Image-to-Video
Animate your image into 25 frames of 1024x576 pixels freely, without account, without watermark and download the video
This demo is based on Stable Video Diffusion artificial intelligence.
No prompt or camera control is handled here.
To control motions, rather use MotionCtrl SVD.
If you need 128 frames, rather use ExVideo.
