Grabilla might be the one for you…

It gives you:

• Screenshots with editing capabilities (unfortunately, not blurring).
• Creating screencasts including voice.
• Animated GIF creation.

It works on Windows, Mac and Linux as well…and it’s free.

It has a user manual and an options window…with the ability to set hotkeys, where to save or publish. You can capture a defined area (rectangular), a full screen, or a program window, but no codec settings for enhanced quality. You can enter text or add an arrow, rotate the image and highlight part of the capture.

Grabilla’s website displays linkage/embedding options useful for posting on the net.

You might have problems capturing video, though.

The download page offers two choices. One is via the site – and I would advise choosing that way since the second is via c|net’s Download.com. If you choose that option, you should pay careful attention not to get ‘wrapped’ software.

As always, before installing ANYTHING on your computer:

1. Do your own research about the software.

2. Determine your need.

3. Create a restore point in case anything goes wrong during the installation.

4. If you haven’t done a backup within the past week, do one. It’s painless and saves quite a bit of regret.

5. Always choose "Custom" or "Advanced" installation if offered. That will allow you to view whether the software comes in a wrapper with toolbars, home page and search engine switchers or other software/Adware you might not want.
