z_ConvertFormat(pixel_type="YUV420P16",colorspace_op="601:601:709:l=>709:709:709:l",resample_filter="spline36", dither_type="none")
Subtitle("""z_ConvertFormat(pixel_type="YUV420P16",resample_filter="spline36",""" + """\ncolorspace_op="601:601:709:l=>709:709:709:l", dither_type="none")""", lsp=1)
Code:
ColorBars(pixel_type="yuv420p16")
Import("TransformsPack.v1.0.RC1.avsi")
ColorSpace("601","709","spline36","spline36",true,false)
Subtitle(""" ColorSpace("601","709","spline36","spline36",true,false) """)
