## SelectRangeEvery

`SelectRangeEvery` (clip, int "every", int "length", int "offset", bool "audio")

This filter is available starting from v2.5. The filter selects length number of frames every n frames, starting from frame offset. Default values are: Select 50 frames every 1500 frames, starting with first selection at frame 0. (every = 1500, length = 50, offset = 0).
Starting from v2.55, `SelectRangeEvery` will also process audio. To keep the original audio, use audio = false.

Examples:

    # Selects the frames 0 to 13, 280 to 293, 560 to 573, etc.
    SelectRangeEvery(clip, 280, 14)

    # Selects the frames 2 to 15, 282 to 295, 562 to 575, etc.
    SelectRangeEvery(clip, 280, 14, 2)
