Video and transcript captioning data, timed to the frame

A video on its own tells a model what it sees. Add a written transcript and a caption track lined up to the timeline, and it also learns what was said and when. We collect the footage and produce the matching text as one linked package, scoped to what you're building.

The short answer

What is video and transcript captioning data?

Video and transcript captioning data pairs a video clip with a written transcript and a timed caption track, so a model can connect the spoken words to the exact moment they happen on screen.

This typically includes the source video, a full transcript of anything spoken, and caption text broken into readable lines with start and end times. Where the audio is unclear or overlaps, that gets flagged during review rather than guessed at.

This category maps to our Data collection service, with transcript work carried out under our Transcription service. See video data for the wider picture of what video work covers.

A model that has to reconcile two data types at once, what was said and what was shown, needs training examples where both sides are real and aligned, not stitched together after the fact. That alignment is often the actual source of errors once a multimodal system reaches production.

FAQ

Questions about video and transcript data

The datasets FAQ covers questions that apply across every category.

Is this raw speech-to-text output?

No. A review pass checks the transcript and caption timing against the video before delivery, not just a first machine pass.

Do captions come as a separate file or burned into the video?

Tell us which you need in the brief. Either way is possible, and the format is settled before production starts.

Can the transcript be in a different language than the video's audio?

Yes, through our Translation and localization service once the source transcript is ready.

Can you also label objects or scenes in the video itself?

Yes, through our Computer vision service, in addition to the transcript and caption track.

Can this be paired with other data types across a larger project?

Yes. Multiple data types, languages or domains can be combined under one brief and one named contact, using our 30,000+ person network and a track record of 150+ delivered projects.
