Common problems and their fixes, grouped by symptom.

Flicker
Identity drift
Mask issues
Face issues (Mago Character)
Render time issues
Prompt issues

Flicker

Symptom	Likely cause	Fix
Flicker at the start of a Style Transfer render	Weak stylized first frame	Use a cleaner, higher-contrast stylized first frame; keep Dynamic reference on.
Flicker throughout a long render	Chunking issue	Increase Context overlap. Ensure Dynamic reference is on.
Flicker in Mago Transform with depth ControlNet	Depth ambiguity in low-contrast scenes	Switch to SoftEdge ControlNet for the same shot.

Identity drift

Symptom	Likely cause	Fix
Character changes appearance across a long shot (Mago Character)	Pose strength too high or weak reference	Lower Pose strength. Use a more distinctive reference.
Character changes across a chunked render	Dynamic reference disabled or context size too large	Enable Dynamic reference. Reduce Context size to 100–120.
Closed-source character replacement drifts	Inherent to closed-source models	Switch to Mago Character for stricter identity. Use Elements (Kling 3.0 Motion Control) for multiple reference angles.

Mask issues

Symptom	Likely cause	Fix
Mask too tight, visible seams in render	Mask too conservative	Increase Expand by 5–10 px. Increase Blur.
Pixel shift in unmasked regions of an inpaint result	Compression in video models, not a bug	Download the mask. Composite externally for pixel-perfect preservation.
Full-range Mago Inpaint render fails with a frame-count error	Source video has a variable/odd frame rate; the mask and source video decode to different frame counts	Re-export the source at a fixed frame rate before uploading, or trim to a whole-second range. Contact support if it persists.

Face issues (Mago Character)

Symptom	Fix
Eyes appear closed / expression frozen	Increase Grow face mask to include more of the face region.
Eyebrows or forehead clipped	Increase Grow face mask.
Expression doesn’t match the source	Lower Face strength.
Face too stylized away from intended look	Raise Face strength.
Lighting doesn’t match the scene	Enable Relight. Increase the value if the correction is weak.

Render time issues

Symptom	Fix
Render taking many hours	Contact support — this is usually an error. Refunds are available.
Render time estimate keeps growing	Known issue. Wait for completion or contact support.
Renders queuing in Credits mode despite available credits	Likely GPU saturation. Wait, or switch to Relaxed mode for non-urgent work.

Prompt issues

Symptom	Fix
Mago model not changing the scene much	Verify the prompt is descriptive, not instruction-based. Make the description more specific.
Closed-source model changing too much	Add preservation directives: keep the character, composition, lighting, framing.
Nano Banana Pro confusing source and reference	Add explicit phrasing: “use the first image as the reference”.
Output looks generic	Use a stronger reference image. Be more specific in the prompt.
