On August 15, Keling AI embarked on beta testing for the latest iteration of its 2.1 model, introducing groundbreaking first and last frame features. This enhancement heralds substantial advancements: it now boasts smoother "cinematic" camera motion control, seamless transitions, and unparalleled precision in complex semantic comprehension. Users can personalize the initial and final frame images to craft high-definition, coherent videos, thereby addressing challenges like jarring transitions and inadequate textual responses commonly encountered in AI-generated video content. Additionally, these new features elevate video consistency and stability, making them an ideal fit for professional applications such as product promotional videos, AI-crafted movies, AI short dramas, and beyond.
