# class pixeltable.iterators.VideoSplitter
Iterator over segments of a video file, which is split into fixed-size segments of length `segment_duration`
seconds.
Args:
duration: Video segment duration in seconds
overlap: Overlap between consecutive segments in seconds. Only available for `mode='fast'`.
min\_segment\_duration: Drop the last segment if it is smaller than min\_segment\_duration.
mode: Segmentation mode:
* `'fast'`: Quick segmentation using stream copy (splits only at keyframes, approximate durations)
* `'accurate'`: Precise segmentation with re-encoding (exact durations, slower)
video\_encoder: Video encoder to use. If not specified, uses the default encoder for the current platform.
Only available for `mode='accurate'`.
video\_encoder\_args: Additional arguments to pass to the video encoder. Only available for `mode='accurate'`.
## method accurate\_iter()
```python theme={"theme":{"light":"light-plus","dark":"dark-plus"}}
accurate_iter() -> Iterator[dict[str, Any]]
```
## method close()
```python theme={"theme":{"light":"light-plus","dark":"dark-plus"}}
close() -> None
```
Close the iterator and release all resources
## method create()
```python theme={"theme":{"light":"light-plus","dark":"dark-plus"}}
create(**kwargs: Any) -> tuple[type[ComponentIterator], dict[str, Any]]
```
## method fast\_iter()
```python theme={"theme":{"light":"light-plus","dark":"dark-plus"}}
fast_iter() -> Iterator[dict[str, Any]]
```
## method input\_schema()
```python theme={"theme":{"light":"light-plus","dark":"dark-plus"}}
input_schema() -> dict[str, pixeltable.type_system.ColumnType]
```
Provide the Pixeltable types of the init() parameters
The keys need to match the names of the init() parameters. This is equivalent to the parameters\_types
parameter of the @function decorator.
## method output\_schema()
```python theme={"theme":{"light":"light-plus","dark":"dark-plus"}}
output_schema(
*args: Any,
**kwargs: Any
) -> tuple[dict[str, pixeltable.type_system.ColumnType], list[str]]
```
Specify the dictionary returned by next() and a list of unstored column names
**Returns:**
* `tuple[dict[str, pixeltable.type_system.ColumnType], list[str]]`: a dictionary which is turned into a list of columns in the output table
a list of unstored column names
## method set\_pos()
```python theme={"theme":{"light":"light-plus","dark":"dark-plus"}}
set_pos(pos: int) -> None
```
Set the iterator position to pos
