About

Useful Video Mixer

Features
Read full description

A handy video editing app has arrived that lets you overlay your favorite background music on videos and instantly change the mood. This simple app lets you add music or BGM to a video, preview the result, and then save it. Just adding music to travel memories, everyday moments, pet clips, or scenic videos can make your footage far more appealing. If your original video feels a little plain, adding BGM can make it more pleasant and easier to watch. You can overlay BGM while keeping the original video sound, or mute the original audio and save a version with only the music. You can also adjust the audio start position so the music begins naturally at the start of the video or at the scene you want to highlight. If you want to add music to a video, create a better mood, or make a nearly silent clip more engaging, give this app a try. 【How to Use】 1. Tap "Load Video" and choose the video you want to add BGM to. 2. Tap "Load Audio" and choose the music file you want to overlay. 3. Adjust the start position if needed, then tap "▶ Play" to check the result. 4. If you want to remove the original video sound, turn on mute for the original audio. 5. Tap "Mix and Save Losslessly" to export and save the video with BGM.
