This is an answer I found on the adobe forums after googling it: The keyframe distance is the maximum number of frames before the encoder inserts an i-frame, which is the highest-quality frame of an MPEG stream (ie, it has all the information for a single frame of video inside of it rather than relying on the frames around it to reconstruct ...
WebSep 1, 2016 · Most encoders use fixed number of frames in a GOP as it is easy to implement, but it affects coding efficiency and also visual quality.

WebVideo encoding refers to the process of reducing the size of video files and streams as well as converting them into different formats for distribution. Video encoding is often used interchangeably with the term transcoding. But, they are not necessarily the same, which we will delve deeper into and explain later on.
