Home/Snapchat export overlay files (main + overlay)
Captions and stickers
Snapchat Memories overlay files, baked back on
Snapchat still does not flatten overlays into the main file. If you only import -main, every caption is gone. Overlay bake is the Pro path; the scanner always counts how many overlay pairs you have.
What the files look like
2024-10-31_UUID-main.jpg is the camera frame. 2024-10-31_UUID-overlay.png is stickers, location filters, and type on a transparent canvas. Video overlays sometimes arrive as overlay.zip containing that PNG.
How we composite
Photos: canvas draw of main, then overlay, export JPEG 0.92, then EXIF. Videos: ffmpeg.wasm overlay filter when the browser can load it; otherwise the dated main file is still exported and the PNG is skipped rather than attached to the wrong clip.
