What this prompt is for
Use this template for small periodic actions: a rotating object, a swaying ornament or a repeating abstract motion. A loop is a relationship between the last and first frames. Calling a clip “seamless” cannot repair a changed face, a drifting camera or a new object entering at the end.
Prepare your variables
| Variable | What to supply |
|---|---|
| SUBJECT | A stable object or character with an unambiguous silhouette. |
| CYCLE | One periodic motion with a defined direction and speed. |
| ENDPOINT | The pose, position and lighting state that must match the start. |
| CAMERA | Prefer locked framing; otherwise define a genuinely periodic path. |
| DURATION | A supported clip duration that can contain one full cycle. |
Full prompt template
Create one [DURATION]-second continuous loop of [SUBJECT] in [RATIO]. Motion: complete exactly one cycle of [PERIODIC ACTION] at a consistent pace. Begin from [START STATE] and return to the same pose, position, orientation and movement direction at the end. Camera: [LOCKED OR PERIODIC CAMERA]. Keep framing, focus and perspective stable across the join. Continuity: preserve subject geometry, texture, clothing and background layout. Lighting, exposure, shadows and atmospheric density must return to their initial state. Nothing should appear, disappear or accumulate during the cycle. Keep movement ongoing through the boundary rather than stopping for a final pose. Do not add an opening reveal, closing fade, camera cut or ending title. If start/end reference controls are available, use matching reference states. The result still requires endpoint inspection and a repeated-playback test in editing.
Negative instructions
Jump at the loop seam, pause at the endpoint, changing camera position, drifting subject scale, texture mutation, accumulating particles, exposure flicker, opening fade, closing fade, new objects, unplanned cuts.
Use a dedicated negative field only when the selected model supports one. Otherwise describe the desired stable behavior positively in the main prompt.
Filled example
A small paper planet floats over a fixed ivory plinth. Create a six-second 1:1 shot with a locked camera. The planet makes one smooth full turn about its vertical axis. Begin and end at the same orientation, with the same rotational speed continuing across the boundary. Keep the planet’s paper continents, plinth and soft green studio light unchanged. No drifting particles, text, fade or final pause. In editing, compare the start and end, choose the closest matching boundary and preview at least five repetitions.
Target result and acceptance check
A candidate cycle whose boundary can be inspected and refined. This template has not been validated as a guaranteed seamless output for any model. A deterministic rotation in a motion editor is often more reliable when exact repetition matters.
- Watch once at normal speed for the intended action.
- Inspect the beginning, middle and end for face, hands, objects and background changes.
- Compare with your reference and brief. Keep the prompt, settings and reference together so revisions can change one factor at a time.
If the first result fails
The camera slowly creeps
Regenerate with locked framing. Stabilizing later can crop the image and cannot repair changing perspective.
The final frame holds still
Remove “settle” and “end pose” instructions. Specify continuous velocity through the join.
Particles accumulate
Use a periodic flow or remove particles. A growing pile is not a repeating state.
A crossfade creates a double face
Avoid dissolving between mismatched faces. Choose a better seam or rebuild the action in an editor.
Frequently asked questions
Should I duplicate the first frame at the end?
A duplicate can create a one-frame pause. Choose a matching boundary and test the playback cadence rather than automatically adding a copy.
Can a camera orbit loop?
Yes if the path and perspective return to the same state, but generating unseen geometry makes continuity harder. Start with a locked camera.
Does a crossfade always fix the seam?
No. It can hide small light changes, but it can also create ghosting and doubled geometry.
