+# VideoMAE (huge-sized model, fine-tuned on Kinetics-400) 
+
+VideoMAE model pre-trained for 1600 epochs in a self-supervised way and fine-tuned in a supervised way on Kinetics-400. It was introduced in the paper [VideoMAE: Masked Autoencoders are Data-Efficient Learners for Self-Supervised Video Pre-Training](https://arxiv.org/abs/2203.12602) by Tong et al. and first released in [this repository](https://github.com/MCG-NJU/VideoMAE). 
+
+Disclaimer: The team releasing VideoMAE did not write a model card for this model so this model card has been written by the Hugging Face team.
+
+## Model description
+
+VideoMAE is an extension of [Masked Autoencoders (MAE)](https://arxiv.org/abs/2111.06377) to video. The architecture of the model is very similar to that of a standard Vision Transformer (ViT), with a decoder on top for predicting pixel values for masked patches.
+
+Videos are presented to the model as a sequence of fixed-size patches (resolution 16x16), which are linearly embedded. One also adds a [CLS] token to the beginning of a sequence to use it for classification tasks. One also adds fixed sinus/cosinus position embeddings before feeding the sequence to the layers of the Transformer encoder.
+
+By pre-training the model, it learns an inner representation of videos that can then be used to extract features useful for downstream tasks: if you have a dataset of labeled videos for instance, you can train a standard classifier by placing a linear layer on top of the pre-trained encoder. One typically places a linear layer on top of the [CLS] token, as the last hidden state of this token can be seen as a representation of an entire video.
+
+## Intended uses & limitations
+
+You can use the raw model for video classification into one of the 400 possible Kinetics-400 labels.
+
+### How to use
+
+Here is how to use this model to classify a video:
+
+```python
+from transformers import VideoMAEFeatureExtractor, VideoMAEForVideoClassification
+import numpy as np
+import torch
+
+video = list(np.random.randn(16, 3, 224, 224))
+
+feature_extractor = VideoMAEFeatureExtractor.from_pretrained("sandstorm12/videomae-huge-finetuned-kinetics")
+model = VideoMAEForVideoClassification.from_pretrained("sandstorm12/videomae-huge-finetuned-kinetics")
+
+inputs = feature_extractor(video, return_tensors="pt")
+
+with torch.no_grad():
+  outputs = model(**inputs)
+  logits = outputs.logits
+
+predicted_class_idx = logits.argmax(-1).item()
+print("Predicted class:", model.config.id2label[predicted_class_idx])
+```
