Track to New Null is a single-button panel for After Effects. Press it once, and the panel bakes tracking data onto a brand-new Null layer, then parents that null to the source layer. It reads tracking from both AE Motion Tracker and Mocha AE.
Version 1.1.0 adds a 'Parent to layer' option that is on by default. Turning it off creates a free null with no parent instead. The same release also fixed a crash that occurred with long Mocha AE tracks.
The panel runs on After Effects 24.0 and later, covering the 2024, 2025 and 2026 releases, on both Windows and macOS. On aescripts it currently sits at popularity rank 133, and a demo video is available for a closer look.
