Officially, the introduction of the first and last frame feature makes the videoFiner control can be achieved in the opening and closing sections<\/strong>, thus improving the overall visual fluency. In addition, the model also demonstrates greater precision when dealing with complex scenes and semantics, and will be suitable for video creation that requires the expression of complex stories or concepts.<\/p>\n

At the same time, the new first and last frames feature further improves the consistency and stability of the video, which is especially suitable forProduct films, AI movies, AI skits<\/strong>and other specialized creative scenes.<\/p>\n

As previously reported by 1AI, the Kerin 2.1 series model was officially launched on May 29, generating 5s video in high-quality mode (1080p)Takes less than 1 minute<\/strong>..

The Keyline 2.1 model includes standard (720p) and high-quality (1080p) modes, focusing on cost-effective and efficient generation; the high-end Keyline 2.1 Master Edition offersSuperior motion performance and enhanced semantic response<\/strong>.<\/p>\n

In July of this year, the user data disclosed by Shutterstock showed that Keling AI has more than 45 million creators around the world, and the product has been iterated and upgraded more than 30 times since it was released, accumulatively generating more than 200 million videos and 400 million pictures.<\/p>","protected":false},"excerpt":{"rendered":"

August 15, 2011 - Keling 2.1 model under the banner of Racer has started the internal test of the new first and last frame function. According to the official introduction, this upgrade brings significant effect improvement: smoother \"movie-level\" camera control, silky and natural transitions, and accurate understanding of complex semantics. Officially, the introduction of the first and last frames function enables finer control of the beginning and end of the video, thus improving the overall visual fluency. In addition, the model demonstrates greater precision when dealing with complex scenes and semantics, and will be suitable for video creations that need to express complex stories or concepts. Users can customize the first and last frame images to generate coherent and high-quality video content, effectively overcoming pain points such as hard transitions and lack of text response in AI video generation.
