Create a travel postcard with gently changing aurora bands

1. Task and boundary

Make a travel-postcard scene with gentle changes inside aurora bands already visible above a fixed mountain landscape.

The original bands ripple and change brightness locally. Simply sliding the entire sky sideways or rotating the stars does not create this result.

Use a modest variation of the existing bands and their starting colors.

2. Authorized first frame

Choose an authorized night landscape with recognizable aurora bands, a clear mountain ridge and several visible star points. Leave enough sky around the bands for a small local undulation.

3. Use the generator

Open the image-to-video generator, select your authorized first frame and paste the prompt. Review the available controls before submitting; this page does not upload or generate for you.

1. Select a source with distinct bands rather than a featureless colored sky.
2. Ask for small internal ripples and brightness variation, not a camera move.
3. Compare one ridge point, a few stars and the same band segments across the clip.

4. Prompt and timing

Keep a fixed view of the original mountains, stars and aurora bands. Let small sections of the same luminous bands gently rise and fall, with soft local changes in brightness passing along their existing shapes. Keep the mountains and star points stationary within this designed short shot. Preserve the original band group and main color range. End with those same bands still above the ridge. No whole-sky slide, star rotation, new celestial object, replacement landscape or text.

5. Inspect the output

Review the complete result, then pause at the listed events. Mark an obscured event not visible; the prompt itself is not evidence that it happened.

• The changing light remains part of the original recognizable band group.
• Local sections undulate or brighten without the entire sky sliding together.
• The chosen ridge and star references retain their positions.
• The finish preserves the original landscape and main aurora color range.

6. Fix one failure

• If the effect resembles drifting clouds, reduce overall displacement and specify local changes within the bands.
• If the stars rotate, remove sky rotation and keep a few original star points as fixed references.

7. Ending and limits

The same aurora bands remain readable above the unchanged mountain ridge after a gentle local variation.

This original atmosphere design is not a travel recording, an aurora forecast or a measurement of natural motion.

If a save or download control is available, retain the complete clip alongside the first frame and the exact prompt.
