fal 推出 H3 Max Relight 视频重打光功能
fal 推出 H3 Max Relight，可对任意视频重新打光：上传视频后在内置 Lighting studio 中选颜色、让每盏灯绕主体环绕并调节强度与柔和度，它会逐帧重打光以匹配设置，同时保留原主体、运动、镜头运动和音频，可从平淡日光改为黄金时刻、霓虹或品牌配色而无需补拍。该功能由 H3 Max 提供支持，fal 称其在整体质量、提示词理解和美学上对领先视频模型排名第一。
Introducing H3 Max Relight, an easy way to change the lighting of any video.
Upload an existing video, then design your light in the built-in Lighting studio: pick colors, orbit each light around the subject, and dial in intensity and softness. H3 Max Relight relights every frame to match while preserving the original subjects, motion, camera movement, and audio. Go from flat daylight to golden hour, neon, or your brand palette, all without another shoot.
Powered by H3 Max, the #1 model for overall quality, prompt understanding, and aesthetics against leading video models.
