I have a shaky video and need to make it less shaky- however when I select the feature I get this red line thru my video about the 'stabilizer needing clip dimensions. create a new project.'
I have one about 35 second video, I'd like the entire thing to be fixed.
You must be using Premiere Elements 13/13.1 and its Shake Stabilizer.
The Shake Stabilizer will not stabilize a video whose properties do not match those of the project preset.
You would need to take the video into a new project with a project preset to match its properties and then
video stabilize the video with the Shake Stabilizer in that new project.
Please review the Adobe document on the Premiere Elements 13/13.1 Shake Stabilizer
especially the part on the Recommendations for Using Shake Stabilizer.
The following blog post evolved around this issue for 2.7K for which there is no Premiere Elements matching
Also note the comments about Shake Stabilizer and Time Remapping cannot be used on same clip as well as
Shake Stabilizer and Time Stretch cannot be used on the same clip.
