How do YouTube chapters work?

StintBox converts your lap markers into timestamped chapter markers in the video description. YouTube picks these up automatically.

What if my upload is interrupted?

StintBox uses YouTube's resumable upload protocol. If your connection drops, the upload resumes from where it left off.

Yes — you can choose Public, Unlisted, or Private visibility in the publish wizard.

StintBox exports up to 4K (3840x2160) at 60fps. YouTube processes the video after upload.

Publish overlay videos directly to YouTube with chapters

StintBox uploads your finished overlay video directly to YouTube. Lap markers become YouTube chapters automatically, so viewers can jump to any lap.

Import your video and telemetry, add widgets, and preview your overlay.

StintBox pre-fills a title and description with session stats. Edit as needed.

Hit publish. Lap markers are injected as YouTube chapters. Resumable upload handles any interruptions.
