Publishing Your Dub on YouTube
Short answer
To publish a dubbed video on YouTube, upload your dubbed audio as an extra track on your existing video. Viewers can then switch languages in the player's settings.
YouTube now allows creators to attach multiple audio tracks to a single video. This feature enables you to seamlessly publish your dubbed audio while keeping the original video intact. Here’s how to do it step by step.
How to dub your YouTube video into Portuguese (Brazil)
1. Prepare Your Dubbed Audio
Before uploading, ensure your dubbed audio is properly synchronized with the original video. Use DubFlow to generate your audio track in Portuguese (Brazil), ensuring clarity and quality.
2. Access Your YouTube Studio
Log into your YouTube account and navigate to YouTube Studio. This is where you can manage all your video content and settings.
3. Select the Video to Dub
In the YouTube Studio dashboard, go to the 'Content' section and find the video you want to add the dubbed audio to. Click on the video title to open the editing interface.
4. Upload Your Dubbed Audio Track
Scroll down to the 'Audio' section of the video settings. Here, you can upload your new audio track as an additional audio option. Ensure that you select the correct file format for compatibility.
5. Adjust Audio Settings
After uploading, you can modify the audio settings if needed. Make sure the dubbed track is set as an alternative audio option so that viewers can easily switch between languages.
6. Publish Your Changes
Once everything is set, click the 'Save' button to apply your changes. Your dubbed audio will now be available on the same URL, allowing viewers to switch languages directly from the player’s settings gear.
Publish your dub as a YouTube audio track
How the dub reaches your YouTube audience: Since September 2025 YouTube lets every creator attach multiple audio tracks to one video. Upload your dubbed audio as an extra track on the existing video — same URL, same view count, same thumbnail — and viewers switch language from the player's settings gear. This is the only platform where the dub lives on the original video instead of a re-upload.
About dubbing into Portuguese (Brazil)
Portuguese (Brazil) (Português (Brasil), ISO pt / por) has over 200 million speakers in Brazil — a large audience most creators never reach because their video is locked to one language.
A natural dub has to get tone and rhythm right, not just words — e.g. “Tudo bem?” (“How are you? / All good?”). DubFlow's per-line editor lets you fix any line and re-voice just that line in seconds, so the Portuguese (Brazil) version sounds like a person, not a machine.
