One platform — everything you need for video
Replaces a whole Premiere/CapCut toolkit for ads and entertainment videos: subtitle extraction, translation, text masking, rendering, dubbing — all built into one place.
Automatic subtitle extraction
AI reads hardcoded on-screen subtitles (OCR) or listens to speech (STT) and generates source subtitles with timestamps.
Any language, natural spoken style
Chinese, English, Korean, Japanese… to Vietnamese and back. 12 styles: natural, trendy Gen-Z, period drama, movie review…
Mask foreign text
Blur or cover multiple regions of the video; translated subtitles are placed right over the original text.
AI dubbing
322+ voices from every country (free) plus expressive premium Vietnamese voices; every line auto-synced to time.
Subtitle editor
Edit each line next to the video, reading-speed warnings, find & replace, autosave, export SRT/VTT/TXT.
Channel watermark
Add your channel name/logo to a corner of the video with custom font, color, and opacity.
Batch processing
Drop multiple videos at once, set up once — the whole batch runs extraction → translation back to back.
Voice previews
Listen to any voice before dubbing, filtered by country and gender.
Done in four steps
From a foreign video to a fully localized one — no editing software required.
Drop in your video
Pick the subtitle source (on-screen text or speech), source language, and translation style. Drag in multiple videos at once.
AI does the work
The system runs the whole chain: read metadata → extract source subtitles → translate. Watch progress live.
Review & fine-tune
Polish lines in the editor, pick a subtitle style, mark regions to mask original text, choose a dubbing voice and preview it.
Export & download
Render the subtitled video, the dubbed version, or download SRT/TXT files — ready to post anywhere.
