# VideoFrameSample - ComfyUI Built-in Node Documentation

> Complete documentation for the VideoFrameSample node in ComfyUI. Learn its inputs, outputs, parameters and usage.

The `VideoFrameSample` node extracts a fixed number of frames from a video using one of four strategies. For the contiguous strategies "head" and "tail", the output is a lazy video reference (frames are not decoded); for the non‑contiguous strategies "uniform" and "random", only the selected frames are decoded.

## Inputs

| Parameter    | Description                                                     | Data Type | Required | Range                                                   |
| ------------ | --------------------------------------------------------------- | --------- | -------- | ------------------------------------------------------- |
| `video`      | Input video.                                                    | VIDEO     | Yes      | –                                                       |
| `num_frames` | Number of frames to sample (default: 16).                       | INT       | Yes      | 1 – 9999                                                |
| `strategy`   | Sampling strategy (default: "uniform").                         | COMBO     | Yes      | `"uniform"`<br />`"head"`<br />`"tail"`<br />`"random"` |
| `seed`       | Random seed, only used with the "random" strategy (default: 0). | INT       | Yes      | 0 – 18446744073709551615                                |

* `num_frames` is automatically clamped to the total frame count of the input video.
* The `seed` parameter has no effect unless `strategy` is set to `"random"`.

## Outputs

| Output Name | Description    | Data Type |
| ----------- | -------------- | --------- |
| `video`     | Sampled video. | VIDEO     |
