v1.1.7 Released: Time Jump & Faster Loading!

Evolve Your Racing Skills

SyncA (pronounced "Shinka", meaning Evolution) is a powerful, free multi-video comparison tool. Synchronize up to 10 videos frame-by-frame, automatically calculate segment times, and compare your driving lines with rivals.

Windows 10/11 (64bit) Only
The application automatically displays in Japanese when used in a Japanese OS environment, and switches to English for all other environments.
Currently Windows only, but I'm focused on providing the best desktop analysis experience!

Directly load YouTube URLs alongside local videos. Synchronize and compare them seamlessly. Now supports start time parameters (e.g., ?t=1m30s).
* Will magically stop working if YouTube sneezes and changes their specs. Enjoy it while it lasts! ¯\_(ツ)_/¯

Sync multiple videos frame-by-frame. Remove unwanted clips easily with auto-arranging dynamic layouts.

Smart Lap Calc

Calculate segment times with color-coded gaps. Click table headers to change the reference lap on the fly.

Advanced Control & Export

Manual time jump, custom video names, individual mute controls, optimized multi-screen UI, and export to Excel (.xlsx) for deep review.
