You can add translated video titles and descriptions to your videos. This helps make your videos more accessible to fans outside of your home country and helps you build a global audience. Your fans will be able to find your videos by searching in their own language, and we will show the title and description of the video on the watch page and everywhere else on YouTube in the right language, to the right users.

You can localize video metadata using the YouTube user interface, or you can upload a CSV file using the Video - Localization Update template.

To upload translated video metadata:

1. Download the Video - Localization Update template from the Content Delivery Templates page.

2. Complete the template with your translated data.

3. Save the file as .csv.

4. Click the Metadata Validator link that appears under CONTENT DELIVERY in the Creator Studio's left-side menu.

5. Select Choose file to upload your saved .csv file.

6. Click Validate.

   If you get red banner with validation errors, you need to make corrections in your file, save the changes, and re-upload it so that you see a "Successfully validated" green banner.

7. Upload your content using one of these methods:

   • If your template doesn't reference additional files (like captions or audio tracks): click the Upload and Make Live button on the validator page.
   • If your template references additional files: Use the Package Uploader to upload all of your files.
