How to Make AI Videos (Step by Step)
Updated 2026-10-07
Making an AI video that people actually watch is less about one perfect prompt and more about a repeatable workflow. The videos that hold attention on TikTok, Reels and Shorts usually tell a tiny story: a character the viewer recognizes, a problem in the first second, a few escalating beats and an ending that makes them want the next part.
This guide walks through that workflow from a blank page to a posted vertical video. The steps work with any toolset, and we point out where StarKlip handles each part so you can see how the pieces fit together.
The AI video workflow, step by step
1. Pick one clear idea
Start with a single emotional situation you can explain in a sentence: a friend who doubts you, a family argument, a comeback after losing everything. Simple premises work because the viewer understands them instantly. If you need to explain the setup, the idea is too complicated for a short vertical video.
2. Create consistent characters
Decide who the story is about before writing scenes. Give each character a fixed look: face, hair, build, and one outfit you will repeat in every shot. In StarKlip you create characters once, build a stylized reference sheet for each, and reuse them across stories so the same person shows up in every scene.
3. Write a short multi-scene story
Break the idea into a handful of scenes. A reliable structure is hook, conflict, escalation, payoff and call to action. Each scene should describe what we see, who is in frame and the one line that is spoken. StarKlip’s Story Builder can write these scenes from your idea, or you can paste your own script and it keeps your wording.
4. Generate an image for each scene
Turn every scene into a still frame first. Images are faster and cheaper to iterate than video, so this is where you fix composition, expressions and character likeness. Regenerate any frame that looks off before moving on; a bad starting image almost always becomes a bad clip.
5. Turn the scenes into video
Animate each approved image into a short clip. StarKlip generates vertical 9:16 clips at several quality tiers, so you can test a scene cheaply and then render the final version at higher quality. For scenes that should flow directly into each other, use the option to continue from the previous scene’s last frame.
6. Add sound and music in an editor
Download your clips and assemble them in the video editor you already use, such as CapCut or the editor inside TikTok or Instagram. Add a trending sound or music bed, adjust the pacing, and add captions so the story works with the sound off.
7. Post to TikTok, Reels and Shorts
Export in vertical format and post. Write a caption that teases the conflict rather than summarizing it, and if the ending is a cliffhanger, tell viewers that part two is coming. Reuse the same characters in the follow-up so returning viewers recognize them.
Tips that make AI videos easier to watch
- Keep each clip around 5 seconds. Short clips stay coherent, and quick cuts suit the pace of vertical feeds. StarKlip scenes are generated at 5 seconds each.
- Start in the middle of the conflict. Skip establishing shots and introductions; open on the moment something goes wrong.
- Use one spoken line per scene. A single short line is easier to animate convincingly and easier for the viewer to follow.
- End on a cliffhanger. Leaving the final beat unresolved gives people a reason to follow for the next part.
- Repeat character details. Mention the same hair, outfit and accessories in every scene description so the look does not drift.
Common mistakes to avoid
The most common mistake is generating video before the still images are right. Every problem in the frame, from an extra person in the background to the wrong expression, carries into the clip and costs more to fix later.
The second is writing scenes that try to do too much. If one 5-second clip has to show a character entering a room, arguing, and storming out, the motion becomes rushed and confusing. Split it into separate scenes and let each one carry a single action.
Finally, avoid asking for written words inside the picture, like signs or text on a phone screen. Image models often render text incorrectly. Put any on-screen text in your editor as captions instead.
FAQ
How long should an AI video be?
For TikTok, Reels and Shorts, a story of roughly five to eight short scenes works well. At about 5 seconds per scene that gives you a 25 to 40 second video, long enough for a full arc without losing viewers.
Do I need to write prompts myself?
No. You can describe your idea and let the Story Builder write the scenes and prompts, or paste your own script and prompts if you prefer full control.
Can I add music inside StarKlip?
StarKlip lets you choose audio on or off for scene clips. For music, trending sounds and captions, use a video editor or the editing tools built into the platform you post on.
What format should I export?
Vertical 9:16, which is the native format for TikTok, Instagram Reels and YouTube Shorts. StarKlip generates scenes in this format by default.
