Backprop, a GPU cloud provider for AI processes, recently showcased AI-generated video using an environment based on Open-Sora V1.2. The company showed four examples using different prompts, and the results were generally of average quality. But the hardware requirements for even these relatively tame samples are quite high.
According to the company blog post, “On a 3090, you can generate videos up to 240p and 4s. Higher values than that use more memory than the card has. Generation takes around 30s for a 2s video and around 60s for a 4s video.” That's a decent amount of computational power for only 424x240 output — a four-second video has just under ten million pixels in total.
