Batch Merge Video and Audio

If you have many videos and corresponding audio files and want to embed the audio into the videos one by one, manual operation would be tedious and inefficient. This feature allows you to batch embed audio into videos.

Usage

1. Create a folder and move the videos and audio files to be merged into it.

2. The videos and audio files to be merged must have the same name (without the extension). The program uses this to determine which audio file to embed into which video.

   For example, if the full name of the video is 001.mp4, the name without the extension is 001. Then the audio file you want to embed into this video must be named 001. If the audio is in wav format, the full name will be 001.wav. If it is in mp3 format, the full name will be 001.mp3.

   During processing, after obtaining 001.mp4, the software will remove the extension to get 001 and then search in the folder for 001.wav/001.mp3/001.flac/001.aac/001.m4a. If found, it will embed that audio into the video 001.mp4.

3. Select the folder in the software interface.

4. Set whether to keep the original sound in the video. If selected, the processed video will have two sounds: the original sound from the video file and the sound from the audio file.
