How does a still photo become a shaking head animation?
A shaking head animation is made by giving an AI video model one photo and a fixed shot list, so it redraws your subject squinting, snapping its eyes open and shaking its head for 10 seconds. AI Shaking Head builds the shot list in. Unofficial: not affiliated with TikTok, CapCut, ByteDance or the original creator. Animate a photo.
How does the animation get made?
You upload a photo and pick a template. The site sends the photo and the template's instructions to a video model from ByteDance. The model generates new frames in which your subject performs the loop. The original sound is then added to the finished file. Nothing is cut out and moved like a paper doll, which is what makes the open-eyed snap possible. For why writing those instructions yourself is hard, see the prompt page.
What moves and what stays?
| Moves | Stays from your photo |
|---|---|
| Eyelids: shut, then wide open | Face shape and proportions |
| Head: slow sway, then a quick side-to-side shake | Fur or hair colour and markings |
| Mouth: closed grin, then open, tongue tip out on a pet | Clothing, collar or blanket |
| Ears, cheeks, whiskers or hair react to the shake | The overall scene and light |
The angle matters: a front-facing photo gives the model the most to work with. The tutorial lists the photo tips.
What is the beat sheet?
Measured from the original clip, each loop runs about 3.6 seconds and the clip repeats it three times.
| Time | Beat | What happens |
|---|---|---|
| 0.0–1.2s | Smug squint | Eyes squeezed shut, a cheeky closed-mouth grin, the head sways slowly left and right. |
| 1.2–1.5s | Snap | The eyes pop wide open in one frame and the head lifts. |
| 1.5–3.2s | Wide-eyed shake | Round staring eyes, the mouth opens (tongue out on a pet, a goofy grin on a person) and the head shakes quickly side to side. |
| 3.2–3.6s | Back to the squint | The eyes close again and the smug grin returns. |
| 3.6–10.0s | Loop twice more | The same squint, snap and shake repeat twice, in time with the original sound. |
The same timing is used on every template, so a calf, a dog and a selfie all snap at the same moment as the cat. Read how the loop started on the trend page, why it is funny on the funny shaking head page, or try the Smug Cat template.
