videoprism-large-f8r288-pt

PyTorch port of google/videoprism-large-f8r288 (Google DeepMind's VideoPrism). The original release ships JAX/Flax weights only; this repo hosts a self-contained PyTorch implementation that produces numerically-equivalent outputs (cosine sim 1.000000 vs the JAX reference). Source: <https://github.com/Skovorp/torch_videoprism>.

Usage

python

from transformers import AutoModel, AutoProcessor

model = AutoModel.from_pretrained("sposiboh/videoprism-large-f8r288-pt", trust_remote_code=True)
processor = AutoProcessor.from_pretrained("sposiboh/videoprism-large-f8r288-pt", trust_remote_code=True)

# Process a video file (or a list of frames / numpy / torch tensor):
inputs = processor(videos="path/to/video.mp4", return_tensors="pt")
outputs = model(**inputs)
embedding = outputs.last_hidden_state    # shape: (B, T*N, model_dim) — token sequence

Frames are sampled uniformly to the model's native frame count and resized bilinearly to image_size × image_size. Pixels are scaled to [0, 1].
