The Commercial AI Sync Engine is an advanced processing option available on the 1-click Karaoke/Lyric Video Generator screen when you start a new project. It offers high accuracy for lyric synchronization and automatic transcription. You can, as always, choose to use the standard Base AI Sync Engine for cost-effective synchronization.
This guide explains when and how to use the Commercial Engine to save you significant time, especially when working with difficult audio or when you don't have the lyrics available. Below, we explain the two most common scenarios in which you will utilize the Commercial AI Sync Engine.
Use this feature when you need the platform to automatically generate your lyrics before syncing them to the audio.
Use this option when:
You do not have the lyrics written down.
You want to save time by having the platform automatically transcribe the audio instead of searching, copying, and pasting them yourself.
How to Use:
Upload your audio or video file.
Check the box labeled "I don't have lyrics - transcribe with AI."
A language selector will appear. Select the language of the song from the over 40 supported options.
The transcription and subsequent syncing process will cost 15 AI Credits per minute of audio.
Select the Commercial Engine when you have your lyrics but need superior timing accuracy to avoid manual adjustments in the Sync Editor.
Use this option when:
You have fast-paced vocals, rap tracks, or tracks with layered/complex musical arrangements that typically cause timing issues with the Base Engine (0.5 Credits/min).
You want to guarantee the highest level of accuracy and avoid spending time manually fixing synchronization issues altogether.
How to Use (On the Generator Screen):
Upload your audio or video file.
Paste your accurate lyrics into the text area provided.
Under the AI Sync Engine options, select the Commercial engine.
The enhanced synchronization process will cost 7 AI Credits per minute of audio.
Since the Commercial AI Sync Engine has different costs depending on the function you choose, it is helpful to plan your approach before uploading your song:
Goal | Song Type | Recommended Engine | Cost | Time Saved |
Lowest Cost Sync | Simple, slow-paced vocals, non-complex structure. | Base Engine | 0.5 credits/min | Minimal (might require manual adjustments) |
Max Accuracy Sync | Fast-paced, layered, or complex rap/vocal tracks. | Commercial Sync | 7 credits/min | High (reduces manual Sync Editor time) |
Lyrics Generation | Any song where you don't have the lyrics. | Commercial Transcription | 15 credits/min | High (avoids searching/copying time) |
For most cost-conscious users, searching and copying the lyrics yourself, and then using the Base Engine for simple songs, is the most budget-friendly workflow
All automatic processes on the platform, including transcription and synchronization, require AI Credits. For a full breakdown of how credits are used and managed, please consult our detailed guide:
