+
+X-CLIP extends the CLIP framework from images to videos by incorporating temporal modeling, enabling aligned video–text representations for efficient video understanding and recognition.
+
+Original paper: [Expanding Language-Image Pretrained Models for General Video Recognition (X-CLIP)](https://arxiv.org/abs/2208.02816)
+
+# XCLIP-B32F8
+
+This model uses the **X-CLIP Base-Patch32-8Frames** variant, which combines a ViT-Base backbone with 32×32 image patches and processes 8 video frames to capture both appearance and motion information. It is well suited for applications such as video classification, video retrieval, video-text matching, and zero-shot video understanding where efficient spatiotemporal reasoning is required.
