Generate styled, burned-in subtitles at scale with our subtitle API
VEED's subtitle API takes a video URL, auto-transcribes the audio, applies a style preset, and returns a video with subtitles burned in. No manual timing, no separate styling step, no rendering pipeline to build. Submit one job, and get back a post-ready MP4: video in, video out.
The subtitle API automates high-volume workflows. Caption ad creative, batch-style YouTube uploads, or generate scroll-stopping subs for short-form social cuts. It features auto language detection. You will also have optional SRT input to skip transcription. And async job model with status polling. Get API access on fal.ai.
How to use the subtitle API:
Step 1
Provide a video URL
Submit your video via URL: upload to FAL storage or use a presigned link from your own bucket. The subtitle API accepts standard video formats (MP4, MOV, WebM). You can optionally include srtContent to skip transcription if you already have captions for the video.
Step 2
Apply a style preset
Choose from VEED's library of subtitle presets. You can also use custom styling, such as your own fonts or colors. The API auto-transcribes the video, auto-detects the language, and applies your chosen preset to the timed captions, formatted and ready to render.
Step 3
Poll for the styled video
The subtitle API returns a job ID. Poll the status endpoint until processing completes. The final response is an MP4 with subtitles burned in: formatted, styled, and ready to publish to social, YouTube, or wherever your video lives.

End-to-end subtitle generation in one API call
Most subtitle APIs stop at the transcript. Pure speech-to-text services give you accurate text out, but getting from a transcript to a styled, burned-in video means building five more layers yourself: timestamp alignment, line break logic, visual styling, frame rendering, and output formatting. VEED's automatic subtitle generation API handles the full chain in a single call. Submit a video, get back a styled MP4. Skip the work of stitching together a transcription API, a styling layer, and a render pipeline, and ship a subtitle feature in days instead of weeks.
Battle-tested subtitle styles, ready out of the box
Pull from VEED's existing preset library, the same caption styles powering subtitle workflows in the VEED app across millions of videos. Each preset is tuned for readability across vertical, horizontal, and square aspect ratios, with font sizes, line spacing, and contrast levels chosen for social-first viewing on mute. Presets cover use cases from talking-head content to UGC ad creative to short-form social cuts. Pick the preset that fits your video and platform, and the subtitle generator API returns post-ready, on-brand captions every time, no design work or styling iteration required.
Built for high-volume, async video pipelines
The video subtitle API uses an async job model, so high-volume workflows don't block your application. Submit a job through FAL, get a job ID back in milliseconds, and poll the status endpoint until processing completes. The API auto-detects the input language, accepts an optional srtContent parameter to override transcription, and processes any aspect ratio without extra configuration. Pricing is duration-based and billed per minute through FAL, with predictable costs at scale and no seats or subscription tiers to manage. Submit jobs in parallel to caption a backlog of long-form content, batch-process daily YouTube uploads, or push live recordings through the API the moment they wrap.
