Grzegorz PastulaHow to censor/hide area in the video

Hi everyone,
This is my first post here. I've watched Adobe's "How to hide a face"
and now I'm able to hide/censor an area inside the video only when it's not changing it's size. When the object in the video gets bigger, I don't know how to do it. Can anyone give me a tip on how to change the mosaic scale so for example, in the first 30 seconds it's 20.0, 20.0% and then enlarge it to like 40.0, 40.0% ?

I hope you know what I mean. If you watched the mentioned adobe tutorial video - it's easy to do because the guy's face stays the same size during the entire clip, what if the guy walked closer to the camera ?

Thanks in advance !

That video that you linked to is a bad video. Yes, I know that it's on our website, but it's still not a good introduction to how to do this kind of thing.

Here are a few much better videos that show how to do this kind of thing:
(This shows a color-correction effect, but the same technique could of course be used for a blur, etc.)
