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

The software is designed for Windows and supports adding audio tracks to your video projects. To add audio to video, you can import an audio file—like music or a voice recording—and place it on the timeline alongside your video. The editor also includes features like muting the original video sound, adjusting audio volume, and recording voiceovers directly within the program.

How to add audio to video:

VirtualDub2 is not a typical drag-and-drop video editor; it's more of a powerful video processing utility. This means the process of learning how to add audio to video in VirtualDub2 is a bit different from other software.

Here’s the key information you need to know:

1. Audio Replacement is Possible: The software supports basic audio operations, such as adding, replacing, or removing audio tracks from your video.
2. Watermark-Free: Since it's entirely free and open-source, you can add audio to video without watermark concerns.
3. Understanding the Workflow: To successfully add audio to video and export to formats like MP4, you need to follow a specific procedure. A user on a forum outlined these steps for adding audio and exporting to MP4:

• For the video, set it to "Direct Stream Copy" to avoid re-encoding.
• For the audio, set it to "Full processing mode".
• Select an audio compression format like AAC or MP3. This is a critical step, as the software cannot export PCM (uncompressed) audio to an MP4 container.
• Finally, when saving, choose "MP4 Faststart" as the "Save as type" to get an MP4 file.
