CinemaCLIP

CinemaCLIP-1.0.0

CinemaCLIP is a ViT-B-32-256 fine-tune specialized for understanding the visual language of cinema at a frame level. It is a hybrid CLIP model with 23 classifier heads that represent a comprehensive taxonomy built with domain experts. For more info, see our launch blog post.

This repository ships three serialized forms of the same model:

• Torch (model.safetensors) — load via the cinemaclip Python package.
• CoreML (ImageEncoder.mlmodel, ImageEncoder.mlpackage and TextEncoder.mlpackage) — for on-device Apple Neural Engine inference.
• ONNX (ImageEncoder.onnx, TextEncoder.onnx, plus _fp16 variants) — for cross-platform inference.

Install

pip install cinemaclip            # core
pip install "cinemaclip[coreml]"  # CoreML export/inference
pip install "cinemaclip[onnx]"    # ONNX export/inference

Usage (PyTorch)

from PIL import Image
from cinemaclip import CinemaCLIP

model = CinemaCLIP.from_pretrained("OZU-Technology/CinemaCLIP").eval()

# End-to-end classification on a PIL image
image = Image.open("still.jpg").convert("RGB")
predictions = model.predict_image(image)
predictions["classifier_preds"]  # Classifier predictions
predictions["clip_image_embedding"]

# Just the image embedding
x = model.preprocess(image).unsqueeze(0)
image_embedding = model.encode_image(x, normalize=True)   # [1, 512]

# Just the text embedding
tokens = model.tokenizer(["a medium closeup of "])
text_embedding = model.encode_text(tokens, normalize=True)  # [1, 512]

The CinemaCLIP.predict_image method is demonstrative for how to get post-processed classifier outputs from the model. It is not super efficient or production ready, and must be treated as a reference above all else.

Usage (CoreML)

import coremltools as ct
from PIL import Image

img_encoder = ct.models.MLModel("ImageEncoder.mlpackage")
# Input must be 256x256 RGB, resized with BICUBIC for parity with the released torch outputs.
img = Image.open("still.jpg").convert("RGB").resize((256, 256), Image.Resampling.BICUBIC)
out = img_encoder.predict({"Image": img})
embedding = out["clip_image_embedding"]    # [512]
probabilities = out["probabilities"]       # [101] — concat of 23 per-category outputs

# TODO
text_encoder = ct.models.MLModel("TextEncoder.mlpackage")

Usage (ONNX)

from PIL import Image
from onnxruntime import InferenceSession
from torchvision import transforms as T

img = Image.open("still.jpg").convert("RGB")
preprocess = T.Compose([
    T.Resize((256, 256), interpolation=T.InterpolationMode.BICUBIC),
    T.ToTensor(),   # yields float tensor in [0, 1] — no mean/std normalization
])
x = preprocess(img).unsqueeze(0).numpy()

session = InferenceSession("ImageEncoder.onnx", providers=["CPUExecutionProvider"])
emb, probs = session.run(None, {"Image": x})

Output structure

probabilities is a flat [101] vector — the concatenation of all 23 classifier heads' post-activation outputs. Label names and positions are in the shipped CinemaNetSchema.json:

import json
schema = json.load(open("CinemaNetSchema.json"))
label_names = schema["probabilities_labels"]  # len == 101

The classifier heads are a mix of 3 types of classifiers:

• Single label (softmax activation)
• Multi label (sigmoid activation)
• Binary (sigmoid activation)

Evaluation

CinemaCLIP outperforms not only the largest existing CLIP models (up to 28x larger), but also leading VLMs in cinematic understanding tasks (we benchmarked against the leading 4B VLMs).

Two inference modes are reported for CinemaCLIP:

• Classifier — the shipped supervised heads on the CinemaCLIP image embedding.
• 0-shot — zero-shot text/image similarity using CinemaCLIP's own text encoder.

The shot.lighting.direction head ships in the classifier heads but has been excluded from the table above being a multi-label classifier.
