| # RIFE v4.9 (ONNX) |
|
|
| `rife49.onnx` — an ONNX export of **RIFE v4.9** for video frame interpolation |
| (synthesising the in-between frames when raising a video's frame rate). Runs |
| client-side with onnxruntime-web on the WASM or WebGPU execution providers. |
|
|
| ## Inputs / outputs |
|
|
| - **Inputs:** `img0` float32 `[1, 3, H, W]`, `img1` float32 `[1, 3, H, W]`, |
| `timestep` float32 `[1]` |
| - **Output:** `output` float32 `[1, 3, H, W]` — the interpolated frame at |
| `timestep` (0..1) between `img0` and `img1` |
| - Planar RGB (CHW), values in 0..1. `H` and `W` are padded to a multiple of 32 |
| for reference quality. |
