That particular animated .gif was created in a program called Techsmith Camtasia Screen Recorder and Video Editor

ScreentoGif is also a very useful screen recorder which I often use.

Here’s a useful YouTube video to watch to give you a quick idea of it is used.



Both have a learning curve as with all software, but are useful tools when mastered in education and tutorial scenarios.
Both take a little time to get to grips with, but the results, quality wise, can be very good in my opinion.
There has to be a trade-off though with quality and size when showing animated GIFs in online forums. The recorded capture size window, FPS (frames per second), length of recording (in terms of seconds/minutes) and the resulting created GIF and kB/MB size (after editing) is also major factor.

Different browsers have a part to play also when using GIFs. Modern browsers that use ‘similar’ standards are not so much an issue these days, but the likes of Internet Explorer versions render animations terribly and they can show very slow in comparison to say Firefox/Google etc.
It’s only when you see an animation you have created and uploaded to say a forum, on someone else’s machine using their browser of choice, that you see how embarrassingly bad they ‘can’ look to ‘others’.
