Sora is not the first text-to-video model. Earlier models include Emu by Meta, Gen-2 by Runway, Stable Video Diffusion by Stability AI, and recently Lumiere by Google. Lumiere, released just a few weeks ago, claimed to produce better video than its predecessors. But Sora appears to be more powerful than Lumiere in at least some respects. Sora can generate videos with a resolution of up to 1920 × 1080 pixels, and in a variety of aspect ratios, while Lumiere is limited to 512 × 512 pixels. Lumiere’s videos are around 5 seconds long, while Sora makes videos up to 60 seconds. Lumiere cannot make videos composed of multiple shots, while Sora can. Sora, like other models, is also reportedly capable of video-editing tasks such as creating videos from images or other videos, combining elements from different videos, and extending videos in time.
