A template is not just a preset style. It is a reference performance that supplies movement, timing, and camera behavior for every generation.
Why a template beats a prompt
A text-only prompt has to invent the scene, motion, camera, and identity at the same time. A video template already contains those decisions, so the model can focus on the character replacement.
What stays the same
The reference video keeps the freestyle motion, timing, background action, and overall camera language. The upload changes the appearance of the main performer.
What can change
Clothing, hair, body proportions, and the exact final likeness can shift as the model interprets the portrait. A clear photo gives the model less to guess.
Rights and permissions
Before publishing a public template, the operator needs the rights required for the source video, music, and performer likeness. Users also need permission to upload the people shown in their photos.
