Mouki is a key and mouse screencasting tool designed to help streamers visualize their creative process (hotkeys in particular),
or anything else that requires input visualization.
And even better, it's free!
If you find it useful, feel free to slip me a little something though! :)
By overlaying the inputs visually on the main screen there is no need for messing about with chromakeying in streaming software for optimal results.
Modify the settings to your needs. Fast or slow fades. Adjust margins or spacing as you see fit.
Select the colors to suit your needs. Keys, Text, and Secondary Color have their own selection options.
Display the output where you like! Top, bottom, left or right...it's up to you.
