then finish in your own Premiere timeline.
CHOOSE THE WORKFLOW
Export the tracked area as a white-on-black H.264 matte. Keep it alongside the source or hand the file to another editor. Align it with the same source, duration and timeline position to apply it again in Premiere.
Do both in an app built for mosaic work. The FANZA preset calculates a cell-size guide; click selection and tracking prepare your matte. Adjust the mosaic and export the finished video in Premiere.

QUESTIONS, ANSWERED
This workflow exports a white-on-black matte. Apply the mosaic and export the finished video in Premiere or another editor.
20px is a suggested cell size. Premiere uses horizontal and vertical block counts. Our 960×540 example uses 48×27 blocks. Recheck cell size and coverage when resolution or transforms change.
No. The preset calculates max(20px, long-side // 100) as a size aid. Check the current delivery rules and inspect the entire finished video yourself. The demo does not establish 4K tracking performance or a general speed or accuracy guarantee.
