Two languages,
one timeline.
Drop in a video or paste a link. DualCue transcribes the speech, aligns it to the timecode, and gives you back the original and the translation stacked in a single subtitle file.
MP4 · MOV · MKV · MP3 · WAV · M4A — or a public YouTube / X link
Three steps, no editing suite.
Bring the audio
Upload a file from your machine, or paste a public YouTube or X post URL. Audio-only files work the same way.
Transcribe & align
Whisper large-v3 turbo produces the transcript with word-level timestamps, so cue boundaries land on pauses in speech rather than arbitrary character counts.
Translate & export
Pick a target language and get a stacked bilingual file — .srt, .vtt, .ass or plain text. Or burn the captions into the video.
Built around the
subtitle file.
Not a general video editor. One job, done precisely: getting accurate, readable captions out in the two languages you need.
Timestamps are aligned per word, then grouped into cues that break on natural pauses. No drifting captions on long takes.
Source language on the first line, translation on the second, in one file — so you can read along without switching tracks.
If a YouTube video already ships author-written captions, those are pulled and translated directly instead of re-transcribing the audio.
Whisper handles 90+ spoken languages for transcription. Mixed-language speech is detected per segment rather than forced to one guess.
Plain formats for players and platforms, ASS when you need styling control, plain text when you just want the transcript.
Hardcode the captions into the video with control over font, size, position and outline — for players that ignore sidecar files.
