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](/guide/export-and-compositing#mask-export) 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](/guide/credits-plans-modes#the-queue) 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](/guide/prompting-guide). 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. | *** > **🆘 Still stuck?** Use the in-app **Debug Info** panel (**Ctrl + Shift + D**) to copy diagnostic info and share it with support.
