How to make an AI zombie trend video

1. Prepare two clear portraits and assign roles

Choose one adult per photograph, with a face large enough to inspect and both eyes visible. Even lighting and a simple background make it easier to judge identity. Avoid group shots, sunglasses and beauty filters that replace facial features.

In our generator, use the labeled photo slots for the person who turns and for you. In the free prompts below, reference A or image 1 is the human, and reference B or image 2 is the person who appears infected. When using those prompts in another tool, keep that role order and check that the tool supports both reference images.

• Confirm permission to use both portraits in the fictional story.
• Choose a portrait orientation for a vertical edit or a landscape orientation for a wider scene.
• Keep original files; avoid repeatedly compressing a screenshot of a photograph.

2. Write a short shot plan before generating

Write the full action order before adding atmosphere: standoff, raised pistol, recognition, lowered pistol, open empty arms, a short rush, embrace, then a hard cut to an earlier memory. Keep crowds and elaborate camera moves out so you can judge whether the essential actions actually happened.

The rainy-city partner plan uses six native clips: four four-second cold clips, a four-second beach-kiss clip and a five-second sunset clip, with the memory starting at 16 seconds. Other full-story selections use a 15-second cold clip and a ten-second memory. H3 is never asked for 25 seconds in one call. Four gentle variants still target ten seconds and omit the gun and rush. Planned timing and actions need output inspection.

3. Generate one scene at a time when continuity is difficult

For the dark scene, make the recognition and decision to lower the gun legible before the approach. Keep the infected appearance non-graphic and the distance short. Inspect the result before moving on: are the roles correct, is the gun out of view before both empty arms open, and does the rush end in an embrace?

For the memory, describe the same framing and the same embrace in a brighter setting before the infection, with B healthy. Make it explicit that this is a flashback, not a cure. If your selected tool supports a starting frame or pose reference, use an appropriate frame from the first clip. Only use that control when it is available; naming a reference in text does not create a missing model capability.

You can also try one combined prompt when the model supports the references and duration you need. Compare the result with the simpler two-clip workflow. A coherent short sequence is more useful than a longer output with swapped identities or an unreadable ending.

4. Make the match cut in your editor

Place the dark clip before the warm clip on the timeline. Find the last clean frame where the embrace is established, then find a matching pose at the start of the warm clip. Trim the first clip and move the second against it. Watch the cut without sound before adding any effects.

If the people jump across the frame, adjust a modest crop or choose a better matching moment. Keep the aspect ratio consistent. Avoid stretching one clip to fit another. A slight timing adjustment can help, but excessive slow motion may make generated hands and facial changes more obvious.

Hold the warm ending for a beat. The viewer should have time to see that the same people are safe together. You can finish on a smile or a still embrace without adding a second transition.

5. Add sound, captions and a readable export

First listen to any audio the model actually produced. Some models or modes produce silent video. If you add ambience, carry a quiet sound across the cut or let the sound change with the scene. Do not describe a silent output as a video with built-in sound.

Use a short caption only if it adds information the pictures cannot carry. Keep it away from faces and from the area a social platform will cover with controls. Export with the orientation of your source clips and inspect the final file on a phone as well as in the editor.

6. Check the story before sharing it

Review the exported file from beginning to end. Look at the faces before, during and after the embrace; identity drift often becomes obvious at the transition. Listen for unexpected voices or abrupt sound changes. Check that the video plays after download, not just inside the editor.

If the story fails, change the smallest thing that addresses the problem. For swapped roles, clarify A and B and their screen positions. For distorted hands, simplify the movement. For a weak ending, make the warm scene longer in the edit. Repeating a more elaborate version of the same prompt can add new failure points.

• Both people remain in the intended roles.
• For the full story: the raised gun, recognition, lowered gun, open arms and rush are all visible in that order.
• The embrace is readable and the cut does not hide a face swap.
• The final file plays, and any soundtrack is suitable for your intended use.
• The caption and disclosure make the AI-generated, fictional nature clear.
