Opusonix supports music projects that involve video, such as film scoring, trailer music, game cinematics, advertising spots, or any workflow where audio must be evaluated against picture. By uploading video files to your project, Opusonix can render a synchronized video preview while you review and compare multiple audio versions.
This article explains how to import video files, enable video preview, and perform A/B comparisons between audio and video versions.
Uploading Video Files
Video files are imported using the Media Tracks pod, the same location used for audio files.
Method 1 — Drag and Drop
Locate the Media Tracks pod in your project.
Drag your video file (for example,
.mp4) directly into the pod.The file will automatically be imported into the project.
Method 2 — File Selection Dialog
Click the "+" button in the Media Tracks pod.
Select the video file from your computer using the file dialog.
Confirm the selection to upload the file.
Both audio and video files can be uploaded using either method.
Switching to the Video Mode
If your project contains one or more video files, Opusonix can display a synchronized video preview.
To enable this:
Locate the mode selector in the top bar.
Switch the interface to Video Mode.
When Video Mode is active, the Video Preview Pod will appear in the workspace. This pod renders the currently selected video file.
Want to see a bigger video feed? Click on the "Maximize" button near the top right corner of the Video Preview Pod.
Video Playback with Audio Track Comparison
One of the primary workflows supported by Opusonix is comparing multiple audio versions against the same video.
Typical use cases include:
Comparing mix revisions
Testing alternate music cues
Evaluating reference tracks
Reviewing client revisions
Example Workflow
Upload your video file to the Media Tracks pod.
Upload multiple audio versions (for example: Mix v1, Mix v2, Reference).
Switch to the Video Mode.
Start the playback.
Click to activate various audio tracks during playback to hear the differences.
This allows you to quickly determine which mix or version works best with the picture.
Comparing Multiple Video Versions
Opusonix also supports A/B comparison between different video edits.
To do this:
Upload multiple video files to the Media Tracks pod.
Switch to the Video Mode.
Start the playback.
Use the Video Preview Pod to switch between available video files.
This allows you to evaluate how your audio performs against:
Different video edits
Alternate cuts
Updated picture locks
Timing changes
Video switching allows you to test synchronization and musical impact across different visual versions.
Waveform Rendering for Video Audio Tracks
If the uploaded video file contains an audio track, Opusonix will attempt to extract and display its waveform in the Media Tracks pod.
This waveform behaves the same way as regular audio tracks and allows users to:
Visually align cues
Place timestamped comments
Make time selections
When the Media Track Displays "N/A"
In some cases, the waveform for a video file may display "N/A" instead of a waveform. This is expected behavior under certain conditions.
Case 1 — Video Contains No Audio Track
If the uploaded video file does not include an audio track, Opusonix cannot generate a waveform.
In this case:
The Media Track will display "N/A"
Video playback will still function normally.
Case 2 — Unsupported Audio Codec
If the video file contains audio encoded with a codec that cannot be decoded natively by the browser, waveform extraction may fail.
In this situation:
The Media Track will also display "N/A".
However, the following features will still work normally:
Video playback
Audio/video synchronization
Timestamped commenting
Time selections
Audio A/B switching
Notes and Best Practices
For the best experience when working with video:
Use widely supported formats such as MP4 (H.264 video).
Ensure audio tracks use common browser-supported codecs when possible.
Upload final picture edits when evaluating mix or music timing decisions.
