Specify how you want MediaConvert to determine the fragment length. Choose Exact to have the encoder use the
exact length that you specify with the setting Fragment length. This might result in extra I-frames. Choose
Multiple of GOP to have the encoder round up the segment lengths to match the next GOP boundary.
