Sharing
Adding your stats to a Reel or Story
Instagram's overlay track draws any image on black, so a saved overlay added there shows a black box around your stats. Use one of these instead.
In CapCut: tap Overlay, then Add overlay, and pick the overlay you saved with Save overlay. It stays see-through, and you can trim it to the part of the video you want.
In Instagram: tap Copy to Clipboard in Why Not's share sheet. Then in Instagram's editor tap Aa, hold, and tap Paste. Your stats go on as a see-through sticker you can drag and pinch to any size.
Or use Instagram's photo sticker: in the editor, open the sticker tray, tap the photo sticker and pick the overlay you saved.
