What Are Captions and How Do You Get Them for a Video?

Captions are the on-screen text that displays a video's spoken dialogue (and often sound effects or speaker labels) synchronized to the audio. You get them in one of two ways: the platform generates them automatically from the audio track, or a person writes them manually. If you need captions for a video that doesn't have them, a transcription tool like Scribe can produce them from the video and let you download the result as an SRT (caption) or TXT (plain text) file.

Captions vs. transcripts vs. subtitles

These three terms get used interchangeably, but they describe different things:

| Term | What it is | Timing | Typical use | |---|---|---|---|---| | Captions | On-screen text for dialogue plus relevant non-speech audio | Synced to the video | Accessibility, silent viewing | | Transcript | A full text document of everything said | Usually unsynced | Reading, searching, repurposing | | Subtitles | Translated or same-language text for dialogue | Synced to the video | Watching in another language |

The practical difference: a transcript is a document, while captions and subtitles are timed overlays. Captions also carry non-dialogue information (like "[music]" or a speaker name), whereas subtitles typically render only the spoken words. In many tools the same source file feeds all three — you transcribe once, then export as SRT for captions or TXT for a transcript.

Auto-generated vs. manual captions

Auto-generated captions are produced by speech-recognition software. They're fast and cost nothing to create, but accuracy varies with audio quality, accents, overlapping speakers, and background noise. A common user observation in Scribe's reviews is that punctuation was still being refined — one reviewer specifically said they were "really looking forward to the punctuation feature." That's a typical trade-off with automatic captions: the words are largely right, but formatting needs a pass.

Manual captions are written or corrected by a person. They're more accurate and better formatted, but slower and usually more expensive.

For most casual use — reading back a lecture, searching a long interview, or getting a rough caption track — auto-generated captions are enough. For publishing, legal, or accessibility-compliance purposes, plan on editing the automatic output.

How to generate captions from a video

The general workflow is the same across tools. Using Scribe as the example:

1. Provide the video. Paste a video URL or upload the file. Scribe's page shows sample videos (TED talks, Veritasium, MrBeast) you can try before using your own.
2. Let it transcribe. The tool processes the audio and returns a transcript on the page. Scribe reports support for 50+ languages and over 1M videos transcribed.
3. Review the text. Check names, technical terms, and punctuation, since automatic output often needs corrections.
4. Export in the format you need. Scribe offers Copy, TXT, and SRT. Choose SRT if you want a caption file you can upload to a video platform; choose TXT if you just want the text.

Expected result: an SRT file with timecoded lines you can attach to the video as a caption track, or a TXT file for reading and searching.

Common snags:

• Poor audio (music, crosstalk, heavy accents) lowers accuracy — clean audio or a manual pass fixes most of it.
• If the video already has captions, you may be able to pull the existing track instead of re-transcribing; Scribe notes support for both auto and manual captions.
• Punctuation and speaker labels are the most frequent cleanup items.

Multi-language captions and switching

If a video has multiple caption tracks, viewers switch between them with one click — Scribe lists instant language switching and 50+ supported languages as a feature. This matters in two cases: you want captions in a language other than the spoken one, or you want to compare an auto track against a manual one. When only one track exists, you generate the additional language by translating the transcript rather than re-recording.

Choosing an approach

• Just need the words to read or search: generate a transcript and export TXT.
• Need captions to display on the video: export SRT and upload it as a caption track.
• Need accuracy for publishing or compliance: start with auto-generated captions, then edit manually.
• Need another language: use a tool with multi-language support and switch or translate the track.

Scribe is free to use according to its site and is used by 550K+ creators, with a Chrome extension available; a "View Plans" link points to paid options, so check the pricing page if you need features beyond the free tier.
