No, he means key frames, or i-frames, or however you want to call them, as opposed to p-frames or b-frames.

He means to set the encoder to have only key frames / i-frames, and no p-frames or b-frames. This would allow the segmenter to cut everywhere.

it is probably good enough to set gop / "max keyframes" and "min keyframes" to the same value, and have this value be the amount of frames after which you want to cut.
