Inputs (10)
| Name | Type | Default | Description |
|---|---|---|---|
| vhs_filenames | * | Trigger input from VideoHelperSuite Combine Video so this node runs after preview videos are written. | |
| preview_folder | STRING | Folder containing the saved preview videos, or the VHS filename_prefix from the trainer node. If a filename_prefix is provided, this node automatically uses its parent output folder. | |
| output_name | STRING | LTXChunkRun | LoRA/output name used to filter matching preview videos and to name the final XYZ video. |
| completed_steps | INT | 00–1000000 | Current completed training step from the trainer node. |
| total_target_steps | INT | 30001–1000000 | Final training target step. The XYZ compare video is only created when completed_steps reaches this value. |
| cell_width | INT | 00–4096 | Width of each tile in the final comparison grid. Use 0 to auto-detect from the first preview video. Examples: 320 for many checkpoints, 512 for a balanced layout, 768 for larger tiles. |
| cell_height | INT | 00–4096 | Height of each tile in the final comparison grid. Use 0 to auto-detect from the first preview video. If labels are enabled, the label band is added automatically. |
| label_tiles | BOOLEAN | true | Adds a label band above each tile using the preview filename, which should include the LoRA name and step. |
| output_fps | INT | 241–120 | FPS for the final comparison video. Example: 24 for standard preview playback. |
| render_backend | COMBO | NVIDIA GPU (h264_nvenc) | Final XYZ export backend. CPU uses libx264. NVIDIA GPU uses NVENC for faster encoding when ffmpeg has NVENC support. Note: the grid compose filters still run in ffmpeg, so GPU mode mainly speeds up the encode stage. |
