# Trim

> Clip a video segment by start and end offset, or by start and duration.

Trim a video to a shorter clip by setting the start offset (`so_`) and either an end offset (`eo_`) or a duration (`d_`). Offsets are accurate to the second.

<Info>
  Trimming runs first in the pipeline, so any later transform processes only the trimmed segment.

## How to trim a clip?

Set the start offset to **5 s** (`so_5`), then define the end with either `eo_` (an absolute point on the timeline) or `d_` (a length from the start).

| Token | Name         | Example | What it does                             |
| ----- | ------------ | ------- | ---------------------------------------- |
| `so_` | Start offset | `so_5`  | Start the clip at **5 s**                |
| `eo_` | End offset   | `eo_15` | End the clip at **15 s** on the timeline |
| `d_`  | Duration     | `d_10`  | Keep **10 s** from the start offset      |

`eo_` and `d_` are two ways to define the same clip end: `so_5,eo_15` and `so_5,d_10` both produce the segment from **5 s** to **15 s**.

We recommend trimming before converting to GIF (e.g. `so_5,d_10,f_gif`) because a shorter segment keeps the GIF file size down. See [Convert to GIF](/docs/video/gif).
