AI Video for Beginners, Part 3: Edit Your First Short Film
Arrange three simple shots, add a readable caption and suitable sound, then check the exported video. Finish your first AI short without elaborate transitions.
You have one usable shot. Now let’s turn it into a finished video. If you still need footage, return to Part 2. Today’s goal is a complete short, not a surprise in every second.
Add two simple shots
Photograph the café entrance and a tabletop under similar lighting. Generate short clips using the previous lesson’s method, or film them directly with your phone. Not every shot needs to be AI-generated.
Use this order:
| Order | Shot | Purpose |
|---|---|---|
| 1 | Entrance, locked-off camera | Establish the location |
| 2 | Coffee by the window, slow push-in | Draw attention to the subject |
| 3 | Tabletop detail, locked-off camera | Leave a little room for the ending |
Use about three or four seconds per shot, for a short lasting roughly ten to fifteen seconds. This is an exercise, not a rule for every video.
Edit with straight cuts first
In CapCut, Jianying or another editor, create a 9:16 project and place the three clips in order. Trim any waiting at the start and unstable frames at the end. Leave transitions off for now.
If a cut feels abrupt, check whether the brightness changes sharply or the subject jumps across the frame. Fix the mismatch before trying to cover it with an effect.
One caption is enough: “Before opening, a coffee for yourself.” Make it readable on a phone and keep it away from areas near the bottom and right edge where platform controls often sit.
Keep the sound gentle
Use music you’re licensed to use, or ambient sound you recorded yourself. Mute model-generated audio if it contains distracting noise. Your first short doesn’t need a voice-over.
Listen once with headphones and once through your phone speaker. A readable caption and comfortable volume matter more than a trending soundtrack.
Check the exported file
Export in vertical 1080p if your editor supports it. A higher export resolution won’t repair blurry source footage.
Open the exported file and check for black borders, obscured captions, distorted objects and uneven volume. Follow the publishing platform’s rules for labeling AI-generated or synthetic content. Don’t present generated shots as footage recorded on location.
Keep three things: the first frames, the prompts and the finished video. They’ll make revisions much easier.
You’ve now worked through preparation, generation, quality checks and editing. When you later try people or products, you’ll have a clearer idea of where things go wrong. Revisit any step through the beginner’s guide.
