The Advanced Settings field adds additional fields to run your frame capture. Just select the Advanced Settings checkbox.
There are four additional fields in the Advance Schedule Frame Capture window. The steps to set a schedule are the same except you need to set the additional fields. There is a Capture Size Limit (frames) field where you can set a limit on how large the captured frame file can grow.
The three other fields are used to truncate the captured frame file for captured:
If you want to truncate any of the above frames, place a checkmark in the checkbox next to field that you want to truncate. Then, move the slide-bar to make your adjustment. Moving the slider to the left reduces amount of bytes to capture. Moving the slider all the way to the right sets the field to no truncation.
If you remove the checkmark from the Advanced Settings checkbox, you are returned to the original Schedule Frame Capture window.
