Karaoke Video Generator – How to Use It

 

1. Upload & audio pre-processing (always automatic) :

• Your video is analyzed → track extraction of the full (original sound).
• Smart separation into instrumental + vocals thanks to our advanced AI technology.

2. Lyric management — two possible paths :

• Case 1 — You provide a text file (.txt) containing the lyrics, at the same time as the video:
  • No AI transcription is launched.
  • The file defines exactly the subtitle lines (length, breaks, punctuation).
  • Warning : spelling, line timing and formatting must be finalized before upload — modifications impossible after this step.
  • Direct access toword-by-word alignment then to thevideo generation interface.
• Case 2 — No lyrics file :
  • Automatic transcription of vocals by our AI speech-to-text.
  • Simultaneous retrieval of official lyrics from Spotify, Genius et Lrclib (if available).
  • Two side-by-side interfaces await you:
    • Left: raw AI transcription (to be corrected and formatted).
    • Right: official lyrics (buttons to choose the source).
  • Correct any errors then cut your lines (each line of text = one line displayed on the screen).
  • Validate → automatic word-by-word alignment with an accuracy of approximately 95%.
  • 👉 Bonus : in 1 click, the raw transcription can be automatically corrected and formatted by our specialized AI model.

3. Precise realignment (the strong point!) :

• Ultra-readable vocal waveform with annotations word by word.
• The initial alignment is already about 95% accurate thanks to our AI.
• Easily drag-stretch each word to perfectly adjust held notes, vibratos, dragging words → achieve 100% accuracy.
• Result: the karaoke highlight follows exactly the actual duration of the singing.

4. Visual customization of subtitles :

• Active line (karaoke effect) : color of sung / passed (e.g., #FFD700) vs. remaining / future (e.g., #FFFFFF, #00FFFF…).
• Outline et drop shadow customizable (highly recommended for readability on all backgrounds).
• Various fonts available, and additions possible upon request.
• Static lines (the lines preceding the current one): identical or different settings.
  • Sync button to copy everything with one click.
• Number of visible lines : from 1 to 8 simultaneously.
• Block position : Top / Center / Bottom + margin as % from the edge.
• Accessibility : high contrast and highly legible fonts available.

5. Automatic subtitle translation (optional) :

• Display the real-time translation of the sung line in the language of your choice.
• Ability to correct and customize the AI-generated translation.
• Various fonts, outline, and drop shadow also customizable on translated lines.
• Block position: Top / Center / Bottom + margin as % from the edge.
• Karaoke effects also available on translated subtitles :
  • Word by word.
  • Letter by letter.
• AI bilingual neural word-by-word alignment (1 credit option):
  • Surgical synchronization : each word of your translation syncs with millimeter precision to the original voice — no more subtitles scrolling too fast or out of sync with the melody.
  • Advanced AI models : powered by specialized models BinaryAlign (optimized language pairs) and mBERT (extended multilingual coverage), our engine matches the translation to the exact rhythm of the performer.
  • Immersive multilingual karaoke : offer your audience an experience as fluid and natural as in the original language, even when they sing in a language they do not master.

6. Video settings & encoding :

• Codecs :
  • H.264 → universal compatibility.
  • H.265 → significantly higher compression.
• Formats : MP4 (most universal), MKV, MOV.
• Constant Rate Factor (CRF) adjustable.
• Encoding preset (de Medium à Ultra Fast) :
  • Very Fast / Super Fast / Ultra Fast → fast encoding, larger file → ideal for previews and tests.
  • Medium → longer encoding, but a much lighter and higher quality file → preferred for the final video.

7. Complete audio mixing & advanced processing :

• Independent volume for each track: Full / Instrumental / Vocals.
• Global Master Volume.
  • → Pure karaoke (instrumental only), original version, custom balance… everything is possible! 🎛️
• Advanced audio processing available for each track:
  • Automatic amplification.
  • Frequency cleaning.
  • Parametric equalizer.
  • Dynamic compressor.
  • Volume limiter.
  • Stereo widening.
  • Bass boost.
  • Crystalizer (audio restoration).

8. Custom logo / watermark (optional) :

• Upload your image : karaoke bar logo, Hen/Stag Party photo, birthday text, commercial brand…
• Position : fixed or animated (choose multiple positions: top left, center, bottom right…).
• Pause time at each position and transition time (fade).
• Opacity, margin, and resizing factor fully adjustable.
  • → Perfect for customization without ever being intrusive.

9. Rates & previews in detail :

• Autonomous generation : 5 credits (≈ €5) per complete video.
• Previews :
  • Duration from 15 to 45 seconds, starting from the beginning or centered on the video (to see subtitles even if the intro is long).
  • The first 15 previews are included for free.
  • Beyond that: 1 credit for 15 additional previews (anti-abuse measure).
