Choose a frame where the change is easy to judge.
Runway’s Single edit workflow lets you preview an edited keyframe before applying it to the video. Select a frame that clearly shows the target, then use a short instruction with an action and a specific visual change. These original prompt examples give you a place to start.
A warmer interior
Start with
A room shot with visible windows, furniture and a steady camera move.
Try this instruction
Relight the room with warm late-afternoon sunlight from the window.
Check in the result
Follow window edges, light direction and furniture shadows as the camera moves. Decide whether the changed lighting stays coherent across the shot.
One product change
Start with
A clear tabletop shot where the object remains visible throughout.
Try this instruction
Replace the white vase with a cobalt-blue ceramic vase.
Check in the result
Watch the new object’s outline, reflections and contact with the table, especially when a hand or another object passes in front of it.
A different outdoor mood
Start with
A street or garden clip with a clearly visible background.
Try this instruction
Change the scene to a misty early morning with soft cool light.
Check in the result
Compare foreground edges and the strength of the mist over time. Keep attention on whether the subject remains legible in the new atmosphere.
REVIEW THE WHOLE SHOT
A good keyframe is the beginning of the check.
Confirm the intended edit
Compare the edited keyframe with the source. Verify the requested object, light or setting before applying the change to the selected range.
Follow movement and occlusion
Inspect moments when the camera turns or a subject passes in front of the edited area. These moments make changes in edges and shape easier to notice.
Check what carries through
Watch the final frame and play the whole shot again. Look for the same visual direction and continuous motion from beginning to end.
