Why your photo produced a bad Tiny Desk AI clip
When a clip comes back uncanny, the upload is usually the reason. The model is being asked to keep a face it can barely see, or to swap a face that is not the only one in the frame. These are the uploads that fail, and the replacements that work.
The model can only keep what it can see
Your photo is the only source of identity in the render. Every pixel of resolution and every degree of angle you give it is detail the model can carry across 11 or 14 seconds of motion. A small face in a wide shot gives it almost nothing to work with, and the result drifts into a generic person.
The uploads that fail most often
A cropped head or a face turned to the side: profile angles lose half the features. Sunglasses, a mask or a hand across the face: the model has no eyes to keep. A group photo: the extra faces are ignored, and every face is smaller for it. A wide shot with a tiny subject: the same problem, without the extra people. Heavy beauty filters and screenshot-of-a-story cropping: smoothed and resampled detail reads as a different person.
Low light is its own failure: noise is not detail, and a dark face gives the render nothing to reconstruct.
What to send instead
One person, front-facing, head and shoulders or full body, evenly lit, in focus, JPG or PNG or WebP under 10 MB. If the template walks into frame, a full-body shot helps; otherwise head and shoulders is enough.
One face is the whole requirement. There is no second slot to fill.
When the photo is fine and the template is the problem
Templates differ in how much the lead moves. Five Strangers pans across a room; The Original Desk ends on a close-up with a sax flourish. A photo with a lot of headroom or an unusual crop can survive one and look wrong in the other. If a good portrait produced a strange clip, try a second template before re-shooting the photo.
Retrying costs nothing when a render fails
A render that errors out returns its credits automatically. A render that completes and simply does not look like you is a finished file, so the credit is spent — which is why the upload is worth getting right before you submit rather than after.
