angular ej2 file-upload syncfusion uploader video-preview

Enhancing user experience in file uploads is essential for modern web applications, and the Syncfusion EJ2 Angular File Upload component makes it easy to implement advanced features like client-side video previews. This guide demonstrates how to add video preview functionality to the Syncfusion Angular File Upload control, allowing users to visually verify their selected video files before initiating the upload.

Use Cases

  • Video Content Platforms: Allow creators to preview videos before uploading to ensure quality and correctness
  • Media Management Systems: Enable administrators to verify video content and metadata before storage
  • Educational Platforms: Help instructors validate lecture videos and educational content before submission
  • Marketing Dashboards: Allow teams to review promotional videos before uploading to campaigns
  • Admin Panels: Provide robust media management with pre-upload verification

Prerequisites

Implementation Overview

The solution uses these key features:

  1. Configure Syncfusion Angular Uploader with autoUpload="false" for manual upload control
  2. Handle selected event for file metadata extraction and validation
  3. Use URL.createObjectURL() to create temporary object URLs for video preview
  4. Display video preview using HTML <video> tag within custom templates
  5. Manage upload lifecycle with event handlers (beforeUpload, progress, success, failure)
  6. Implement file cleanup using URL.revokeObjectURL() to free memory resources

Features

  • ? Client-side video preview before upload
  • ? Restricted file type support (.mp4, .avi, .mov, .wmv, .flv, .mkv, .webm, .mpeg)
  • ? Real-time upload status updates with progress percentage
