Applying Premiere Pro’s Warp Stabilizer to multiple clips can be a time-consuming and frustrating task. This is because you cannot select all the clips you want to apply the effect to and drag it on all of them, as it will take the average motion in all the clips and stabilize them on average instead of treating each clip separately. Additionally, sometimes Premiere Pro’s Warp Stabilizer fails without giving any error message. To address these problems, the Automator Plus Warp Stabilizer automation was created.
The automation allows you to add a Warp Marker to the top of each clip if you want to apply the Warp Stabilizer. You can then execute the Apply Warp Stabilizer automation, and it will go through each of the tagged clips and apply the effect in isolation. This means that you can walk away from your PC and come back to find all the clips you’ve tagged to be stabilized.
However, what about the clips where Premiere Pro’s Warp Stabilizer fails? In such cases, a Warning Marker is added above those clips, so you are aware of them. Note that the automation checks how long it takes for the Warp Stabilizer to apply, and if it’s less than five seconds, it is usually an indication that the application failed. This can lead to the automation always tagging short videos that have Warp Stabilizer applied as a failed application, as the application takes less than five seconds.
To use the Apply Warp Stabilizer automation, several arguments are defined in the code. The “Which Clips” argument allows you to choose where you want to apply the effect. You can choose to apply it to the clip at the player head, to all clips that have effect markers above them, or to all clips on the selected tracks. The “Which Tracks” argument allows you to select the tracks you want to apply the effect to. You can choose to target the topmost visible clip, target the clips on targeted tracks, or apply the effect across all tracks.
The “Result” argument is a dropdown selection that allows you to choose the result of the Warp Stabilizer effect. The options include “Smooth Motion,” “No Motion,” and “Subspace Warp.” Lastly, the “Smoothness” argument allows you to set the smoothness value for the Warp Stabilizer effect. It is an integer value between 0 and 1000 and cannot contain decimals.
Before and after applying the effect, the automation performs several checks. Firstly, it checks whether the selected clip has any speed changes, and if true, it will nest the selected clip. Secondly, it checks whether the selected clip has the same pixel aspect ratio as the sequence, and if false, it will nest the selected clip. Lastly, before moving on to the next selected clip, the Warp Stabilizer will first complete the stabilization of the current clip. If the automation detects that a clip was incorrectly stabilized, it will add a warning marker so that you can manually check the stabilization.
