A leading U.S.-based global eCommerce company needed to localize over 1,000 marketing product videos per month into 12 languages spanning Asia, Europe, and the Americas. The requirements were strict: voice-over, subtitles, and on-screen graphics in every language, with zero tolerance for video length expansion, 97%+ quality scores, SOC 2-level data security, and 24/7 client support. The existing budget could not support the volume without compromising one of those criteria. Compass Languages built a hybrid custom video localization workflow combining AI-driven automation, MP4 deconstruction, voice tagging, AI voice integration, audio sync tools, with human-in-the-loop translation review and language-specific AI tool validation. Automated routing moved files between linguists and reviewers for final QA, keeping the workflow tight even at high volume.
