Open the image in its project context
Start from the character, outfit, location, object, or cut you are working on. Check which image is currently selected and what that image will guide.
For a character, look at the face, silhouette, outfit, and scale. For a location or object, check the shape and details the camera will need. A pleasing image is not necessarily a useful reference for the next shot.

Compare before replacing
Check the request
Review the prompt, references, and settings available for the selected model.
Generate a result
Review the estimate and submit the request. Wait for the result rather than sending the same request again.
Inspect at a useful size
Open promising results large enough to see the details that matter to the story.
Select the image to use
Confirm which result is selected. Keeping an image in history alone does not make it the active reference.
Choose the right kind of correction
Use drawing or masking when you need to mark a specific area for an available image-editing operation. If you want a different overall composition or prompt, return to generation with the appropriate reference and instructions.
Keep a result that already works. Changing a reference affects later requests; it does not repair every completed video that used the previous image.
