To reduce face distortion in a Popstar AI video, start with a clear, front-facing portrait under even light and keep the face unobstructed. The fixed motion template follows the same performance for each render, so improving the source image is a more useful first check than writing prompt text the interface does not accept.
| Symptom | Review first | Why |
|---|---|---|
| Features shift during the walk | Face angle and visibility | A direct, unobstructed view provides clearer source detail |
| Face looks soft | Sharpness and compression | Output resolution cannot recreate detail missing from the input |
| Face is unevenly lit | Shadows and backlight | Lighting can hide facial boundaries |
| Clip looks too small | Output tier | Resolution changes export size, not likeness or motion |
Correct the face angle
Use a nearly straight-on portrait. Popstar AI recommends avoiding angles beyond roughly 30 degrees. A strong profile hides part of the face and can make the likeness harder to maintain during the walk-in.
Remove visual obstructions
Keep the eyes, brow, jaw, and shoulders visible. Replace images with a hand over the face, a fringe covering the eyes, or accessories that hide facial boundaries. A heavy filter can also alter the features the template needs to represent.
Improve sharpness and lighting
Use a clear file with even lighting. Avoid backlighting, strong shadows, blur, and compression artifacts. Change one issue at a time when testing another portrait so you can identify which improvement made the result easier to recognize.
Before another render, inspect the image at its actual viewing size. The face should be large enough to distinguish its features. Prefer an unobstructed portrait over a strong filter, extreme expression, or face partly hidden by hair or a hand. Keep the head and shoulders in frame. These are practical selection criteria, not a guarantee that every moving frame will preserve identity.
Compare inputs systematically
If you have another suitable portrait, change one factor at a time: retain similar lighting but choose a more direct angle, or keep the angle and choose a sharper image. Avoid changing the portrait and resolution tier together, since that makes the difference hard to interpret. Watch the full 12-second clip; a thumbnail may not show how the face holds up during movement. The prepared template has no user-facing free-text prompt, so prompt changes are not a way to repair likeness.
Resolution is not a likeness control
The video is 12 seconds and 9:16. The 480P tier costs 45 credits, 720P costs 90, and 1080P costs 180. Higher resolution changes the output tier, but cannot reveal a face that was hidden or unclear in the input. Check current pricing before rendering.
Distortion or failed render?
If the clip completes but the face is unstable, try a better portrait. If no clip is delivered or a job stops, check the render status and credit balance, then contact Popstar AI support with the time and selected tier.
Choose the next step
The 480P tier (45 credits) is the least costly listed option if you want to assess the result before selecting a larger export. Higher tiers change output resolution, not source detail or likeness. Check current pricing before generating. If a clearer, more frontal image still produces an unstable face, note the render time, tier, and visible issue for support. No documented manual facial-repair control is available in this workflow.
