Defining Your Image and Video Needs Before You Generate: A Practical Workflow

Disclosure: this article was drafted with AI assistance and reviewed by me; PixelMind, the tool referenced below, is a product I built myself.

Some disappointing AI image and video results begin with an underspecified request. They are definition problems: the request was too vague for any tool to answer well. This workflow defines the request before generation so outputs can be compared against the same criteria.

Step 1: Write down four things before touching a tool

  • Subject — the one thing the image is about, in one sentence.
  • Composition — what is in front, what is in the background, where the eye should go.
  • Visual tone — photographic, illustrated, flat, moody, bright.
  • Use — where the output will live: a slide, a thumbnail, a print, a background.

Writing these four items down gives you explicit criteria for comparing outputs.

Step 2: Choose your input path

Two valid starting points:

  • Text only, when nothing visual exists yet and you want the tool to propose directions.
  • Text plus a reference image, when you have something partial — a sketch, a photo, a layout — and words alone cannot say "like this, but different."

When a tool supports both inputs, the pair gives the request more visual context.

Step 3: Pick the model by requirements, not by name

Models differ on dimensions that actually change your output: how long a generation takes, the resolution you can get, whether a video model supports audio, and what each generation costs in credits. Decide which of these is binding for your task. If your use needs vertical video with sound, that narrows the candidates at once; if iteration speed matters more for a still image, different candidates fit.

Step 4: Generate a small batch, then compare against your four notes

Generate 3–4 outputs, put them side by side, and score them against the four notes from step 1 — not against "do I like it." Note what changed between prompt versions. Keep a one-line log per generation; the log lets you compare prompt changes with output changes.

Step 5: Stop at "reviewable," not "perfect"

The goal of this workflow is a visual direction you can show to someone else and get a useful reaction. Refinement comes after alignment, not before. When the batch contains one option that matches your four notes, that is the moment to share it.


The tool in this workflow, PixelMind, follows this split: the /generate page for text and reference images, the /video page for text-to-video and image-to-video, and a comparison page that lists models across duration, resolution, audio support, and starting credits. Free accounts receive 25 daily credits, and paid plans start at $20/month.

If you try this, I'd like to know which step you skip — that's usually where the interesting design problems are.

Another disclosure note: PixelMind is my own product; free daily credits, the comparison page, and the input paths described above are all documented on the site itself.
