# VideoFrameSample - ComfyUI Built-in Node Documentation
> The VideoFrameSample node extracts a fixed number of frames from a video using one of four strategies.
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` | uniform: evenly spaced, head: first N, tail: last N, random: random sorted (default: "uniform"). | COMBO | Yes | "uniform"
"head"
"tail"
"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"`.
* When `strategy` is `"uniform"` and `num_frames` is 1, the middle frame of the video is selected.
* An unrecognized `strategy` value raises an error.
## Outputs
| Output Name | Description | Data Type |
| - | - | - |
| `video` | Sampled video. | VIDEO |
