Generative video models seem to be debuting daily. Pyramid Flow, among the latest, aims for realism, producing dynamic video sequences that have temporal consistency and rich detail while being open source and free. The model can create clips of up to 10 seconds using both text and image prompts. It offers a cinematic look, supporting 1280×768 pixel resolution clips at 24 fps. Developed by a consortium of researchers from Peking University, Beijing University and Kuaishou Technology, Pyramid Flow harnesses a new technique that starts with low-resolution video, outputting at full-res only at the end of the process.

Researchers at China’s University of Shanghai for Science and Technology have invented an ultrahigh density optical disc format they claim can store up to 1.6 petabits — more than 1,500 terabytes, or 125,000 gigabytes — of data. While the new discs are said to look like typical Blu-rays, the data is written to one hundred layers in a 3D stacking architecture by a 54-nanometer laser that is about one-tenth the size of visible light waves. The same laser is used to read the data back. The tech is said to present “a promising solution for cost effective, long-term archival data storage.” Continue reading New Chinese Optical Disc Promises Petabyte-Plus of Storage
