The drawer is closed. A chair is tucked beneath the desk, its back only a few centimetres from the drawer front. In the final frame, the drawer is fully open and the chair has not moved.
Both images work as stills. Together, they describe an action with no clear path.
I run the independent third-party MiniMax H3 site, which is not affiliated with MiniMax. This scene is hypothetical, but the planning problem is common to any clip built around two fixed frames: the beginning and ending may look right while the space between them does not.
Compare the positions before adding detail
Put the two frames side by side. Start with objects that should stay fixed, such as the desk legs and the floor. Then compare the drawer edge with the chair.
The drawer needs to move through the area in front of the desk. If the chair occupies that area in both frames, the layout needs to change. More description will not create the missing space.
This check is useful before working on lighting, surface detail, or the objects inside the drawer. Those additions may improve each image without solving the blocked movement.
Give the drawer a clear route
The simplest change is to pull the chair back in the opening frame. The drawer can then slide forward without another action. If the chair must remain beneath the desk, the drawer can open only partway. A third option is to show the chair moving first.
After generating the clip, pause near the middle and look at the gap between the two objects. Check whether the chair clears the drawer, whether the drawer stops in time, or whether their shapes begin to overlap. These are observations to make during review, since the actual result can vary.
Then watch the same section at normal speed. The drawer should not reach the chair before the path is clear.
