As surely as day follows night, video follows audio. The increasing popularity of podcasting, both as a distribution channel for audio broadcasters and as a 'radio-show' delivery manager for subscribers, inevitably means that insatiable techies will turn to video as the next medium to 'podcast'.

'Video-podcasting' isn’t the right name for this newly emerging phenomenon. Video files can’t be viewed on iPods. Not yet.
'Video-casting' (for want of a name) is all about creating a video production, inserting the resulting digital video-file (via enclosures) into an RSS feed, then making the RSS feed discoverable, by submitting it to a feed directory.
As a ‘video-cast’ subscriber, you search the directories for potentially interesting shows, select those you wish to follow - and as soon as a new show is made available online, you get notified (email, RSS feed, IM message). You then click on the link to the video-file in the notification message and download the file to your computer – to be watched in your browser at your convenience.
So, does ‘video-casting’ have the potential to become the blogoshere’s ‘next big thing’ and will it evolve into something much bigger than ‘podcasting’?

Quite possibly.
As information consumers, we like audio, especially for receiving news.
But don’t we prefer video combined with audio? Like in a TV show? Well, perhaps in certain contexts, such as for news programs, documentaries, chat shows (you have to see their faces for the best effect).
Audio broadcasts are great when we’re listening-to a podcast via our MP3 player, say while driving. Video-casts are, at least for the time-being, better consumed at the desk-top. Soon, inevitably, you'll be able to view them on your mobile phone.
But it is on the production-side that video has the advantage of audio. Quite simply, it's easier these days to produce video that audio. Mobile phones are increasingly integrating video-recording facilities into their camera features. Web cams and video-cameras are proliferating as the technology gets better and the prices fall.
The recent catastrophic Indian Ocean tsunami is witness to this phenomenon - an enormous number of amateur videos recorded the event, as it happened, and these were then made almost instantaneously freely available over the Internet. The demand to view this footage has been colossal. Over the course of January 2005, Robin Good's collection of much of this footage received over one million page views.
To date, where audio podcasts have had the advantage over video-casts has been in their ease of distribution and consumption. Once you've made an audio recording, you simply submit it to one of the podcast directories, such as iPodder.org or the recently launched The Podcast Network.
Consumers need only to find your audio-file on the directory to be able to download it there and then to listen to (either on their computers or MP3 players). Or they can subscribe to an RSS feed of your recordings and be alerted whenever you make a new one available. This has not been really achievable, up until now, for video-casts.
Here are some useful links on podcasting:
A number of new tools and applications have recently been launched which will help to catalyze the popularity and development of video-casting.
Video-cast Production
Visual Communicator is a:
"simple-to-use, affordable software solution that makes it a snap to create your own polished video news broadcasts in minutes instead of hours.

It even gives you the power to create once and then distribute via websites, video tape, CDs, DVDs and more. With Visual Communicator, you can create "the look of Prime Time" ...in no time."

Video-cast Distribution
ANT (currently only available for Macs but with a Windows version on the horizon), is:
"An RSS video aggregator and media player currently available for Mac OS X 10.3 Panther.
With ANT, you can subscribe to any RSS 2.0 feed with enclosures. ANT will automatically download fresh audio and video content for you to watch and listen to. It can playback any media format, and even syncs audio files with iTunes so you can easily add them to your portable MP3 player.
ANT is a stage that allows anyone to share their original video creations -- from personal video journals made by an emerging community of videobloggers, to the growing ranks of distributed citizen journalists, to home video simply intended for friends and family."

The increasing popularity of Video-blogging, or vlogging, will also help to drive the growth of video-casting.
From the same stable as Serious Magic's Visual Communicator comes Vlog It!. Previewed at the DEMO@15 show and soon to be released, Vlog It! claims to be:

"the first PC software designed specifically to help you create the most powerful kind of blog – a video blog. Even if you have no video experience or technical skills, Vlog It! makes it easy.
Just place a webcam or camcorder on top of your monitor and connect it to your PC. Vlog It! gives you an on-screen teleprompter just like the newscasters use so you can vlog quickly and confidently. Just type in your notes, hit record and read. It'll look like you're staring into the camera as you read your notes. You can even pause the teleprompter for the ultimate form of self-expression—the tangent.
You also can instantly drag and drop still pictures, video and sound clips from your camera, camcorder or cell phone. Simply slide the image or clip alongside your notes until it lines up with the correct words. Placing your stills and clips next to the words you're going to say causes them to automatically appear on-screen when you reach that point in your vlog. No director or crew required!"
In fact, Userplane AV Blogger got in on the act first, as reported here.

The pieces are coming together to enable video-casting to be the 'next big thing'.
Start creating.
