用 AI 把图片变成视频
iiss 把静止的画面变成运动的镜头。放入一张产品图、人像或渲染场景，写下你希望发生什么，选择视频模型，即可得到一条带同步音频、可观看可下载可分享的电影感短片。
图生视频真实案例
以下每个案例都由 iiss 从一张参考图和一行运动提示词生成。
Slow cinematic push-in on the woman in the uploaded portrait photo. She turns her head gently toward the soft window light, hair moves slightly in a light breeze, shallow depth of field, quiet room ambience. Keep her face, dress, necklace, and the background exactly as in the reference image.
Animate the product in the uploaded image: a slow 15-degree orbit around the amber serum bottle, a warm highlight sweeping across the glass, fine dust motes drifting through the light beam, gentle bokeh shimmer in the dark background. Preserve the exact bottle, dropper, label, wooden surface, and colors from the reference.
Add gentle parallax and drifting clouds to the uploaded landscape. Grass sways in the breeze, light shifts across the hills, distant birds cross the sky, natural ambient sound. Keep the terrain, trees, and sky composition unchanged.
Slow reveal of the room in the uploaded interior photo: the camera glides gently forward through the space, sunlight through the arched window shifts softly across the wall, plant leaves sway lightly, calm room ambience. Keep the furniture, colors, artwork, and geometry exactly as in the reference.
让照片自然地动起来
描述运镜（缓推、环绕、横摇）、主体运动（风吹发丝、蒸汽上升、汽车驶离）和情绪。模型保留原图构图，添加可信的运动和声音。
把产品图变成短视频
把一张产品图变成 5-10 秒广告质感短片：产品旋转、薄雾流动、光束扫过。参考图让包装、配色和比例保持一致。
如何写好图生视频提示词
从上传的图片出发，只描述什么该动、怎么动。一个主体、一个运镜、一种情绪，效果最好。
Slow cinematic push-in on the subject in the uploaded image. Subtle facial movement, soft window light, shallow depth of field, quiet room ambience.
Animate the product from the uploaded image: a slow 15-degree orbit with a controlled highlight sweeping across the surface, gentle background mist, clean studio look, soft glass chime.
Add gentle parallax and drifting clouds to the uploaded landscape, grass swaying in the breeze, distant birds, natural ambient sound.
图生视频常见问题
什么是图生视频 AI？
图生视频 AI 把静态图片动画成短视频。你上传参考图并描述运动，模型在保留原图外观的同时生成 5-10 秒带音频的短片。
什么样的图片效果最好？
光线好、主体清晰的图片效果最好：产品图、人像、插画、渲染图和风景。因为视频从你的图片出发，构图由你掌控。
视频有多长？
5-10 秒，单镜头连续拍摄，带同步音频，可直接下载或分享。
能保持产品包装一致吗？
上传产品照片作为参考图，只描述运镜、灯光和氛围。检查结果并按需重新生成——好镜头通常需要几轮迭代。
