Video Smoke Matrix
This page records the live OAuth API verdicts progrok uses for the underdocumented Grok Imagine video surface. The canonical REST shape is preferred even when SDKs expose convenience fields.

|---|---|---|
| T2V | Passed | grok-imagine-video prompt-only generation returned status: done. |
| I2V URL/data/local file | Passed | CLI local files are encoded as data URIs and sent as image: {url}. |
| R2V URL/data/local file | Passed | reference_images works on the base model; max 7 refs, max 10s. |
Image file_id | Passed | Uploaded image IDs worked for I2V and R2V. |
