Blur less effective on zoom

Very new to Camtasia (as in, used it for the first time yesterday).  I'm hoping there's a solution to an issue I noticed.

The blur effect seems to lose it's intensity if I zoom in.  See this GIF for an example.



I understand the issue - as I zoom, the blur radius remains the same but the number of pixels constituting the hidden text grows - so the same blur radius isn't as effective.  I've been able to get around this by double-blurring, but wondering if there's a fix I don't know about.

FWIW, I think the max blur setting is pretty weak, even before zooming.  If the max blur setting could be increased and the blur radius made to vary inversely with the zoom, everything would work great.

To the best my knowledge, applying a second blur is the best you've got. I don't know why the blur settings to this filter are as low as they are. But it is what it is.

Pixelate seems to suffer from the same problem.

I could just cover it up with a white box and call it a day, but the point of blur and pixelate is so the viewer is aware there should be content on the screen even if you don't want the details known.

It's not a huge issue - I can work around it with double-blur.  Just seems like it the issue could be easily addressed.  Other than that, I'm very impressed with the program - crazy easy to use.

What I typically do is use a callout to cover it and replace the text with something generic. 

This works fine, but there's one issue to be aware of:

Text boxes have a minimum size border that you cannot change. In some cases, it can obscure adjacent text, particularly if the text you're working with is small. What I do to get around this is to make a text box that's several times as large as I need and use an equally large font. Since the border is the same width regardless of the size of the box, this reduces its size relative to the size of the text. I then scale down the text box to the size I need and the problem is gone. 

For example, if I need 16 point text, I'll create a text box with 64 point text and scale it down to 25%.

That's a good idea.  I can envision scenarios where that might even be preferable, as you could give context to the content.  Thanks for the suggestion.

Yes, it allows me to replace names, email address, phone numbers, account numbers, etc. with content that is meaningful, but benign.

group the pixelate callout with the text, then the zoom the group; works fine for me

That's what I've been doing, but no joy.  The pixelate and recording are grouped together, and the zoom is on the whole group.

Made a quick vid trying to duplicate what you did.  I get different results.

AH!  That was it!  I didn't realize that changing the intensity of the annotation wouldn't affect the entire timeline.

Seems like that would work with Blur, too, if I wasn't starting at 100.

Although I don't use blurring or pixelating much, this is good to know!
