Runway发布Gen-3 Alpha Extensions功能 视频可延长至40秒
Runway公司发布Gen-3Alpha Extensions功能，将AI视频生成时长扩展至40秒，并对所有用户开放，此举对数字内容创作产生革命性影响。用户仅需提供图片或文字输入，即可生成包含完整故事情节或广告内容的视频。该技术对广告制作、短视频创作等领域具有深远意义，大幅提升了创作效率。此外，Runway近期还推出了Gen-3Alpha Turbo版本，将视频生成速度提高7倍，并在8月初为图生视频功能添加了首尾帧控制，允许用户通过特定图像锚定AI生成的视频，确保生成内容的一致性和可预测性。这些技术突破和功能升级正在重塑AI辅助创作的可能性，为创作者提供了高效实现创意的工具。
