How to Create Podcasts From Different Video Sources

Podcasting is an innovative technology that is receiving currently a great deal of attention. This nifty tool empowers you to distribute on the Internet video or audio files. Your audience can download and view your podcast on computers or mobile phones. Besides when someone is subscribed to a podcast, it is delivered to their devices automatically and there’s no need to do anything to get it. Let’s assume you have already concerned yourself with your goal, your key messages and audience.

What equipment do you need to create a podcast? When we talk about an audio podcast, one should record an audio program and broadcast it over the web. The required equipment is computer with Internet access, microphone and recording software. Video podcasting is good for delivering visual information or for showing something you wish your viewers could experience in the way you’re experiencing it. Undoubtedly, with this sort of podcasts the technology is now entering whole new level. If you are creating a video podcast try to use feed from multiple sources to produce interesting content. Here’s a simple and efficient schema of how to do it. In this example the content is taken from a camcorder, PowerPoint slideshow and some materials captured from an iPad screen. To capture video from these sources the VGA2USB LR frame grabber has been used.

Before you start podcasting make sure you’ve properly installed all necessary hardware components and software for editing footage. To upload your video to the web you need a target computer with application for live video streaming production. It allows you to broadcast events and include them in your podcasts. In this example Wirecast application has been installed on a computer. Further to its streaming capabilities Wirecast can process feed from multiple cameras. Other media (such as movies and images) can be mixed too.

Video footage from the camcorder is saved on a computer. Frame grabber captures iPad screen and PowerPoint slideshows. Before using it you need to install free software from the Epiphan’s website on the computer. This software enables configuring image settings to provide accurate output of the captured feed. Alternatively you can use a tweak for the iPad for this purpose. The tweak (“Display Out”) can be installed from Cydia. After installation it is displayed in the Settings app and you can make necessary image adjustments. iPad is hooked up to the frame grabber using the iPad Dock Connector to VGA Adapter. The frame grabber transmits the data via the computer’s USB port. The iPad should be jailbroken.

VGA2USB LR is also used to capture a PowerPoint presentation so that you could add it to your podcast. This frame grabber uses the VGA output for capturing the video feed. VGA2USB LR is connected both to the VGA port of the computer with PowerPoint presentation and to the target computer’s USB port. The podcast has been produced using three video sources: camcorder, iPad and source computer with the slideshow. Since you have prepared the video content, let Wirecast create a video podcast and broadcast it to a website.
