Lesson 2 of 7
Two ways to start
7 min read
There are two ways to get a moving clip: type a description and let the tool dream up the whole thing, or hand it a picture you already have and just tell it how to move. Which should you reach for?
Starting from words
You already met the first way in the last lesson. You describe a scene — a paper boat drifting down a rain-filled gutter — and the tool invents everything: the boat, the colours, the light, where the camera sits. It's pure imagination, which is wonderful for exploring an idea. The catch is control: you don't get to decide the exact look, and run it again and you'll get a different boat.
Starting from words — text-to-video — gives you the most imagination and the least control over the precise look. Each run reinvents the scene.
Starting from a picture
The second way starts from something fixed. You give the tool a single still image — a photo you shot, or a picture you generated — and a short note on how it should move: slow zoom in, the boat drifts left. The tool keeps your image as the very first frame and only adds the motion. Everything you already got right in the picture stays exactly as it is.
Starting from a picture — image-to-video — locks the look: your image is frame one, and the tool only supplies the movement.
Which one, when
A simple rule. If you want to explore an idea fast and don't mind the exact details, start from words. If you have a specific look you must keep — your product, a particular character, a real photo — start from a picture. And there's a favourite combination: generate the perfect image first, then animate it.
This is where the last course pays off: make a still image exactly how you want it, then feed that image in as the first frame and describe the motion. You keep full control of the look and still get a moving clip.
The gist
- —Text-to-video starts from words — most imagination, least control; each run reinvents the look
- —Image-to-video starts from a still you provide — it keeps your picture as the first frame and only adds motion
- —Want a fast idea → words; need a specific look kept → a picture; a common combo is make the image first, then animate it
You've generated a great image of your product and you want a five-second clip where the camera slowly pushes in — same product, exactly the same look. Which approach fits?
