Generate subtitles automatically, then make them right.

How automatic subtitle generation works

Subtitles are a transcript split into short, timed pieces called cues. Media2Text first transcribes the speech with timestamps for every segment, then builds caption cues from that timing. Because the captions come from the transcript, you can correct a word once in the transcript and every caption that contains it is fixed before export.

Why review matters

Automatic captions are a strong first draft. Viewers notice mistakes quickly, especially in names, brand terms and numbers. A short review pass makes the difference between captions that look automatic and captions that look professional:

• Correct repeated names and terms with find and replace.
• Play back fast dialogue and overlapping speakers.
• Check the first and last minute for timing.
• Decide whether speaker names belong in the captions.

Readable captions

Good captions are one or two short lines that stay on screen long enough to read. If a passage is very fast, split long cues at natural pauses. The SRT subtitle guide covers line length, reading speed and common problems in detail.

Where to use the subtitle file

SRT is accepted by most video editors and upload forms, including YouTube Studio. VTT is the standard for HTML5 web players. Social platforms differ; some accept caption files and others expect captions burned into the video. Generate both from the same transcript if you publish in several places. Need to convert between them later? Use the free SRT to VTT converter or fix an offset with the subtitle time shifter.

Subtitles for many languages

To reach more viewers, create a translated transcript track and export subtitles in that language with the original timing. Translated text can be longer than the original, so re-check reading speed. See translate video subtitles.

Accessibility

Captions for viewers who are deaf or hard of hearing often describe important sounds such as [music] or [applause]. Speech recognition captures spoken words only, so add these descriptions manually where they matter.

Reviewing the transcript before you use it

Automatic transcription gives you a fast, timed draft. Before you publish, quote or share it, spend a few minutes on the parts that matter most. Rename the speaker labels so every export shows real names. Use find and replace for names, brands and technical terms that appear more than once. Then click the timestamps for the passages you will actually quote and listen to them: overlapping voices, background music and fast speech are where errors cluster. The editor keeps the text and the audio together, so checking a line takes seconds instead of scrubbing through the whole recording.
