Screencasting -share your screen
Posted by: mberner In: Instructional Video| Podcasts| Screencast| Web 2.0
A screencast is a digital video recording that captures actions taking place on a computer desktop. Screencasts, which often contain voice-over narration, are useful for demonstrating how to use specific operating systems, software applications or website features.
Screencast production requires some kind of video-capture software and a microphone. The software, which can be a desktop client or web-based service, captures and synchronizes the video and audio files and compresses the completed movie into a format that can be shared.
Screencasts are an effective way of making tutorial videos. These videos can be shared on a ning, wiki or blog, or uploaded to Youtube. you could also upload your screencasts to a podcast hosting site like podbean.com or gcast.com to enable users to subscribe to any of your new content.
What do you need to make a screencast?
- Screen capture software. There are some free programs – these will be discussed in this post or if you are looking for commercial software, use Camtasia Studio.
- A digital microphone and headphones. Don’t use the computer’s built-in microphone as it gives poor soubd quality.
