With the replace edit command in Adobe Premiere Pro you can quickly and easily replace a clip in your sequence with the one you have selected in your source video window. First, simply load the clip you want to switch in to the source video window. Then line up the playheads in both the source video and editing box windows so that the video switches to the clip in your source window at the desired time. Next select the clip you want to replace in the editors box and click on the clip tab on the toolbar. Scroll down to “replace with clip” and select “from source monitor, match frame”. This will replace all the frames from the position of your playhead to the next cut point with the same amo unt of frames from your source video starting at the position of the source video playhead.
