Is there a screenshoter for integration with WP and other "charms"?

Question

ubuntu

Greetings!
I like to write in my cozy blog on WordPress, I often have to insert screenshots, record videos, make animations. But all of the above actions take a lot of time, so I have to add a little bit.
For screenshots, I still use "shutter", it's almost perfect if I could still shoot videos from the desktop and convert them into animations...
So, we are looking for an addition to it and to Wordpress, so that after the snapshot it would automatically load into WordPress, and after loading it could be inserted into an editable post.
Has anyone seen such a combo, or maybe there is software specially tailored for this business?
PS under Linux.
