Two prompts, not one.
Image models draw; video models move. Asking one tool to do both is why animated stickers used to come out as nine stiff keyframes. Get the sheet first, then hand it to something that actually understands time.
Pick eight emotions — the first prompt gets you a 4×2 sticker sheet, the second animates all eight cells at once. Paste into ChatGPT or Nano Banana with a photo, run the result through Veo, Sora or Kling, then bring the clip back to slice into an animated pack — clip import lands in GridSticker soon, iOS first.

Image models draw; video models move. Asking one tool to do both is why animated stickers used to come out as nine stiff keyframes. Get the sheet first, then hand it to something that actually understands time.
The whole 4×2 sheet goes into the video model as a single image. One generation animates all eight stickers simultaneously — each cell acting out its own emotion, in place.
Video models want to pan and push in. The prompt forbids it four different ways, because one drift ruins all eight cells at once — the grid has to stay pinned for the slice to work.
Paste into ChatGPT or Nano Banana with your photo. Set the aspect ratio to 16:9.
Feed the sheet you just got back into a video model (Veo, Sora, Kling) as the input image, with this prompt. Set the clip length to 3–5 seconds.
The highest-risk failure, and the one to expect. Video models are trained to move the camera and a locked grid fights that instinct. Re-run the generation first; models vary run to run. If it keeps happening, try a different video model — some hold a static frame far better than others.
The motion was too big for the white padding around that cell. Edit that emotion's cell in the builder to something smaller, or re-run — amplitude varies between generations.
The model treated the sheet as a scene to reframe rather than a canvas to animate. Re-run. The prompt already states this four different ways, so a persistent failure usually means that model can't do it.
The last frame didn't return to the first. Slice it anyway and trim the tail frames in GridSticker's Animation tab — a couple of frames off the end usually seals it.
Regenerate prompt 1 before going anywhere near the video step. Text that moves and warps through the animation is unfixable afterwards.
Not in this flow — the grid is exactly 4×2, and the video prompt numbers all eight cells. Eight is also a valid LINE sticker pack size, which is why it's the number.
