Any way to correct autofocus "breathing"?

Like an idiot I left AF on while shooting video with my DSLR.  The DOF was shallow enough that when the subject moved a few inches in either direction the AF would change.

Here's an example of the hideousness:  https://youtu.be/idY_yjO8jcE

I know I'm not going to get the subject sharp, but it would help a big if I could make it so the background remains the same.

I'm thinking that I could ease in/out a slight scale to try and keep the bg relative

I think you could fix this with a couple of methods... You could try roto brushing out the background in AE.... then replace it with a content aware fill background made in Photoshop.   Here is a tutorial from youtube on rotobrush... https://www.youtube.com/watch?v=XNRnrsmDPJs  and here is a tutorial on content aware fill https://www.youtube.com/watch?v=OiwqOAPE0kk.   

1) Take a screen grab from your video with background you like

2) open in photoshop and content aware fill it so you have a clean background (use clone stamp and healing brush to add details)

3)save this as a new background

4) In AE Rotoscope the background out (see tutorial)

5) replace background with Photoshopped background...

 

Hope that helps... there are lots of different ways to do this, but this is pretty good. 

With the new Content-Aware Fill workspace in Photoshop CC, you can change the selected source and adapt content based on rotation, scale, and mirroring.Get P...

Here is screen grab of your video with new background (image 1) and the background I made in photohop with content aware fill (image 2).  I did not spend a lot of time cleaning them up and making them perfect, but you get the idea.  Thanks.

Wow -- reading that at first sounds like an insane amount of work, but after watching the AE Tutorial, it doesn't seem that bad!

I'm going to try this, thanks!

I've had success with warp stabilizer completely covering up pretty fast moving focus hunting.
