Runway, the cutting-edge AI-driven creative tool platform, is about to release its Gen3 version of the Motion Brush feature, which is a milestone update, especially notable for its built-in custom motion path feature. This feature empowers users with the ability to freely set unique motion directions in the motion brush editor, greatly enhancing the precision and flexibility of motion control in video projects.

Gen3 version of the Motion Brush editor has achieved a qualitative leap in both visual and functional aspects. The interface is more mature and intuitive, and it also incorporates powerful new features such as "Freeze" area and "Keyframe" editing. The "Freeze" option allows users to easily lock specific areas in the frame, while the "Keyframe" function provides a timeline of up to 10 seconds, enabling users to have unprecedented control over every subtle change in the video sequence.

In addition, the introduction of custom motion paths is a significant improvement of Gen3 compared to previous versions. It completely solves the regret of not being able to customize motion directions for selected areas in Gen2. This innovation not only demonstrates Runway's determination to move towards a more intuitive and user-friendly interface but also reaffirms its commitment to enabling creators of all skill levels to easily harness advanced AI technology.

Furthermore, Runway is also actively developing another groundbreaking feature called "Extended Video". This feature includes intelligent trimming options that allow users to accurately select key segments in the video and automatically generate extended content based on these segments, further expanding the boundaries of video creation.

The combination of Motion Brush and "Extended Video" features not only showcases Runway's comprehensive layout and profound strength in video editing and generation field but also makes it an invaluable assistant for professionals in various fields such as film production, marketing, education, and art creation. Through the introduction of these innovative tools, Runway is leading the creative industry into a new era driven by AI. It simplifies complex processes, strengthens creative control, establishes new industry standards for video generation and editing, and enables every creator to easily create professional-level animations and videos.
