Clapperboard Sync

Coming this fall: ClapperBoard Sync is a Mac app for turning image sequences — scanned books, musical scores, or stop-motion frames — into narrated or scored video. It auto-syncs page turns to your audio track, with precision cropping and grid-detection tools, then exports to video from an intuitive timeline editor.

Mac iPad (planned)

Sync text to audio

Sync musical scores to audio recordings

Efficiently segment score pages into page-per-system (Clapperboard autodetects systems), then quickly sync to a recorded performance.

Stop Motion

Quickly turn the pages of a PDF document, or a collection of still images into a stop motion video with soundtrack.

🎬

Frequently asked questions

When does Clapperboard Sync launch?

We expect Clapperboard Sync to launch this fall — this page will be updated with a download link as soon as it's available.

Which devices will it run on?

Clapperboard Sync launches on Mac. An iPad version is planned and slated to arrive later. It will not be a separate purchase: buying or subscribing on one device covers both.

How will pricing work?

You can try Clapperboard Sync without paying: until you buy or subscribe, exports are watermarked and capped at 720p. To lift those limits, choose one of two options. A one-time purchase unlocks the current major version for good, including all its minor updates, and owners get future major versions at a discount. A monthly or annual subscription includes every future major version and starts with a 7-day free trial. Exact pricing will be announced closer to launch.
