| What you see | What to check |
| --- | --- |
| A node has no output | An empty source needs text/media or its own generation action |
| Generate is unavailable | Required references are empty/uploading/pending, a prompt or voice is missing, or settings exceed model limits |
| Connecting a source did not start the next node | Generate downstream explicitly; connection alone passes input |
| A connection is rejected | Media kind/mode is incompatible, an input is already full, or the connection would create a loop |
| New model rejects my references | Check reference support/counts and settings for that model |
| Image description is empty | Generate Text's analysis; attaching the image alone does not describe it |
| Extractor results are stale | Re-analyze after changing the video and prepare the new references |
| Merge fails | Check codec, dimensions/orientation, audio compatibility and all required clips |
| Storyboard cannot be edited inline on a phone | Open its expanded editor |
