Wan 2.1 for tutorial slide rule work
Wan 2.1 is the first generation of the family, best known for motion consistency. This page is the 5-second image to video route for a slide rule, in a tutorial treatment.
What to set
- Duration: 5 seconds. Longer runs cost more credits, and the credit cost is shown next to the form before you submit, so the price is known before anything runs.
- Task: image to video. Upload a still and the model animates it; the first frame is kept.
- Aspect: 4:3 - the older broadcast ratio, still common in archival footage.
- Style: tutorial. Put the style words first in the prompt - they weigh more than modifiers placed at the end.
A prompt that works for a slide rule
tutorial, a slide rule in motion, natural light, shallow depth of field, 5-second shot, no text
Treat the first render as a test rather than a final asset: watch the motion, then change one thing at a time. The live controls on the page are the source of truth for what the model accepts, not this text.
