# LTXVSpatioTemporalGuidance - ComfyUI Built-in Node Documentation

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

This node improves the spatial detail and motion coherence of LTXV video generation by running one 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 that degraded result.

## Inputs

| Parameter       | Description                                                                                                                           | Data Type | Required | Range                    |
| --------------- | ------------------------------------------------------------------------------------------------------------------------------------- | --------- | -------- | ------------------------ |
| `model`         | The base model to apply spatio-temporal guidance to. The model is cloned and a post-CFG guidance function is attached to the clone.   | MODEL     | Yes      | —                        |
| `scale`         | The strength of the guidance applied to the denoised result. When set to 0, the 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. This is an advanced parameter. (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. This is an advanced parameter. (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`. Outside that interval, the original denoised result is returned unchanged. If `scale` is 0 or `blocks` contains no numeric values, the guided pass has no effect on the sampling process.

## Outputs

| Output Name | Description                                                           | Data Type |
| ----------- | --------------------------------------------------------------------- | --------- |
| `MODEL`     | The cloned model with the spatio-temporal guidance function attached. | MODEL     |
