Reviews:

“I recently gave Vidsembly’s Video Music-Score a try while working on a few social media clips. Uploading my MP4 was straightforward, and choosing a music style took seconds. The tool instantly generated tracks that perfectly matched my video length, saving me the usual hassle of searching for the right music or editing tracks myself. The interface was friendly and intuitive, even for someone with no audio editing background. I appreciated the ability to preview the track, tweak the volume, and add fade effects before exporting. Overall, it made adding background music effortless and quick, with very little learning curve.”
