enhancement: Repeat action when create long video #405
Description
当前现状
When generating long videos (over 10 seconds or involving multiple rounds), the system tends to repeat the same actions from the previous round instead of continuing the motion naturally.
This creates noticeable duplication in movement, making the video feel artificial and loop-like rather than fluid.
期望改进
The system should support smooth continuation of actions across multiple rounds instead of repeating them.
价值与场景
This enhancement improves realism and usability in long-form video creation, especially for content that requires continuous motion.
