Current release: VidSync 1.821
VidSync 1.821 runs on macOS 14.6 (Sonoma) or later, on both Apple Silicon and Intel Macs. It brings much better automatic plumbline detection, background video export with a progress queue, automatic re-attachment of video files when a project folder moves, and a rebuilt data export. See the full release notes.
This version is signed and notarized by Apple, so it opens normally. Unzip it and move it to your Applications folder; the right-click workaround older versions needed is no longer necessary.
Newest version: VidSync 1.821
Previous release, for MacOS 12 (Monterey) and later
I’ve received many requests for a version of VidSync that works with the latest MacOS, including the Apple’s new proprietary M1, M2, M3, … processors. As of 2025 it is still working well on MacOS 15.2 Sequoia, and that’s unlikely to change with upcoming OS versions. I got all important features working and upgraded to the new architecture (while maintaining backward compatibility with Intel-based Macs), but a few minor glitches remain.
The “portraits” feature, which allows you to save internal screenshots of things (like individual fish) linked to objects in the object-event measurement hierarchy, is currently disabled because Apple really ripped out the whole infrastructure I had used to build that feature. However, I’m not aware of anyone besides myself ever needing or using that specific feature.
I’m releasing this imperfect version because it should still work for 99% of applications.
Previous version: VidSync 1.721
Outdated release
This version requires OS X 10.9 or later, tested up to 10.15. Apple’s OS changes eventually broke it. If you’re on older OS versions on an Intel-based Mac, it might still work fine. It did have the portraits feature working.
Older, complete version: VidSync 1.661
Manually unzip and move to Applications. You may need to right-click and choose “Open” to override Apple’s security warnings.
If you need an even earlier version than this for some unusual reason, contact me.
