Setting keyframes in the timeline is accomplished by hovering over the grey line between the two keyframes until your cursor turns black with two little arrows (up and down) beside it. This means you will now by moving that line. If you pull the line down, you will make the portion between the two keyframes play slower. If you pull it up, you will make that portion play faster.
This ONLY affects the VIDEO portion of the clip, however. Audio is not affected by Time Remapping in Premiere Pro, although it is affected when doing a similar thing in After Effects. While this works well, if you play the clip you will notice that the speed change is very abrupt. Users also need to ease the change in speed when editing. That way you keep the viewer in the story, not distracted by the shortcomings of the technology.
This is where the keyframe for Speed Remapping differs from any other type of keyframe, because these keyframes can be SPLIT to add easing. To do this, simply click and drag on one side of the keyframe to create the split. The longer the split, the greater the easing.
Note that there is a little set of blue handles in the middle of the sloping line. By moving these handles up or down you will be change the easing as the handles affect the shape of the line. Every Time Remapping keyframe can be changed this way for super smooth changes in speed.
