Open Sora can create AI-generated videos on an RTX 3090 GPU, but memory capacity limits it to 4-second 240p clips

Open Sora running on an RTX 3090 can only generate a four second 240p video before it hits it memory limits. It also takes a minute to create the video, with a 24fps frame rate. You'll need a lot more VRAM for longer, higher resolution videos.
