RIFE Frame Interpolation (fabric)

An Apple Core AI conversion of TensorForger/RIFE-safetensors — a frame interpolation network that takes two stacked RGB frames and synthesizes the intermediate frame between them. Produced by coreai-fabric and indexed by coreai-catalog.

Frame interpolation, not a generator. This is a single-forward interpolator — two frames in, one synthesized frame at t=0.5 out. No temporal model, no audio. The host owns frame decode/encode and resizing each frame to a multiple of 32 before feeding the graph.

Use it — this needs host code you supply

The bundle is a single static-size graph: frames (1×6×256×256, img0 and img1 concatenated on the channel axis, RGB in [0,1]) in → the interpolated frame (1×3×256×256) out. You supply the video demux/mux, frame resizing, and any multi-t or recursive-interpolation loop in your host code (Swift or Python).

pip install coreai-catalog && coreai-catalog install rife-4-interp

Requirements

• Deployment: macOS 27.0+ / iOS 27.0+, Xcode 27+. The asset serializes with minimum_os v27, so the on-device Swift runtime requires macOS/iOS 27+. A Mac on macOS 26 can convert and inspect it but not run it on-device.
• Apple Silicon.

Verification (output parity)

• Gate A (structure): passed — the bundle's layout + metadata were validated; the graph loads.
• Gate B — graph_output_cosine: 1.000000 min output cosine (median 1.000000) vs the fp32 torch reference network over 8 seeded frame pairs, measured on apple_silicon. Certifies the export computes the SAME output as the source — a conversion-fidelity metric, not task accuracy.
• This certifies the export is numerically faithful to the source network — it does NOT certify perceptual interpolation quality on your footage. Reproduce with coreai-fabric verify.
