Who uses Video Translation
Real workflows from teams creating for global audiences
Brands going global
Remaking promo videos, launch keynotes and product demos for every language is expensive. Turn one master video into localized versions for every market, with brand messaging kept consistent.
Courses and e-learning
Recording every language yourself is not realistic. Clone the instructor's voice, translate line by line, attach a glossary for technical terms — bulk-localize your courses for global learners.
Cross-border e-commerce
One product video needs to work across multiple markets. Generate English, Spanish, Arabic and more from the same source clip — expand your TikTok Shop and Amazon ad library fast.
Creators going worldwide
Publishing one video to one language region leaves reach on the table. Dual-track dubbing and subtitles let you run YouTube and TikTok accounts across multiple languages simultaneously.
Short drama & film
Multi-character short dramas, web series and films — auto-separate each role and clone their voice, then batch-localize whole series for ReelShort, TikTok and more.
Podcasts & interviews
Multi-host podcasts and interviews — separate each speaker into their own dubbed track and ship multilingual versions to global listeners.
