# Timeline / Set Clip Timing
|
|
|
|
Adjust the timing of an existing clip identified by track + clip index. Any value left null is untouched, so this tool can tweak a single property or several at once.
|
|
|
|
## Inputs
|
|
|
|
- `assetPath` — required path to the `.playable` TimelineAsset.
|
|
- `trackName` / `trackIndex` — which track holds the clip (name wins; index default 0).
|
|
- `clipIndex` — required zero-based index of the clip on its track.
|
|
- `start` — optional new start time (seconds).
|
|
- `duration` — optional new duration (seconds).
|
|
- `clipIn` — optional clip-in / trim offset into the source asset (seconds).
|
|
- `blendInDuration` / `blendOutDuration` — optional crossfade blend durations (seconds).
|
|
- `easeInDuration` / `easeOutDuration` — optional ease (fade) durations (seconds).
|
|
- `timeScale` — optional playback time scale of the clip.
|
|
|
|
## Behavior
|
|
|
|
Resolves the clip, applies each supplied value, saves the asset, and returns the resulting timing. Runs on the Unity main thread.
|
|
|
|
## How to Call
|
|
|
|
```bash
|
|
unity-mcp-cli run-tool timeline-clip-set-timing --input '{
|
|
"assetPath": "string_value",
|
|
"clipIndex": 0,
|
|
"trackName": "string_value",
|
|
"trackIndex": 0,
|
|
"start": 0,
|
|
"duration": 0,
|
|
"clipIn": 0,
|
|
"blendInDuration": 0,
|
|
"blendOutDuration": 0,
|
|
"easeInDuration": 0,
|
|
"easeOutDuration": 0,
|
|
"timeScale": 0
|
|
}'
|
|
```
|
|
|
|
> For complex input (multi-line strings, code), save the JSON to a file and use:
|
|
> ```bash
|
|
> unity-mcp-cli run-tool timeline-clip-set-timing --input-file args.json
|
|
> ```
|
|
>
|
|
> Or pipe via stdin (recommended):
|
|
> ```bash
|
|
> unity-mcp-cli run-tool timeline-clip-set-timing --input-file - <<'EOF'
|
|
> {"param": "value"}
|
|
> EOF
|
|
> ```
|
|
|
|
|
|
### Troubleshooting
|
|
|
|
If `unity-mcp-cli` is not found, either install it globally (`npm install -g unity-mcp-cli`) or use `npx unity-mcp-cli` instead.
|
|
Read the /unity-initial-setup skill for detailed installation instructions.

|
|
| `clipIn` | `number` | No | Optional clip-in (trim offset into the source asset) in seconds. |
|
|
| `blendInDuration` | `number` | No | Optional blend-in (crossfade) duration in seconds. |
|
|
| `blendOutDuration` | `number` | No | Optional blend-out (crossfade) duration in seconds. |
