How can I add music or audio to video without watermark?

Video2X is an open-source AI video quality enhancement tool. Although it is not primarily designed for audio editing, you can use it in conjunction with other tools after enhancing the video quality to add audio to video without watermark.

Instructions: Launch the software and import the target video file. Select an AI model. Configure the scaling factor, frame interpolation settings, and output directory. Click “Start” to begin video enhancement.

Its advantages include: open-source software licensed under AGPLv3, no embedded watermarks or usage restrictions, support for batch processing, and all tasks running locally without the need to upload files to cloud servers.

Its drawbacks include: longer rendering times compared to commercial software, a steep learning curve for beginners, high GPU memory consumption during AI processing, and limited native support for Apple Silicon.

Notes

• Only video upscaling and frame interpolation are supported; audio tracks cannot be added directly to videos.
• Sufficient video memory is required. Insufficient video memory may cause the program to crash.
• Processing time increases significantly when using higher scaling factors and longer video clips.

This software can enhance the resolution and clarity of videos. After upscaling the video, you can use other software to add audio to video without watermark, and the final edited media file will not contain anything you don’t need.
