About K-Frames

The left and right arrows move to the previous or next K-Frame. K-Frames are significant points of transition in a video file - usually the start of a new scene or camera shot. Moving between K-Frames is an efficient way to locate important segments quickly.

Here's the technical side of K-Frames. Video files are a series of images. When video files are compressed, rather than compressing each image in the video, some images are calculated as a difference from the previous image. If there are several seconds with little movement, for example, rather than saving each frame of the same image, the video compressor just saves the differences between each frame, which may be small. This leads to efficient compression. However, there are times when two adjacent frames are very different, such as a new camera shot. In that situation, an entirely new starting frame - the K-Frame - is brought into the compression process. Ensuing frames are again calculated as differences from the K-Frame.
