用文字提示词生成视频
写下你想看到的画面——主体、动作、运镜、光线——iiss 生成一条带声音的电影感短片。多个模型让你在速度和细节之间按需取舍。
文生视频真实案例
以下每个案例都由 iiss 从一段文字提示词生成。
Create an 8-second vertical 9:16 luxury perfume commercial in one continuous cinematic shot. A sculptural transparent perfume bottle filled with warm amber liquid stands on a polished black obsidian pedestal in a dark studio. A narrow golden beam slowly sweeps across the bottle, revealing precise glass reflections and the liquid inside. Fine atmospheric mist drifts gently behind it as the camera makes a slow, controlled push-in. Add a delicate glass chime, no voiceover, no music. No readable label, no logos, no scene cuts.
Create an 8-second vertical 9:16 cinematic ASMR video in one continuous macro shot. A translucent ruby-red glass strawberry rests on a matte black cutting board under soft studio lighting. A polished kitchen knife slowly makes one clean slice through the strawberry, revealing tiny jewel-like glass seeds and refracting red crystal layers. Include crisp, delicate slicing sounds and a subtle crystalline crackle synchronized with the cut. No flying shards, no speech, no music, no text, no scene cuts.
Create an 8-second vertical 9:16 cinematic horror video in one continuous shot. The camera slowly moves forward down an abandoned hospital corridor at night. Old fluorescent lights flicker overhead, peeling paint and dusty doors line the hallway, and a thin layer of mist hangs near the floor. Behind a frosted glass door at the far end, a tall human-like silhouette briefly crosses from left to right, then disappears. Add a faint electrical hum, slow footsteps, and one distant metallic door click. No gore, no jump cuts.
Cinematic aerial shot flying slowly over a foggy city skyline at dawn, the camera gliding forward between glass towers as the first sunlight breaks through the haze, distant traffic hum and soft wind, one continuous shot, no text, no logos.

如何写好视频提示词
写明主体和动作，加一个运镜、一种光线情绪和你期待的声音。一条提示词一个镜头，效果最好。
An 8-second vertical luxury perfume commercial: a transparent bottle on black obsidian, a golden beam sweeps across as mist drifts, slow push-in, delicate glass chime. No text, no logos.
8-second macro ASMR: a translucent ruby-glass strawberry sliced cleanly on a black board, jeweled seeds revealed, crisp slicing sound and crystalline crackle. One continuous shot.
Slow dolly down an abandoned hospital corridor at night, flickering fluorescents, thin mist, a silhouette crossing behind frosted glass, electrical hum and a distant door click.
文生视频常见问题
什么是文生视频 AI？
文生视频 AI 根据文字描述生成短视频。你描述主体、动作、运镜和氛围，模型渲染出 5-10 秒带同步音频的短片。
视频有声音吗？
有。iiss 生成的短片自带同步音频——环境声、音效和质感与画面动作匹配。
视频有多长？
5-10 秒，单镜头。足够用于社交短片、广告和 B-roll，也足够短以便快速迭代。
可以从照片开始吗？
可以——在生成器里上传参考图即可保持特定外观。图生视频页面有该工作流的详细说明。
