Viva is a free AI generation tool and community offering Text-to-Image, Image-to-Image, Text-to-Video, and Image-to-Video capabilities, along with powerful AI editing tools. Users can upscale images, redraw any content, making images and videos higher quality and 4K resolution. Viva makes AI creation easier and more efficient. The overseas product Viva has released its first open-source Sora architecture video generation model, which is currently free to use. Text-to-video can generate a 5-second video per instance, while image-to-video generates a 4-second video. This is currently the video generation model with the largest motion range, and its image resolution is also the largest among currently available video generation products. The effect of text-to-video is better than that of image-to-video. If used, it is recommended to adjust the motion amplitude to around 20 for optimal results. Viva's strength lies in generating good vertical videos. Many video model demos are horizontal videos, and the vertical performance is not good. However, short videos are the majority of video content, so the quality of vertical video generation is a crucial indicator. However, consistency has not been well maintained in some tests. It does not exhibit the powerful physical property simulation and 3D consistency of Sora.
