What is XLIFF?
XLIFF (XML Localization Interchange File Format) is a standardized XML-based format used to exchange translation data between different tools. It enables seamless integration with Translation Management Systems (TMS) and supports both machine and human translation workflows.
Step-by-Step: Translating Videos Using XLIFF in Synthesia
Step 1: Export Your Video as an XLIFF File
To begin the translation process:
Open your video project in Synthesia.
Click the three-dot menu next to the video title.
Select Download video as XLIFF.
Save the XLIFF file to your computer.
Step 2: Translate the XLIFF File Using a TMS
Use your preferred Translation Management System (TMS) to translate the script:
Upload the XLIFF file to your TMS (e.g., Phrase, Crowdin, Lokalise).
Translate the content using either machine translation or human translators.
Once complete, export the translated XLIFF file in the same format as the original.
Step 3: Import the Translated XLIFF File into Synthesia
To generate the translated video:
Open the original video in Synthesia.
Click the Translate button.
In the Translate modal, select Upload XLIFF files.
Choose the translated XLIFF file and click Translate.
Synthesia will automatically generate a new video with the translated script.
