Inputs (14)
| Name | Type | Default | Description |
|---|---|---|---|
| images | IMAGE | Input image batch. Output frame count: 2x=(2N-1), 4x=(4N-3), 8x=(8N-7). | |
| model | SPEED_VFI_MODEL | SPEED model from the Load SPEED Model node. | |
| multiplier | COMBO | 2 | SPEED is midpoint-only: 4x and 8x use recursive midpoint passes. |
| clear_cache_after_n_frames | INT | 101–100 | Clear CUDA cache every N frame pairs to prevent VRAM buildup. Lower = less VRAM but slower. |
| keep_device | BOOLEAN | true | Keep the ~235M-parameter model on GPU between batches. Faster, but uses substantial VRAM. |
| all_on_gpu | BOOLEAN | false | Store all intermediate frames on GPU instead of CPU. Much faster (no transfers) but requires enough VRAM for all frames. Recommended for 48GB+ cards. |
| batch_size | INT | 11–64 | Number of frame pairs to process simultaneously. Higher = faster but uses more VRAM. Start with 1, increase until VRAM is full. Recommended: 1 for 8GB, 2-4 for 24GB, 4-16 for 48GB+. SPEED is stochastic, so changing batch size can change how seeded noise is assigned to pairs. |
| chunk_size | INT | 00–10000 | Process the source in overlapping chunks to bound VRAM. SPEED remains repeatable for the same seed and settings, but changing chunk or batch boundaries can change its stochastic result. |
| source_fps | FLOAT | 0.000–1000 | Input frame rate. Required when target_fps > 0. |
| target_fps | FLOAT | 0.000–1000 | Target output FPS. When > 0, overrides multiplier and auto-computes a power-of-2 oversample up to 8x, then selects frames. 0 = use multiplier. |
| seed | INT | 00–2147483647 | SPEED starts from random pixel noise. The seed makes the same execution settings repeatable without reloading the model. |
| segment_index | INT | 00–10000 | Zero-based segment to process. Adjacent segments overlap by one source frame. |
| segment_size | INT | 5002–10000 | Input frames per segment. Save each segment before processing the next to bound RAM. |
| settingsopt | VFI_SETTINGS | Auto-tuned settings from VFI Optimizer. Overrides batch_size, chunk_size, keep_device, all_on_gpu, clear_cache_after_n_frames. |
