DualSubGenerator

Dual Subtitles Generator is an AI-powered web application that automatically creates subtitles in two languages at the same time for any video you upload. Instead of running separate transcription and translation steps, it takes a single video file, detects and transcribes the spoken audio in the original language, and then translates that transcript into your chosen target language, producing two synchronized subtitle tracks ready to download. The whole process runs in the browser, requires no software installation, and is aimed at turning ordinary videos into multilingual content in a few clicks. At its core the tool combines automatic speech recognition with machine translation. The AI analyzes context and terminology so the translated lines read naturally rather than word for word, and the platform advertises a 95%+ accuracy rate for clear audio. Timing is preserved across both languages, so viewers see smooth, professionally aligned subtitles instead of the mismatched captions that manual workflows often produce. Language coverage is broad: the service supports more than 50 languages, including English, Spanish, Mandarin, Arabic, French, German, Japanese, Portuguese, Korean, Russian, Italian, Dutch, Hindi and Turkish, and you can generate dual subtitles for essentially any supported pair. Accepted input formats include MP4, MOV, AVI and WebM files up to 500 MB, covering both very short clips and longer recordings. Finished subtitles can be exported as SRT, VTT, ASS or JSON, formats that work with YouTube, TikTok, Instagram Reels, Vimeo and most editing programs. Access is credit based. New users can sign in with email, Google or GitHub, then buy non-expiring credit packages to unlock bilingual subtitle generation whenever they need it. According to the site, uploaded videos are processed securely and deleted automatically within 24 hours under a zero-retention policy, and an online editor lets you adjust timing and fix translations before exporting. The result is a lightweight, focused alternative to hiring translators or juggling separate captioning and translation services.
