Dub Facebook video ads and content
Upload your video ad or branded content. AI clones the speaker's voice, translates, and syncs lips. Localize campaigns for 3B+ Facebook users in 30+ languages.
How it works
Upload your video
Upload your Facebook video ad, product demo, or branded content. DubSync extracts the audio and generates the transcript.
Select target markets
Choose languages for each market you want to reach. DubSync translates, clones the voice, and produces localized audio.
Download and launch
Preview dubbed versions with lip sync. Download MP4 files and upload them to Ads Manager or your Page for each language audience.
Key benefits
Lower cost per acquisition
Localized video ads perform better than subtitled versions. Native-language ads drive higher click-through rates and lower CPAs across markets.
Scale campaigns globally
Dub one creative into 30+ languages instead of producing separate videos for each market. Save production time and budget.
Consistent brand voice
AI voice cloning keeps the same speaker voice across every language, maintaining brand consistency in all markets.
Works with any video format
DubSync accepts MP4, MOV, AVI, WebM, and MKV. Output is MP4, ready for Facebook Ads Manager or organic posting.
