Recently, AI-driven animation generation technology (such as AI Kiss) has significantly enhanced the realism of character movements and expressions using deep learning models and neural network algorithms. For instance, the MetaHuman Creator unveiled by Unreal Engine 5 in 2023, along with the AI Kiss technology, can generate facial animations that are highly realistic within 30 seconds. The amount of data is reduced by 70% compared to regular manual production and the error rate in facial muscle movement is less than 0.3 millimeters, which achieves film quality accuracy. According to statistics reported by Epic Games, animation production time through this technology has been cut from 6 weeks to 3 days, cost has been reduced by 58%, and single-frame rendering costs have dropped from $5 to $0.8.
Within the entertainment industry, in Disney’s 2022 animated film “Filling House”, ai kiss technology was used to render 78% of the minor character expression animation in order to let the team complete the work initially taking two years within nine months and save labor costs of 12 million US dollars. In addition, NVIDIA’s GAN (Generative Adversarial Network) architecture reduced the rate of gait error of virtual actors from 15% to 2% and improved the smoothness of joint motion by 90% by learning from over 5 million hours of human motion. A blind test was conducted among audience samples in 2023 which showed that 61% of the test samples were unable to identify differences in AI-rendered characters and human actors in expressions with a 89% emotional delivery level.
From the business perspective, deployment of AI Kiss technology in gaming has been beneficial. Following the use of AI-generated facial animation technology in the international edition of Tencent’s “Honor of Kings”, character design effectiveness was doubled. Production cost of a single character was reduced from 120,000 yuan to 30,000 yuan and user retention was increased by 17% due to “expression authenticity” improvement. As IDC predicted, by 2025 the penetration ratio of AI technology in the world animation production market will be 45%, and the compound annual growth rate will be 31%. Among them, the size of the expression and motion generation sub-market will be expected to exceed 7.2 billion US dollars.
Technical bottlenecks still exist. For example, if in a high-complexity lighting and shading scene facial reflection accuracy by AI Kiss is only 82% and must resort to manual post-correction in the next phase, then extra working hours increase by around 15%. And the animation failure rate of excess expressions (fear or ecstasy) is 12%, several times that of human animators’ 3%. Despite this, Stanford University’s 2023 report says that by employing reinforcement learning and multimodal data fusion, AI animation can be enhanced to a peak signal-to-noise ratio (PSNR) of 48 dB, which approaches the 50 dB of the human eye. Five years down the line, it is hoped that full-process automated production can be achieved.
Now, AI Kiss technology has become step by step the “efficiency lever” of the animation industry. From Hollywood to independent studios, its precision-high and cost-saving features are reshaping industry standards, and the corresponding level of the pace of technological iteration versus market needs will determine if it can actually break through the “Valley of terror” pitfall and reach a fully realistic new paradigm.
