Yes. Upload a video or pass a URL, call the ButterCut API, and receive time-synced subtitles in SRT, VTT, JSON, and other delivery-ready formats. The pipeline handles speech recognition, timing, and optional translation in a single async workflow.
ButterCut supports 20+ Indian and global languages including Hindi, Hinglish, Tamil, Telugu, Bengali, Marathi, Kannada, Malayalam, and English — with code-switching accuracy built for Indian content. Translate subtitles or transcripts into multiple target languages from one API request.
The API returns production-ready assets in SRT, WebVTT (VTT), JSON, TTML, and platform-specific formats for OTT, broadcast, and social. You can also receive plain transcripts and burned-in render instructions depending on your integration.
Sign up for an API key, upload media via secure endpoints, and poll or webhook for completion. Most teams integrate in under an hour: authenticate, POST a job, and fetch subtitles when processing completes. Our team can walk through CMS, MAM, or OTT workflow mapping on a demo call.

The API is built for batch and high-volume catalog processing. Async job queues, webhooks, and enterprise SLAs support OTT libraries, news archives, EdTech catalogues, and platform-scale ingestion pipelines.
Media is transferred over encrypted channels and processed in isolated pipelines. Enterprise customers can discuss data residency, retention policies, and security review requirements with our team before go-live.
Common integrations include OTT subtitle pipelines, EdTech accessibility layers, news clipping tools, podcast-to-video workflows, AI video editors, creator platforms, and internal media ops dashboards — anywhere video needs transcripts, subtitles, or multilingual delivery at scale.
