A new technique called TurboDiffusion claims to be able to speed up artificial intelligence video generation speeds up to 200 times at large scale, without compromising overall image quality, according to a recently published paper.
The technique reduced the time needed to generate a five-second standard-definition video clip from more than three minutes to just 1.9 seconds – a speedup of almost 100 times – when tested on a consumer system with NvidiaBeijing’s RTX 5090 graphics processing unit, according to Beijing researchers Qinghua UniversityAI model developer Shengshu Technology and University of California, Berkeleyin an article published late last week.
The time needed to generate a five-second high-definition video on the same machine was reduced from nearly 80 minutes to 24 seconds, about 200 times faster, according to an experiment cited in the article.
Currently, it takes a user between three and five minutes to generate a standard five-second video on Shengshu’s Vidu platform. OpenAI had also stated that its text-to-video model, Sora, took several minutes to render a short clip.
TurboDiffusion highlights the rapid progress made by Chinese researchers in advancing AI video generation technology since OpenAI introduced Sora in February 2024.
Accelerated video creation represents a significant change, as the use of video generation templates would no longer be a bottleneck in the production process, according to industry analyst Kyon Xu.
