    split0.Trim(KwArgs{"start_frame": 10, "end_frame": 20}),

    Overlay(overlayFile.HFlip(), "").
    DrawBox(50, 50, 120, 120, "red", 5).
    Output(TestOutputFile1).
    OverWriteOutput().

view

function view generate mermaid chart, which can be use in markdown or view online

split := Input(TestInputFile1).VFlip().Split()
	split0, split1 := split.Get("0"), split.Get("1")
	overlayFile := Input(TestOverlayFile).Crop(10, 10, 158, 112)
b, err := Concat([]*Stream{
    split0.Trim(KwArgs{"start_frame": 10, "end_frame": 20}),
