# FrameRange

> Sets the clip's frame range with first_frame and last_frame (what the timeline shows with the range source on Input, and what Retime / Kronos take as their input range).

Sets the clip's frame range with first_frame and last_frame (what the timeline shows with the range source on Input, and what Retime / Kronos take as their input range). Pixels pass through; reset takes the input's range.
