Through the use of deep neural network technology, image-to-video AI can metamorphose still pictures into high-definition animated video from 24 to 60 frames per second. For example, Runway’s Gen-2 model is capable of producing a 5-second 1080p video within 30 seconds, and one rendering price may be as little as $0.12. The basic algorithm of such an AI video generator is the spatio-temporal attention mechanism. By the analysis of the image texture, the edge, and semantic detail (such as 99.3% face recognition rate), it predicted action sequences to execute indefinitely. Take Pika Labs for example. Its algorithm is trained against a dataset of one billion open source images with features such as the ability to generate 30 seconds’ worth of video clips at a time and a maximum 4K resolution and a 98% range of sRGB color gamut.
In practical applications, AI video-making technology has reduced the cost of content creation tremendously. In 2023, a platform for online shopping used Synthesia’s image to video AI software to produce product commercials. The price of one video was slashed from $5,000 for traditional production to $800, the length of the production was reduced from 7 days to 2 hours, and the return on investment (ROI) was increased by 320%. According to the Gartner report, 30% of enterprises’ marketing videos worldwide will rely on AI video Generators in 2025. The market size is forecasted to cross more than 12 billion US dollars with a compound annual growth rate of 47%. In efficiency optimization also, technological upgrades are observed. For example, the inference time of the Stable Video Diffusion model has been improved from 3.2 seconds per frame in the initial generation to 0.8 seconds per frame, power usage has decreased by 62%, and enables real-time rendering of dynamic light and shadow effects.
Industry cases have also validated its business value. Xinhua News Agency utilized the internally generated image to video ai system in 2024 to convert historical photos into commemorative videos. The monthly output exceeded 100,000 pieces, play times exceeded 500 million times, and the user interaction rate increased by 18%. Another typical scenario is the film and television industry. Hollywood studios also used Descript’s AI video tool to cut the cost of previewing the animation of storyboards from $12 per frame to $0.5 per frame. Meanwhile, it also accommodates 4K/120fps specifications with a 20:1 compression ratio. From the technical specifications perspective, the mainstream model’s motion prediction error rate has been below 0.15 pixels per frame, dynamic blur control accuracy is 95%, and it can simulate the effect of vegetation swing or water flow turbulence with a wind speed of 8m/s.
However, issues still persist data privacy and computing power demand. It would cost around 2.5PB labeled data to train a mid-sized ai video generator, the cost of the GPU cluster exceeds 3 million US dollars, and the video memory usage for a single inference reaches 48GB. For example, due to the limitation of the cloud computing power, the video extension function of MidJourney V6 can only be enjoyed by enterprise-level users, and the most basic monthly payment is $2,000. Despite this, technological innovation continues to drive popularity – TikTok’s AI template “Live Photo” released in 2023 has acquired more than 120 million users, and the average number of videos each individual creates per month has increased from 3.7 to 9.4, and the user stay time grew by 22%, demonstrating that the market demand for low-threshold AI animation products is growing exponentially.
