This NestJS application provides a service for uploading and merging multiple video files into a single video file using AWS S3 for storage and FFmpeg for merging. The main features include:

• Merge Videos: Uses FFmpeg to merge the uploaded videos into a single output video file with a specified resolution and frame rate.
• AWS S3 Integration: Utilizes AWS SDK to upload the merged video file to an S3 bucket, providing a publicly accessible URL for the merged video.
• Error Handling: Implements error handling to manage exceptions during the upload and merge process, ensuring robustness and reliability.
