How to blur portion of the recording?

Jan 11, 2012 9:45 PM

Tags: #blur #highlight_box

I recorded a software simulation (automatic, demo), and want to blur the URL in the address bar.

 

According to Adobe Help, the blurring effect can be applied by adding a Highlight Box and configuring the Shadow property. I did following the instructions, but I didn't see the Shadow property of the Highlight Box.

 

I'm using Captivate CS5. Is this feature only in CS5.5?

 

Shadow

 

Enable
Select the check box to apply shadow to the highlight box.

 

Direction
Select the direction: inner or outer. The preview of the selected direction is displayed on stage.

 

Presets
click one of the images in Presets to apply a shadow with standard angle, distance, blur, and color settings. You can customize these settings using the appropriate options in the Shadow accordion.

 

Color
click to select a color for the shadow. Specify the alpha for the color, in percentage, in the adjacent field.

 

Blur
Specify a value, in pixels, for the blur of the shadow.

 

Angle
Specify the angle for the shadow.

 

Distance
specify the distance, in pixels, at which the shadow must be displayed.

    You can apply blur to an object in Cp5 by going to the Effects tab then selecting Filters > Blur.

    Yup.  There was a lot of comment when Cp5 came out about the "treasure hunt" required to find this little goodie.

     

    In Cp5.5 they turned it into a smallish button with the words Add Effect to give some clue as to its purpose, but it's still right at the bottom left "dead corner" of the Effects panel.  I've NEVER quite understood the rationale for this placement given that there is plenty of room up on the bar at the top of the Effects panel for it, and all the other controls are up there as well.

     

    I guess I just wasn't meant to be a software interface designer...

    What exactly do you want to blur? The Highlight box default settings are Alpha = 20% which is very transparent? And how did you check the Blur: it will only be visible when previewing, or using the Live Preview button in the Effects Panel. Be sure to extend the duration of the Blur effect for the duration of the object you are blurring.

    Actually, instead of blur I prefer to use pixellation.  If you happen to have SnagIt on your PC it has a very nice little filter for this.  Just export your background as an image (or right click in the library and select Edit with.. to choose Snagit as the editor), select the area of the URL you want to make unreadable, and on the Image tab go to Filters > Pixellate.

     

    When set to 3 the pixellation looks like this:

    I would just do one pixelated version of the URL and then copy that over the top of the clear one on each slide where it occurs. Then use Merge Into Background to make it part of the background image.  Much quicker.

    Hi there

     

    Hopefully Rod won't mind my adding the following tidbit.

     

    Before performing the Merge into Background, I'd position the first one accurately, then copy that and paste onto the other slides. It's likely that the URL will appear in the same X Y coordinate on the other slides. By positioning first, when you copy and paste, the image should be already perfectly placed on the subsequent slides.

     

    THEN I'd do the merge into background hokey pokey.

     

    Cheers... Rick

    After looking at your video I can tell you that this will have very little effect.  You're placing a highlight box over the top of your URL in the address bar and setting a default blur on the highlight box.  The default transparency setting on the highlight box is about 20%.  So any effect applied to it would only be about 20% visible anyway.  Additionally, applying a blur to the highlight box isn't going to do anything to the URL underneath.

     

    In your video you didn't follow the steps you outlined in your previous post where you actually edited a portion of the background image using SnagIt's pixelation filter.

     

    The Blur filter effect DOES work in Captivate, but you have to use it properly, and you need to recognise that it does NOT work the same way as it does in SnagIT or other graphics editors that allow you to select an area of a graphic to be modified by the blur.  In Captivate the Blur effect is performed using AS code at runtime, and only gets applied to the entire OBJECT.   If you really want to see a Captivate blur in action, add a text caption to the screen and apply the same Blur filter to that.  When you publish you will see the entire text caption is quite effectively blurred. 

     

    But this blur effect is actually a filter applied to the SWF at runtime.  So you cannot just use SnagIt to just capture the URL in your address bar and then import this captured URL as a graphic file into Captivate, apply a slight blur filter to it to make it unreadable and then copy/paste this graphic to Merge with Background.  This approach won't work.  That's why we suggested you apply the blur or pixelation in Snagit first and then import the modified graphic into Captivate to apply over the top of your URL.

    Are you referring to the section on this Help page that refers to how you can configure a Shadow to have a specific Blur value?

     

    If so, I don't think the documentation is misleading, but I would agree that documentation specifically about how to add a Blur effect is missing from the help file and probably should be added.
