How to Create Picture-In-Picture Podcasts

Podcasts are an effective tool for social media, marketing and technical communication. If you are an experienced podcaster, or have decided to set up your own video blog or for some other reason need to create some content and share it over network, you might be interested in possible ways to do this. Picture-in-picture podcast is an unusual and effective communication means which is very suitable for multiple purposes.

If you want your viewer to see video from two different sources simultaneously, a picture-in-picture (PIP) mode provides this possibility. Meanwhile the first picture is displayed as the full screen, the second picture can be viewed in a small window in the corner of a screen. Picture-to-picture podcasts are suitable for deaf or hard of hearing viewers. They can watch a sign language interpreter in this small window. Another possible application for such podcasts is a presentation that is accompanied with a narrator.

It is explained below how to organize dual-source podcasting using image capturing equipment. Let’s assume we need to make a podcast with the requirement that video content should be taken from two sources. The first source is a laptop used for streaming a scientific presentation.

The second one is a video camcorder shooting a narrator’s video. Both the presentation and the comments are saved on a Mac workstation. To capture the presentation in a high resolution and transfer it to Mac we used the DVI to USB frame grabber which was connected to the laptop and to Mac. To capture camcorder’s video you can use a video converter (analog or DV, depending on your camera).

QuickTime X Player has been used to capture both feeds. This player features a functionality of capturing video of the Mac screen. You should open two separate QuickTime X sessions and save both the narrator’s video and the presentation. After recording the files you can create a picture-in-picture podcast.

Making podcasts is easy using Podcast Producer 2 software. This software should be installed on your Mac workstation. Podcast Producer 2 records podcasts of different formats and uploads them to a server. Then you can publish your podcast to the Podcast Library or a blog.

If you want to create a podcast with two separate streams of video, frame grabbers are a good tool to get advantage of. Capturing content from DVI and VGA outputs of laptops and projectors will not be a problem.

Playing a video in full screen while having another window displayed in smaller size makes your podcast more attractive and helps to solve multiple tasks that otherwise would remain unattainable.
