Product Overview

Introducing the Bulk Video Audio Replacer, the definitive Windows application for content creators, video editors, social media managers, and anyone looking to streamline their video production workflow. Built with C# WPF and powered by the industry-standard FFmpeg engine, this tool is designed to solve one of the most tedious tasks in video editing: replacing the audio track across multiple video files. Forget the hours spent manually editing each video one by one. With our tool, you can apply a single audio track to hundreds of videos in just a few clicks, saving you invaluable time and effort.

Key Features:

1. Powerful & Unlimited Batch Processing

• Process Hundreds of Files at Once: Select an unlimited number of video files from your computer. Our application is built to handle large queues without breaking a sweat.

• One-Click Audio Application: Choose a single MP3 file to serve as the new master audio track for all your selected videos.

• Organized Output: Designate a specific output folder to keep all your newly processed videos neatly organized and separate from the original source files.

2. Intelligent & Automatic Audio Synchronization

• Automatic Audio Looping: If a video is longer than your MP3 file, the software automatically loops the audio track seamlessly until the end of the video. Perfect for adding background music to long-form content.

• Precise Audio Trimming: If a video is shorter than your MP3, the audio is automatically and precisely cut to match the exact duration of the video, ensuring a clean and professional finish every time.

• "Set It and Forget It" Workflow: Once you start the process, the application handles everything. No further intervention is required.

3. Lossless Quality & Format Preservation

• Zero Quality Loss (Video Passthrough): Our tool leverages FFmpeg's powerful stream-copy feature. This means your video is never re-encoded. The original video quality, resolution, and data are passed through to the new file untouched.

• Original Format & Resolution Kept: Whether your videos are .mp4, .mov, .mkv, or any other format, the output will be in the exact same format. 4K stays 4K, HD stays HD.

• Blazing-Fast Processing: Because we don't re-encode the video, the process is incredibly fast—limited only by your hard drive's read/write speed. This is significantly faster than any traditional video editor.

4. User-Friendly Interface & Reliable Operation

• Clean and Intuitive Dashboard: A simple, no-nonsense interface makes the tool incredibly easy to use, even for non-technical users.

• Live Progress Monitoring: The status bar provides real-time feedback, showing you which file is currently being processed and the overall progress (Processing (5/100)...).

• Clear Error Reporting: If an issue occurs with a specific file, the application notifies you with a clear error message, including technical details from FFmpeg for easy troubleshooting.

• Portable & Self-Contained: No installation required. The program runs directly from its folder, as long as the ffmpeg.exe file is in the same directory.
