });

Customizing the Svelte Video Editor

CE.SDK provides extensive customization options to adapt the UI to various use cases. These options range from simple configuration changes to more advanced customizations involving callbacks and custom elements.

Basic Customizations

• Configuration Object: When initializing the CreativeEditor, you can pass a configuration object that defines basic settings such as the base URL for assets, the language, theme, and license key.

  const config = {
    baseURL: 'https://cdn.img.ly/packages/imgly/cesdk-engine/1.51.0/assets',
    license: 'your-license-key',
    locale: 'en',
    theme: 'light',
  };

• Localization: Customize the language and labels used in the editor to support different locales.

  const config = {
    i18n: {
      en: {
        variables: {
          my_custom_variable: {
            label: 'Custom Label',
          },
        },
      },
    },
  };

• Custom Asset Sources: Serve custom video or image assets from a remote URL.

UI Customization Options

• Theme: Choose between predefined themes such as ‘dark’ or ‘light’.

  const config = {
    theme: 'dark',
  };

• UI Components: Enable or disable specific UI components based on your requirements.

  const config = {
    ui: {
      elements: {
        toolbar: true,
        inspector: false,
      },
    },
  };

Advanced Customizations

Learn more about extending editor functionality and customizing its UI to your use case by consulting our in-depth customization guide. Here is an overview of the APIs and components available to you.

Order APIs

Customization of the web editor’s components and their order within these locations is managed through specific Order APIs, allowing the addition, removal, or reordering of elements. Each location has its own Order API, e.g., setDockOrder, setCanvasMenuOrder, setInspectorBarOrder, setNavigationBarOrder, and setCanvasBarOrder.

Layout Components

CE.SDK provides special components for layout control, such as ly.img.separator for separating groups of components and ly.img.spacer for adding space between components.

Registration of New Components

Custom components can be registered and integrated into the web editor using builder components like buttons, dropdowns, and inputs. These components can replace default ones or introduce new functionalities, deeply integrating custom logic into the editor.

Feature API

The Feature API enables conditional display and functionality of components based on the current context, allowing for dynamic customization. For example, you can hide certain buttons for specific block types.

Plugins

Customize the CE.SDK web editor during initialization using the outlined APIs. For many use cases, this is sufficient, but for more advanced scenarios, plugins are useful. Follow our guide on building plugins or explore existing plugins like:

Background Removal: Adds a button to the canvas menu to remove image backgrounds. Vectorizer: Adds a button to the canvas menu to quickly vectorize a graphic.
