What is the significance of YouTube keyframe distance in video processing and how does it impact the overall quality of the video content?

The YouTube keyframe distance is the frequency at which keyframes are placed in a video. Keyframes are important reference points for video compression and playback. A shorter keyframe distance means more keyframes, resulting in better video quality but larger file sizes. A longer keyframe distance reduces file size but can lead to lower quality, especially in fast-moving scenes. Therefore, adjusting the keyframe distance is crucial in balancing video quality and file size in video processing.
