Symbols in this group are spelled `otio_transition_…`. An SDK drops that prefix.

## `enabled`

`otio_transition_enabled` · getter

Returns whether a transition is applied.

```c
OtioStatus otio_transition_enabled(
    const OtioDocument *source,
    OtioNode node_handle,

| Parameter | Type | Role |
| --- | --- | --- |
| `target` | `document` | document mut |
| `node_handle` | `node` | receiver |
| `enabled` | `bool` | input |

## `set_in_offset`

`otio_transition_set_in_offset` · setter

Sets how far a transition reaches into the item before it.

```c
OtioStatus otio_transition_set_in_offset(
    OtioDocument *target,
    OtioNode node_handle,
    OtioRationalTime offset,
    OtioBuffer *out_error);
```

| Parameter | Type | Role |
| --- | --- | --- |
| `target` | `document` | document mut |
| `node_handle` | `node` | receiver |
| `offset` | `OtioRationalTime` | input |

## `set_out_offset`

`otio_transition_set_out_offset` · setter

Sets how far a transition reaches into the item after it.

```c
OtioStatus otio_transition_set_out_offset(
    OtioDocument *target,
    OtioNode node_handle,
    OtioRationalTime offset,
    OtioBuffer *out_error);
```

| Parameter | Type | Role |
| --- | --- | --- |
| `target` | `document` | document mut |
| `node_handle` | `node` | receiver |
| `offset` | `OtioRationalTime` | input |
| `out_error` | `text` | error |

## `set_type`

`otio_transition_set_type` · setter

Sets the kind of transition.

```c
OtioStatus otio_transition_set_type(
    OtioDocument *target,
