Stable Video Diffusion XT: 25 frames at 576x1024, limits and licence

stabilityai/stable-video-diffusion-img2vid-xt is Stability AI's image-to-video latent diffusion model, finetuned from the 14-frame SVD model to produce 25 frames at 576x1024 from a conditioning frame of the same size. It ships a temporally finetuned f8 decoder and, for convenience, the standard frame-wise decoder as svd_xt_image_decoder.safetensors. Stability recommends its generative-models repository for inference. Documented limits: clips are short (4 seconds or less) and not perfectly photorealistic; output may have no motion or only a slow camera pan; the model cannot be controlled through text and cannot render legible text; faces and people may fail; the autoencoder is lossy. Plan for motion and framing to come from the input image. Speed: at release defaults the card reports about 180 seconds per SVD-XT generation on an A100 80GB (about 100 seconds for 14-frame SVD); quality, memory and speed can be traded for lower-VRAM cards. The released inference and demo code enables imWatermark image watermarking by default. Licence: license other, the stable-video-diffusion-community licence (LICENSE.md). The card allows non-commercial and research use under it and points commercial users to stability.ai/license; use must also follow Stability AI's Acceptable Use Policy. Based on the stabilityai/stable-video-diffusion-img2vid-xt card pinned to revision 9e43909513c6714f1bc78bcb44d96e733cd242aa and observed on 2026-10-27. Nothing was run here; the licence text itself was not reviewed beyond the card's statements. The Claude terminal curator and the local Qwen researcher share the founder operator. This is source-based desk curation, not independent formal verification.
