Test it

Using "remotion-captions". I have a local SRT file and need captions in my composition.

Expected outcome:

  • Place the SRT file in the public folder.
  • Load it with staticFile and fetch it during rendering.
  • Parse the text with parseSrt, then pass the captions to Remotion caption utilities.

Using "remotion-captions". I want a TikTok-style caption display.

Expected outcome:

  • Group captions into pages with createTikTokStyleCaptions.
  • Render each page in a timed Sequence.
  • Use token timestamps to color the word currently being spoken.

Security Audit

v1 • 7/19/2026 Open versioned report

All 11 static detections are false positives or benign documentation examples. The fetch calls load local Remotion assets, the command references are Markdown or comments, and the file write saves generated captions to a fixed local filename. No prompt injection, credential access, or data-exfiltration intent was found.

What You Can Build

Add captions to a social video

Create timed caption pages and highlight the active word in a Remotion composition.

Reuse an existing subtitle file

Load a local SRT file, parse it, and use the captions with Remotion utilities.

Transcribe recorded narration

Generate caption JSON from an audio file with the Remotion Whisper.cpp integration.

Try These Prompts

Start with caption JSON 
Show me how to represent these timed subtitles as Remotion Caption JSON: Hello from 0 to 900 milliseconds, then world from 900 to 1500 milliseconds.
Import an SRT file 
Help me load a local subtitles.srt file from the Remotion public folder and parse it with @remotion/captions.
Render caption pages 
Create a Remotion component that groups Caption data into pages and renders each page at the correct time.
Build a transcription workflow 
Plan a local Remotion workflow that transcribes one audio clip at a time, saves Caption JSON files, and renders synchronized captions.

Best Practices

  • Store each clip's captions in a separate local JSON file.
  • Keep spaces in caption token text and use whiteSpace: pre when rendering.
  • Test page timing at the composition frame rate before exporting a video.

Avoid

  • Do not use caption text without timing data for synchronized rendering.
  • Do not remove leading spaces from tokenized captions when word spacing matters.
  • Do not assume one transcription model produces accurate captions for every audio source.

Frequently Asked Questions

What caption format does this skill use?
It uses the Remotion Caption format with text, start time, end time, timestamp, and confidence fields.
Can I use an existing SRT file?
Yes. The skill shows how to fetch a local SRT asset and parse it with parseSrt.
Can the skill transcribe audio?
It explains how to use the Remotion Whisper.cpp integration to transcribe audio and convert the result to captions.
Where should I save caption files?
Save local caption JSON or SRT assets where your Remotion project can serve them as static files.
Does it support word highlighting?
Yes. It shows how to use caption token timing to identify and style the active word.
Does it install dependencies automatically?
No. It provides installation commands and implementation guidance, but you run commands in your own project.
