Video Enhance - Prepare Video and Anchors
Creates an independent full-frame Video Enhance job, temporary LTX video, and regularly spaced Z-Image anchors while preserving the exact source frames and metadata for final restoration.

Inputs (11)
| Name | Type | Default | Description |
|---|---|---|---|
| video_frames | IMAGE | Connect the full IMAGE batch from VHS Load Video. These original frames remain unchanged in the context and are used to enforce the exact final resolution and frame count. | |
| anchor_interval | COMBO | 16 frames (recommended) | Spacing between full-frame Z-Image guide anchors. The first and final frames are always included. Smaller spacing gives LTX more enhanced references but requires more Z-Image runs. |
| anchor_width | INT | 768128–4096 | Requested width used only for Z-Image anchor enhancement. It does not change the source or final video resolution. |
| anchor_height | INT | 432128–4096 | Requested height used only for Z-Image anchor enhancement. Choose dimensions matching the source aspect ratio unless using Fit with letterbox. |
| ltx_width | INT | 960128–4096 | Temporary LTX working width. Higher values can improve spatial detail but substantially increase VRAM use and runtime. Final output is restored to the source width. |
| ltx_height | INT | 544128–4096 | Temporary LTX working height. Higher values can improve spatial detail but substantially increase VRAM use and runtime. Final output is restored to the source height. |
| dimension_multiple | COMBO | 32 (recommended) | Rounds requested anchor and LTX dimensions to a model-friendly multiple. The resolved dimensions are exposed as outputs so downstream loaders can match them exactly. |
| fit_mode | COMBO | Fit with letterbox (preserve all) | Fit preserves the entire frame and adds black bars if aspect ratios differ. Crop fills the dimensions while trimming edges. Stretch changes aspect ratio and is usually not recommended. |
| resize_method | COMBO | Bicubic (recommended) | Interpolation used for temporary anchor and LTX resizing. Bicubic is a strong general default. Area can be useful for large downscales. |
| fallback_fps | FLOAT | 24.0001–240 | Used only when video_info is not connected or lacks FPS metadata. Connect video_info to preserve exact source timing. |
| video_infoopt | VHS_VIDEOINFO | Connect VHS Load Video video_info so the temporary LTX video uses the exact source FPS. |
