How did I make this Screencast:
Prepare, collect images and text. You need microphone and screencapture software. (I use Snagit, JING is a free video capture program) Resize pictures to fit in capture.
Open image #1 on screen.
Open Snagit and capture image on video. (add voice when capturing)
Open image #2
repeat until end
Now stop Snagit and safe file.
Upload file (mp4) to Vimeo and wait until the video is processed. Embed video (Vimeo has Help to explain embedding).
(Any other website to upload your video is OK, Youtube, Screencast.com, etc.)
GIMP is here
