Video podcasting recap
Video podcasts are similar to audio podcasts, and can be downloaded to PCs or PMPs
Some television stations are making episodes of series downloadable for free (e.g. C4’s 4oD) or for a fee
There are also many free video podcasts (interviews, news, documentaries, behind the scenes, etc.)
Your own internet TV station…
All you need is a cam!

Video trends
“ Rise of video downloads threatens gridlock on net”
http://technology.guardian.co.uk/news/story/0,,2010131,00.html
“ Despite the relatively small number of users, research indicates that systems such as BitTorrent are responsible for more than 50% of all internet traffic.”
“ Premium Internet video services to reach $2.6 billion by 2009”
http://www.instat.com/newmk.asp?ID=1478
“ With more than half of adults (53% of consumers 18 and older) stating that they view online video, we're witnessing the early signs of mainstream adoption of Internet video.”
Forrester, 3rd October 2006

Difference between video downloads and podcasts
Both video downloads and podcasts can / may have:
Content creation process
Compression using codecs
Multiple file formats
Streaming servers
DRM or restrictive transfer protocols are not usually a feature of video podcasts, or no-one would bother dling
Video podcasting differs in that it includes some mechanism for automated download of video files:
RSS subscription
Blogging or CMS software
Similar publishing to audio podcasting as described last week, and an organic extension to blogging

Automated downloading of podcasts (Stolarz, Felix)
More about RSS in three weeks (content syndication)

Creating video podcasts
Audio and video sources:

Live capture via USB, TV card, etc.
Conversion, compression:
Video codecs
Processing tool, e.g. VirtualDub
Upload to the web (as described last week):
YouTube, Google Video, archive.org, etc.

Some tips
Video needs to be fairly short:
Less than 5 minutes is good
15 minutes is okay
30 minutes is too long
Since a lot of video podcasts are similar to “talk radio”, there can be a bit of a learning curve
Use “podsafe” audio in your videos:
http://labnol.blogspot.com/2006/07/download-podsafe-music-in-mp3-format.html
GarageBand, Magnatune, etc.
To make money, insert video ads, use Google ads at download site, have a PayPal “tip jar”, Revver “RevTags”

Video file formats
You guys probably know more about this than me 
When you get a video file, there’s a distinction between the video file (or the container) and the video (and audio) encoding formats
“ Box types”:
ASF, AVI, MOV, MP4, SWF, FLV, etc.
“ Packing materials”:
Video: WM9, DivX, XviD, Spark, MPEG-4, Sorenson, Real Video, etc.
Audio: MP3, AAC, WAV, OGG, AIFF, WMA, MP3+, AAC+, etc.

VirtualDub video editor
virtualdub.org
“ Proof that I had too much free time in college”
Free video capture and processing utility for Windows
Licensed under the GNU General Public License (GPL)
Streamlined for fast, linear operations over video
Batch processing capabilities for processing large numbers of files
Can be extended with third-party video filters
Mainly geared towards processing AVI files, but can read MPEG-1 and handle sets of BMP images:
There is a modified version that can handle MPEG-2

VirtualDub helps you get video into your computer
If your capture device is Video for Windows compatible, then VirtualDub can capture video with it. But VirtualDub isn't your average capture program:
Fractional frame rates. Don't settle for 29 or 30 when you want 29.97
Optimised disk access for more consistent hard disk usage
Create AVI2 (OpenDML) files to break the AVI 2GB barrier and multiple files to break the FAT32 4GB limit
Integrated volume meter and histogram for input level monitoring
Real-time downsizing, noise reduction, and field swapping
Verbose monitoring, including compression levels, CPU usage, and free disk space
Access hidden video formats your capture card may support but not have a setting for, such as 352x480
Keyboard and mouse shortcuts for faster operation. To capture, just hit F6
Clean interface layout: caption, menu bar, info panel, status bar

VirtualDub lets you clean up video on your comp
There are lots of programs that let you "edit" video. And yet, they're frustratingly complex for some of the simplest tasks. VirtualDub isn't an editor application; it's a pre- and post-processor that works as a valuable companion to one:
Reads and writes AVI2 (OpenDML) and multi-segment AVI clips
Integrated MPEG-1 and Motion-JPEG decoders
Remove and replace audio tracks without touching the video
Extensive video filter set, including blur, sharpen, emboss, smooth, 3x3 convolution, flip, resize rotate, brightness/contrast, levels, deinterlace, and threshold
Bilinear and bicubic resampling -- no blocky resizes or rotates here
Decompress and recompress both audio and video
Remove segments of a video clip and save the rest, without recompressing
Adjust frame rate, decimate frames, and 3:2 pulldown removal.
Preview the results, with live audio
