Which statements on Group of video (GOV) length are true?

The Group of Video (GOV) length setting affects both the bandwidth and storage requirements of video streams. A longer GOV length, which specifies the interval between keyframes in a video stream, reduces the frequency of keyframes, thus lowering the bandwidth consumption. However, it can also increase the storage time on an SD card because fewer keyframes are stored over a given period, making the video stream more compression-efficient.
