How to put music over an MP4
First, go to the "Add music to MP4" tool in your browser on your computer or smartphone. Then, upload your MP4 video by either dragging and dropping it into the editing window or clicking the "Open file" button. You can also add multiple video files by clicking the "Add" button and selecting other files.
To add an audio file as a separate track, click "Add" at the bottom of the editing window. Once added, you can crop and adjust the volume of the audio track by clicking on the "Sound" button. Additionally, if you need to remove the original audio track from your video, you can easily detach it.
Choose a format to encode
Access the encoding options by clicking on the gear icon next to the Save button. After adding music, please note that the video may take some time to be fully processed.
Save and continue your work
After you've added the music to your video, simply click on the "Save" button and wait for the tool to generate the new video file with the added music. Once it's done, you can choose to save the video file to your device or share it on your favorite social media platform. If you want to further enhance your video, you can use other editing tools like looping or adding text to make it the perfect final product.
