How to Add Music to Video on Windows
Add music to establish tone, support a voiceover, create an intro or outro, or replace unusable camera sound. This guide explains how to plan the mix, control start and end times, protect speech clarity, and verify the final export.
Quick Answer
Open GiliSoft Video Converter, add the video, decide whether its original sound should remain, then add the authorized music or voice file. Set the audio start and end time, adjust volume, preview speech and transitions, and export a short test before processing the final video.
Decide What Should Happen to the Original Audio
The correct workflow depends on whether the camera sound, speech, or existing soundtrack still matters. Make this decision before adjusting the new music.
| Audio plan | Best for | What to do |
|---|---|---|
| Keep original audio and add quiet music | Tutorials, interviews, training, product demos | Preserve speech and lower the music enough that every word remains clear. |
| Replace original sound | Montages, silent screen captures, noisy camera footage | Remove or mute the source audio, then add the new track and verify the entire timeline. |
| Music only in the intro or outro | Courses, presentations, branded videos | Set an exact audio range and inspect the transition into or out of speech. |
| Music plus voiceover | Explainers, ads, demonstrations | Prepare separate files and keep the music lower under narration. |
| Sound effects at specific moments | UI demos, highlights, short social clips | Align each effect with the visible action and avoid sudden excessive loudness. |
Microsoft's editing guidance uses the same basic model: place audio on the timeline, trim its duration, change volume, and add fades where required. The important result is a controlled mix, not simply the presence of another audio file.
How to Add Music with GiliSoft Video Converter

- Add the source video
Open GiliSoft Video Converter, add the video, and listen to its original soundtrack from beginning to end. Note speech, noise, silence, and sections that already contain useful sound.
- Keep, lower, or remove the original audio
Retain camera sound when it matters, reduce it when music should sit underneath, or select no original audio when the replacement track should be heard alone.
- Add the authorized music, narration, or effect
Load the audio file and place it at the required point. Confirm that the selected file is the final licensed or approved version.
- Set the start and end time
Align the music with the intended video section. Trim excess duration and leave deliberate transitions around speech, scene changes, intros, and endings.
- Adjust volume and preview the mix
Check headphones and ordinary speakers. Speech should remain intelligible, and music should not jump abruptly between sections or clip at excessive levels.
- Choose output settings and export a test
Select the format, resolution, codec, and output folder. Check audio sync, beginning, middle, ending, picture quality, and file size before producing the final video or batch.

Music Timing and Volume Settings
| Setting | What it changes | Useful starting point |
|---|---|---|
| Start time | Where the new audio enters | Align it with the first intended frame and listen for accidental silence or an abrupt first beat. |
| End time | Where the music stops | End on a deliberate musical point or allow a fade rather than cutting a note or word in half. |
| Music volume | How strongly music competes with speech and source sound | Start low under narration, then test the quietest spoken passage and the loudest section of music. |
| Original audio volume | Whether camera sound remains prominent | Keep useful speech and ambience; mute unusable noise when the added track should replace it. |
| Fade in and fade out | How smoothly audio enters and leaves | Use a short transition where abrupt entry or exit feels distracting. More precise fades can be prepared in GiliSoft Audio Editor. |
Common Add-Music Workflows
Tutorial with speech and quiet music
Keep narration clear, lower music during explanations, and inspect every section where the speaker becomes quieter.
Product montage with replacement audio
Remove noisy camera sound, add one approved track, and align visual cuts with intentional points in the music.
Branded intro and outro
Use exact time ranges for opening and closing music while leaving the central lesson, meeting, or presentation uncluttered.
Voiceover plus sound effects
Place short effects at visible actions, preserve voice intelligibility, and avoid stacking several loud elements at once.
Fix Common Music and Audio Problems
| Problem | What to check |
|---|---|
| Music is louder than speech | Lower the added track and listen to the quietest spoken section, not only the opening narration. |
| Original sound and music clash | Reduce or remove the source audio, trim unwanted camera noise, or use music only where original sound is unnecessary. |
| Music ends too early | Check the added track's end time. Extend, repeat, or prepare a longer licensed track rather than leaving accidental silence. |
| Music is cut off abruptly | Move the endpoint to a natural phrase boundary or prepare a fade-out before import. |
| Audio is out of sync | Verify the source frame rate and duration, inspect the first and last synchronization points, and test settings closer to the source. |
| The audio file will not import | Convert it to a supported format such as MP3, WAV, AAC, or M4A, then confirm that the file plays normally before adding it again. |
| The upload receives a copyright claim | Review the track's actual license, attribution, territory, platform, monetization, and duration terms. Re-editing or changing volume does not remove copyright. |
