Cara Add Captions to Video

  1. 1

    Add your video

    Drop in an MP4, MOV or WebM with an audio track — it's read in your browser, never uploaded.

  2. 2

    Transcribe and review

    Whisper transcribes the speech into timed caption lines. Fix any mistakes right in the list before you burn them in — corrections after that point mean starting over.

  3. 3

    Style and export

    Pick a position and size, then download SRT/VTT subtitle files, or burn the captions directly into the video as a new file.

Add Captions to Video — soalan lazim

Is my video uploaded?+

No. Both the Whisper transcription and the caption burn-in run entirely in your browser. The video never leaves your device.

Which browsers work?+

Transcription works broadly. Burning captions into the video needs WebCodecs — Chrome, Edge or Safari 17+. You can still download SRT/VTT subtitle files anywhere transcription works.

Can I fix mistakes before burning them in?+

Yes — every caption line is editable after transcription. Fix anything Whisper got wrong before you burn it in, since that step is permanent.

Does burning in captions reduce video quality?+

Slightly — it's a full re-encode of the video, the same trade-off as Compress Video. Pick a lower resolution source if file size matters more than quality.

Adakah anda memuat naik fail saya ke pelayan?+

Tidak — setiap alat di sini memproses fail anda sepenuhnya pada peranti anda, dan tiada apa dimuat naik ke pelayan. Satu-satunya pengecualian ialah alat AI, yang menghantar teks yang diekstrak (bukan fail) ke Claude untuk melakukan kerjanya.

Adakah terdapat had saiz fail?+

Kami tidak mengenakan had buatan, tetapi kerana pemprosesan berlaku dalam pelayar anda, fail yang sangat besar (500+ MB atau 1,000+ muka surat) dihadkan oleh memori peranti anda, bukan oleh kami.
