### Segment size

Use this option to divide a huge dataset into a few smaller segments.

|
For example, one job cannot be annotated by several labelers (it isn't supported).

Thus using "segment size" you can create several jobs for the same annotation task.

### Frame Step

|
Use this option to filter video frames.

For example, enter `25` to leave every twenty fifth frame in the video or every twenty fifth image.
