# GES action types
## edit-container
``` validate-scenario
edit-container,
[playback-time=(double,string)],
container-name=(string),
position=(double or string),
[edit-mode=(string)],
[edge=(string)],
[new-layer-priority=(int)];
```
Allows to edit a container (like a GESClip), for more details, have a look at:
ges_container_edit documentation, Note that the timeline will
be commited, and flushed so that the edition is taken into account
* Implementer namespace: ges
### Parameters
Parameters:
* `playback-time`:(optional): The playback time at which the action will be executed
Possible variables:
* `position`: The current position in the stream
* `duration`: The duration of the stream
Possible types: `double,string`
Default: 0.0
* `on-message`:(optional): Specify on what message type the action will be executed.
If both 'playback-time' and 'on-message' is specified, the action will be executed
on whatever happens first.
Possible types: `string`
Default: (null)
