WhisperX generates word-level timestamps so each word highlights exactly when it's spoken.
Bold Bayon font, white text, black outline. The current word turns cyan; everything else stays white.
Black rounded badge for the first 4 seconds. Font auto-sizes to fill the frame.
Two pill badges pop in for the last 4 seconds: "Follow for more" + your custom channel tagline.
Add a Claude API key (~$0.003/video) to auto-generate titles, descriptions, and tags.
Free YouTube Data API integration uploads your finished video as a private draft.
Most video captioning tools are cloud-based, charge monthly subscriptions, and require you to upload your files to someone else's server. Cody's Quantum Captioning is different — it runs entirely on your own Windows computer using WhisperX for AI transcription, so your content never leaves your machine.
Whether you're repurposing podcast episodes into TikTok clips, YouTube Shorts, or Instagram Reels, this tool handles the tedious captioning work so you can focus on creating great content.
Is this really free? What's the catch?
Yes, it's genuinely free — no trial period, no feature limits, no watermarks. Cody built this tool to solve his own podcast clip workflow and decided to share it. You'll be asked for your email so he can occasionally send useful podcast production tips, but you can unsubscribe anytime.
What are the system requirements?
Windows 10 or 11 with Python 3.10+. An NVIDIA GPU is recommended for faster transcription via CUDA acceleration, but the tool works on CPU-only machines too (just slower). The installer handles all dependencies automatically.
Does my video get uploaded to the cloud?
No. Everything runs locally on your computer. Your video files, transcriptions, and finished output never leave your machine. The only optional network call is the YouTube upload feature, which you control.
What caption style does it use?
Bold Bayon font with white text and black outline. The current spoken word highlights in cyan while everything else stays white — a karaoke-style effect that keeps viewers reading along. It's designed for vertical (9:16) video but works with any aspect ratio.
Can I customize the captions, title card, or CTA?
Yes. The configuration file lets you set your channel name, custom tagline for the CTA overlay, title text, and more. The tool generates everything from your settings each time you run it.
