What is Captioner?
Creating video content often involves the time-consuming task of adding subtitles. You need accuracy for accessibility and engagement, but manual transcription or wrestling with clunky tools can drain hours from your workflow. Captioner is designed to give you back that time, providing highly accurate, AI-powered subtitles directly within your browser. Upload your video, and let Captioner handle the heavy lifting of transcription and timing, so you can focus on your message.
Key Features
🎯 Achieve High Accuracy Transcription: Captioner utilizes an optimized version of the Whisper AI model, focusing specifically on transcription quality for video. This means fewer errors to correct, saving you significant editing time. It supports transcription in over 98 languages.
⏱️ Get Precise Timestamps: Forget subtitles that appear too early or late. Captioner employs extra processing to ensure timestamps align closely with the speech in your video, even offering word-level timestamps for fine-grained adjustments when needed.
✍️ Enjoy a Smooth Editing Experience: Built by content creators, the Captioner editor is designed for intuitive use. Make corrections, adjust timing, and refine your subtitles directly in your browser without complex software.
📥 Import and Align Existing Transcripts: Already have a script or transcript? Upload it to Captioner, and the tool will automatically synchronize the text with your video's audio, similar to YouTube's auto-sync feature but with enhanced precision.
🌐 Export in Multiple Formats or Burn-in: Download your subtitles in popular formats like SRT, VTT, or SBV, ready for upload to platforms like YouTube or use in editing software. Alternatively, choose a font style and export a new video file with the subtitles directly burned in.
🗣️ Translate Subtitles Easily: Reach a broader audience by translating your subtitles. Currently, translation from English to Mandarin Chinese is available with a single click on the Express plan, with more languages planned.
Use Cases
For the Busy YouTuber: You've just finished editing your latest video. Instead of spending hours typing out subtitles, you upload the video to Captioner. Within minutes, you receive an accurate transcription with precise timing. After a quick review in the editor, you export the SRT file and upload it directly to YouTube, making your content accessible and searchable faster.
For the Online Course Creator: You need clear, readable captions for your educational videos to ensure accessibility for all learners. Using Captioner, you generate subtitles, make minor adjustments for clarity in the browser editor, select a clean font style, and export the video with subtitles burned in, ensuring a consistent viewing experience across all platforms.
For the Marketing Team: Your company is launching a new product video targeting international markets. You use Captioner to generate accurate English subtitles first. Then, using the translation feature (currently English to Mandarin Chinese on Express), you create a version for another key market, expanding your reach with minimal extra effort.
Conclusion
Captioner is built to remove the friction from video subtitling. By prioritizing accuracy, providing precise timing, and offering a user-friendly editing experience, it allows you to produce accessible, professional-looking videos more efficiently.
