Is there any good way to fix focus breathing in Sony Vegas? Had the camera on autofocus and there are a few spots where the camera jumps in and out of focus, didn't see it while filming. I shot locked on a tripod, so the scene is otherwise stable.
I tried using video stabilization with no good results. Loss of focus is not the worst part of the problem, but the camera zooms in closer for a split second then back out.
@Jeffery-Yentzer - I feel your pain. Take a deep breath….. I don’t know of such software? Could that “split second” be part of a Transition, from one moment to the other? Is there any B-roll you could utilise?

I was going to buy a cheaper lens with focus breathing, so I searched out how it could be dealt with. Bookmarked this video at 7:40 
It uses the free Davinci Resolve with it's stabilization modes. Sounds like it depends on each scene as to how well it will work or what mode to us. I got the more expensive cinema lens and have not tried with Vegas (translation mode) or Resolve
@Former user - Thanks for the info!
Thanks for this good tip.
I tried installing Davinic resolve, but it won't run on my computer. Looks like GPU is not compatible.

No B roll unfortunately, just one shot locked on tripod the whole time.
One possible solution is to export the problem frames as an image sequence.
Then you can test if it’s possible to fix the focus breathing / unsharp frames using TOPAZ Sharpen AI.

Or, if the focus breath is short enough, you could attempt to use the warp flow transition.
I love Topaz Sharpen AI and use it regularly for my stills but I doubt that it would be a great tool for fixing focus breathing where the change of focus in an uncorrected lens gives the appearance of zooming on the scene. The following video does a good job of explaining this effect.
If I were attempting to fix focus breathing in Vegas, I'd try pan/crop and key frame the event.
