Sanfausone - Video Localizer

Turn your videos into captioned clips, karaoke tracks, creative loops and localized content with Sanfausone.

Choose a service, select your media, customize the settings and submit your render. Sanfausone processes your file online and provides a downloadable result—without requiring an account or subscription.

FIVE TOOLS FOR YOUR CONTENT

• Basic subtitles
Add readable captions to your videos. Choose the source language and subtitle style.

• Karaoke
Create karaoke-style videos with synchronized lyrics. Choose a visual theme and optionally remove vocals to produce an instrumental track. Use content you own or have permission to process.

• Video looper
Extend a short video to your chosen duration for repeating scenes, backgrounds and creative clips.

• Localized subtitles
Translate spoken content into another supported language and add subtitles to help your videos reach more viewers.

• Localized dubbing and voice-over
Create a translated voice track with selectable voices. Customize options such as retaining the original voice quietly and including localized subtitles.

SIMPLE PRICING BY VIDEO LENGTH

Each service has three fixed-price duration tiers:

• Short: up to 5 minutes
• Standard: over 5 minutes and up to 10 minutes
• Extended: over 10 minutes and up to 15 minutes

The app analyzes your uploaded media and selects the matching tier. Google Play displays the price before you pay. You purchase one render at a time—no subscription or credit wallet is required.

The Android version supports source media up to 15 minutes long. Loop output is also limited to 15 minutes.

TRY THE DEMO

Explore the included sample video and its prerecorded captioned result. Watch or download both, even when the renderer is unavailable. Load the sample into the studio to explore settings and try the live rendering workflow when the service is online.

FREE RETRY VOUCHERS

If processing fails, Sanfausone provides a single-use retry voucher valid for seven days. Enter it in the voucher field to submit another render without paying again. Voucher entry is available alongside the normal purchase option.

DOWNLOAD AND KEEP YOUR RECOVERY LINK

Follow your render’s progress and download the completed file. Save its private recovery link or QR code so you can return while the file remains available.

Rendered files are temporary and available for approximately 24 hours. Download your result promptly. Anyone with your private recovery link can access the associated render, so keep it secure.

IMPORTANT REQUIREMENTS

Live rendering requires an internet connection and an available online renderer. Keep the app open while uploading your source file or saving your download. The offline demo uses bundled, prerecorded videos and does not perform live processing.

Create, caption, translate and loop your next video with Sanfausone.
