This is a free computer download that allows you to capture anything on your computer screen and posted to the Internet giving you a URL to be pasted or embedded on your site. You may play videos, show images, show power points within the capture and more.
RH: This capture tool is not for the faint of heart. It can do a lot of things and therefore has somewhat of a learning curve. It is relatively easy to use but has the ability to zoom, draw focus to a spot on your screen, and be edited after the fact. My first experience resulted in a lot of noise in the audio. I don't know if it was because I just used my mic that was built into my laptop or what. The free version limits the recording to 15 minutes but a good screencast should be less than 8-10 anyways. The pay version is only $15 a year and opens up more possibilities. This would be a good choice if you have a lot of content on your computer and don't want to bother moving it to your iPad or can't in order to use an iPad app to screencast.
