What is VidDub?

VidDub is an AI video translation tool from szsoftwell (Shenzhen Netsoft Information Technology Co., Ltd). Upload a video (MP4, MOV, MKV, AVI, FLV or WebM, up to 2 GB), pick the source and target language, and VidDub transcribes the speech, translates it and burns synced subtitles into the video — monolingual or bilingual, with high-level style controls (position, color, size, background). Subtitle files can also be exported when you have minutes. As an optional second step you can add AI voiceover/dubbing: preview voices from the VidDub voice library, generate a track timed to the original speech, and download; you can re-dub with a different voice. Burned-in subtitles stay in the video. It supports 17 source languages and 18 target languages (Traditional Chinese is target-only), runs in any desktop or mobile browser with no install, and also has iOS and Android apps. Sign-in (Google or Apple) is required before uploading. After sign-in, eligible short videos (≤10 minutes) can complete translation as a free preview; full downloads are paid. Basic dubbing is free, with no extra charge; Premium dubbing is paid in the iOS and Android apps.
