Troubleshoot editing, exports, and transparency
Separate editor-save issues, frame selection, export entitlement, transparent encoding, and target-engine rendering before deciding to regenerate.

Start with the source and saved recipe
Confirm the correct source video, selected range or output sequence, frame count/FPS, canvas, and target formats. In Advanced Editor, check Saved before export. An export already submitted uses its saved snapshot, not later edits.
For COMPOSITION_CONFLICT or Save failed, keep the editing page open and avoid concurrent edits in other tabs. Record important changes before reconciling the newer revision. Do not overwrite another version blindly or assume refreshing preserves unsaved work.
Format unavailable or export rejected
PAID_EXPORT_REQUIRED means a Studio/web request lacks current entitlement for the selected advanced format. It is different from INSUFFICIENT_CREDITS, which concerns the operation's quote. Public API/MCP exports follow the developer contract, while commercial-use rights still follow the applicable paid terms.
Check the selected formats and actual source requirements. Transparent video needs appropriate transparent processing and a transparent output canvas. Public API/MCP transparent export requires an Alpha Key source; it cannot fall back to arbitrary AI background removal.
Opaque background or unexpected key color
| Observation | Likely place to inspect |
|---|---|
| Raw generated video has green/magenta background | Expected Alpha Key intermediate; choose a transparent export |
| Downloaded MP4 is opaque | Format does not carry the intended Alpha |
| PNG is transparent, video looks black | Player/decoder/compositing support |
| Every format contains the same unwanted background | Source transparency, processing mode, or solid canvas |
| Thin halo or clipped detail | Source Alpha, key-color spill, scaling, and target material |
| Only some frames fail verification | Inspect those frames; do not infer quality from the first frame alone |
Keep a PNG baseline from the same export settings. See transparent formats and compatibility. A viewer's checkerboard setting and an encoded Alpha channel are not the same thing.
Wrong duration, frame order, or alignment
Compare expanded frame count and FPS. Repeated frames lengthen a sequence at a fixed FPS; Reverse affects the whole sequence. A loop flag does not make mismatched endpoint poses seamless.
Check whether a target engine imported the matching texture and metadata, preserved the frame order, and applied the intended pivot. Godot's scene offset and Cocos's script-embedded pivot need care when reusing only part of a pack.
Use the specific Unity, Godot, Unreal, or Cocos instructions.
Failed export with partial outputs
A job may fail after creating a source video or some assets. Inspect outputs and its error before retrying. Save useful existing files, distinguish partial delivery from complete success, and check actual credits.
If a retained video can support another export, you may not need another AI generation. New processing still needs a quote and any required approval. Do not promise a refund solely because the final status is failed.
Download fails or a source disappears
Refresh an expired signed link through authorized asset metadata. A real not-found can instead mean deletion, ownership mismatch, or a missing source object. Check storage and cleanup; deleting history and deleting files have different effects.
Report the task/request ID, format, error code, and whether matching PNGs display correctly through private support. Do not include raw signed URLs or credentials.
