How can you adjust the speed of a video clip in Premiere Pro?

Adjusting the speed of a video clip in Premiere Pro can be achieved through the 'Speed/Duration' option. When you right-click on the clip and select 'Speed/Duration,' a dialog box opens, allowing you to modify the playback speed of the selected clip. You can increase or decrease the speed by inputting a percentage or by changing the duration directly. This functionality is pivotal for creating effects like slow motion or fast motion, which are common in video editing.

The other methods do not directly alter the speed of playback. Changing frame size affects the resolution but has no impact on the speed. Selecting 'Compress' is not a standard option for adjusting speed within Premiere Pro. Dragging the edges of the clip adjusts its length on the timeline but does not inherently change the speed unless you also set the speed in conjunction with time remapping or similar techniques. Hence, accessing the 'Speed/Duration' settings is the most direct and effective method for speed adjustment.
