Step 1: Download “Screen-to-Gif”
This is open-source and free. Also very simple to use screen capture software.
Step 2: Find a good segment you want to capture and press the big ‘red button’ in the top-right corner of this program. You will see this screen:
Which you can position over the content you want to capture.
Step 3: Position the screen over the content you want to capture, and adjust the frame by manipulating the sides with the use of your mouse. Press ‘record’ (or F7) to start recording and then - when finished - press ‘stop recording’ (or F8).
Step 4: Watch your clip, you can now easily cut the frames you do not want or need and trim it to a good size.
Step 5: Save it as a ‘GIF’.
Step 6: Upload it to an online host. GIPHY is very user-friendly and again free. You only need to register to start uploading your gifs. After you have uploaded it, press: “share” (make sure to set your gifs to public) and then copy the link.
