Create a new five-second shot connecting the two supplied pictures. Start from the first picture and arrive at the second selected picture, preserving the adult headset wearer, clothing, stairwell and camera direction. Use a small continuous door-opening movement. Use these two selected pictures as the new shot's starting and ending frames.

He knew this door led downstairs. He opened it and died below. Footage shows him leave a safety marker, then curve towards the stairwell without visibly turning. Tracking was normal. The new build promised to steer him to safety. Why did it steer him here?

About

First and last frame AI video gives a shot two visual anchors. Upload the opening image and the ending image, then describe how the subject and camera move from one to the other. Related compositions, lighting and subject details make the intended transition easier to explain. Keep the journey focused on a clear action, choose a supported model and duration, then check the motion throughout the clip. A written ending is useful direction, but it does not replace an uploaded final frame.

Questions

What are the required inputs?

Upload one image as the start frame and another as the end frame, then describe the transition. A reference image or a written ending is not a substitute for the required end-frame input.

How do I prepare the two images?

Use compatible crops and keep identifying subject details consistent unless their change is intentional. Explain shifts in position, viewpoint, light or setting so the requested movement is clear.

Which model should I use?

Choose based on the shot. Seedance 2.5 supports up to 30 seconds; the other current models stop at 15. Seedance models have an audio switch, while MiniMax H3 and H3 Max include audio. Resolution and tier choices differ too.

Does this guarantee an exact transition?

Review the whole result for subject changes, unwanted cuts and moving geometry. Supplied endpoints guide the beginning and ending; they do not determine every intermediate frame.

Is this different from reference to video?

Yes. Endpoint images supply the intended opening and ending. Reference images guide a new scene without serving as those required endpoints.
