Before Choosing a Video Model, Define the Job
Three fictional tasks are sitting on a project board:
- Animate a habit-tracking screen for eight seconds
- Make a coding-event teaser with music
- Show a desk lamp in three rooms
Someone leaves the same comment on all three:
Use the newest model.
The app screen starts from one illustration and needs no sound. The teaser needs several actions and verified event text. The lamp concept uses multiple references and scene changes.
All three involve video, but each one needs a different setup.
Write the Brief First
Before opening a generator, record six things:
Purpose:
Length:
Format:
Source material:
Sound plan:
Details that must stay accurate:
For the fictional habit-tracking app:
Purpose: Internal motion draft
Length: 8–10 seconds
Format: Vertical
Source material: One original calendar illustration
Sound plan: Add later
Must stay accurate: Calendar layout and final weekly view
The brief points to a short, image-led setup. Dialogue, a long timeline and multiple references are unnecessary.
Compare the Job, Not the Model Number
Ask a few practical questions:
| Question | What it decides |
|---|---|
| Are we starting from text, one image or several files? | Input method |
| How many seconds does the idea need? | Duration |
| Is sound generated, supplied or added later? | Audio workflow |
| Is this an internal draft or a public asset? | Output needs |
| Which details must remain accurate? | Review priorities |
| Where will captions and precise cuts be added? | Editing plan |
There is no need to rank every model. Rule out the options that do not fit the brief.
Treat the Model Page as a Menu
JXP’s Seedance AI Video Generator page currently compares several Seedance versions by inputs, reference support, sound, duration and resolution.
It is more useful as a menu than a leaderboard.
A short app-screen animation may only need one image and a simple sequence. A sound-led teaser may need generated audio or an eligible audio reference. A longer scene may need more source files.
These differences help with planning. They do not prove that one version produces better results than another. Output can vary with the prompt, references and selected settings.
Check the chosen generator before starting. Available controls, costs and usage rules can change.
Leave a Short Decision Note
A note in the issue tracker is enough:
## Video Setup
Purpose:
Create an 8–10 second internal motion draft for a fictional
habit-tracking app.
Use:
- One original calendar illustration
- Vertical format
- Short image-led generation
Do not need:
- Dialogue
- Generated sound
- Multiple video references
Review:
- Calendar structure
- Plant position
- Final weekly view
Boundary:
Generated interface details are concept material, not approved
product features.
The Do not need section keeps the task focused. If sound will be added later, there is little reason to generate it now. If only one image matters, adding more references may create extra decisions without helping the scene.
Match the Setup to the Task
The three fictional jobs can be reduced to a simple table:
| Task | Main needs | Main review point |
|---|---|---|
| App screen | One illustration, short sequence, no sound | Does the calendar remain readable? |
| Event teaser | Several actions and sound direction | Are the timing and actions clear? |
| Lamp concept | Multiple room references and scene changes | Does the lamp remain recognizable? |
The event date and registration link should be added and checked outside the generated clip. The lamp draft cannot prove brightness, dimensions, energy use or durability. The app animation should not be presented as a feature already available in a real product.
These are limits of the brief, not problems that a longer prompt can solve.
Record Why an Option Was Rejected
A few lines can prevent the same discussion from returning:
Reference-heavy setup:
Not selected. Only one source image is needed.
Generated-sound setup:
Not selected. Sound will be added later.
Short image-led setup:
Selected. It matches the input, length and review needs.
If the brief later gains a voice track or several references, the reason for reconsidering the setup is clear.
Check the Material Before Uploading
Before using a source file:
- Confirm that the relevant agreement allows external AI processing, derivative use and the intended publication or promotional reuse.
- Do not upload confidential files, unnecessary personal data, unlicensed music or recognizable voices without suitable authorization.
- Verify dates, prices, specifications and factual claims outside the generated video.
- Make the illustrative nature clear if viewers could mistake a synthetic scene for real footage, a working interface or a product test.
Review the complete output as well. A reference can guide the result, but it does not guarantee that every detail will remain unchanged.
Recheck When the Job Changes
Review the choice when the duration changes, new references arrive, sound is added or an internal draft becomes public.
“Use the newest model” is easy to write. A more useful rule is:
Pick the setup after the source files, length, sound plan and review points are clear.
