# LTXVSpatioTemporalGuidance - ComfyUI Built-in Node Documentation

> This node improves the spatial detail and motion coherence of LTXV video generation by running an extra pass at each sampling step.

This node improves the spatial detail and motion coherence of LTXV video generation by running an extra pass at each sampling step. During this pass, the self-attention of the selected transformer blocks is degraded to a value-passthrough, and the generation is guided away from the degraded result.

## Inputs

| Parameter       | Description                                                                                                                           | Data Type | Required | Range                    |
| --------------- | ------------------------------------------------------------------------------------------------------------------------------------- | --------- | -------- | ------------------------ |
| `model`         | The base model to apply spatio-temporal guidance to. The model is cloned and modified with a post-CFG guidance function.              | MODEL     | Yes      | —                        |
| `scale`         | The strength of the guidance applied to the denoised result. When set to 0, guidance has no effect. (default: 1.0)                    | FLOAT     | Yes      | 0.0 to 100.0 (step 0.01) |
| `blocks`        | Comma-separated transformer block indices to perturb. Only numeric values are used; any other characters are ignored. (default: "29") | STRING    | Yes      | —                        |
| `start_percent` | The fraction of the sampling process at which guidance begins. (default: 0.0)                                                         | FLOAT     | Yes      | 0.0 to 1.0 (step 0.001)  |
| `end_percent`   | The fraction of the sampling process at which guidance ends. (default: 1.0)                                                           | FLOAT     | Yes      | 0.0 to 1.0 (step 0.001)  |

Note: Guidance is only applied during the sampling interval between `start_percent` and `end_percent`. If `scale` is 0 or `blocks` contains no numeric values, the guided pass has no effect on the sampling process.

| ----------- | --------------------------------------------------------------------- | --------- |
| `MODEL`     | The cloned model with the spatio-temporal guidance function attached. | MODEL     |
