Make a music mix video in Auvilizer

This guide walks through the basic Auvilizer workflow: start a project, import local audio, arrange the mix, build a visual scene, and render a finished MP4 video.

Recommended first project Start with one or two local audio files and one visualizer scene. Add more tracks, text, and image layers after the first render succeeds.
01

Create or open a project

Use Home to create a new project file or continue an existing one.

02

Import audio

Add local music files to the Library and confirm they preview correctly.

03

Build the mix

Send tracks into the Sequence timeline, then adjust timing and fades.

04

Design and render

Create a visual scene, check output settings, and render the MP4.

Before You Start

Prepare a simple first render

Have ready

  • One or two local audio files on your PC.
  • A project save location you can find again.
  • An output folder with enough free disk space.

Keep it simple

  • Use one visualizer scene for the first test.
  • Render a short range before rendering a full mix.
  • Fix missing-file warnings before export.
1

Create a project

Open Auvilizer and use Home to create a new project. Choose a save location first so project recovery, manual saves, and future edits stay tied to a known file.

  1. Select New Project.
  2. Choose where the project should be saved.
  3. Confirm the project opens before importing audio.

If you are returning to a previous session, use Open Project or Continue Current Session instead of starting over.

2

Import local audio in Library

Library is where Auvilizer keeps project audio sources. Import the files you want to use, then preview them before placing anything on the timeline.

  1. Go to Library.
  2. Select Import Audio.
  3. Add your local music files.
  4. Click a file and preview it to confirm the source is playable.

If a file is marked missing, reconnect or re-import it before rendering. Auvilizer renders from local source files.

3

Arrange the mix in Sequence

Sequence is the editing timeline. Use it to decide what plays, when it starts, how clips overlap, and which range should be rendered.

  1. Add selected Library tracks to the Sequence timeline.
  2. Reorder clips into the final playback order.
  3. Trim clip starts or ends when needed.
  4. Add fade in, fade out, or crossfade adjustments.
  5. Set the render range to the part of the mix you want to export.

Playlist staging is only preparation. The Sequence timeline is the source of truth for the final video timing.

4

Build the visual scene

Scene controls what viewers will see. Start with a visualizer layer, then add supporting image, text, or timestamp layers only when the basic visual output is working.

  1. Go to Scene.
  2. Add a visualizer layer such as Bar Spectrum or Radial Crown.
  3. Adjust color, material, response, or layout in the inspector.
  4. Add image or text layers if the video needs branding or context.
  5. Preview the sequence and confirm the visual reacts as expected.

Keep the first scene readable. A strong visualizer and clean text are usually better than a crowded layer stack.

5

Render the MP4

Rendering turns the selected timeline range and scene output into a video file. Review readiness before starting the export.

  1. Go to Rendering.
  2. Choose the render profile, output format, frame rate, and audio settings.
  3. Select an output path.
  4. Resolve any blocked reasons shown on the page.
  5. Select Start Rendering.
  6. Open the exported file and check audio, timing, and visual output.

For a first test, render a short range. Once the result looks right, render the full music mix video.

Troubleshooting

Common problems to check first

No audio in preview

Confirm the source file still exists, preview the file in Library, then check that the clip is inside the current render range.

Render button is blocked

Check the readiness message. Common causes are no audio, missing source files, no output path, or unsupported scene content.

Output looks different

Test a short render range and compare the Scene preview with the rendered file. Keep unsupported or experimental layers out of the first release-ready render.
