Once Warp Stabilizer completes the stabilizing stage, Premiere Pro returns to the normal state.
To help with this, first identify the shaky portion of the footage and then split the clip to isolate those shaky parts. Then, run Warp Stabilizer only on those shortened clips. To split clips, move the playhead to the points in the tracks where you want to make a split. Make sure the channels you want to split are highlighted. If you want to split the audio with the video, make sure the audio track is highlighted too. Splitting and moving the video without the audio may cause your audio to go out of sync elsewhere. If you want to split clips where two or more clips or tracks overlap in a timeline, you’ll need to switch to the Expert View Timeline. Drag a marquee to select clips on different tracks that overlap at a point in time. Then, drag the playhead to the frames where you want to make the split.
Use the keyboard shortcut Command/Control + K (for Mac or PC, respectively) or choose Timeline › Split Clip. Now you have two clips from the same file that can be edited independently. Once the Stabilizer has finished working, you can examine your work and make adjustments to ensure the video features everything you need to see in the shot.
