    • 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)
    • Top five video podcasts (from Podcast Alley)

        • “ News about tech tools and toys”
        • “ Fast, fun, fresh and flirty”
      • Launched on 23 December 2005
      • Presenters quit their day jobs after five months

    • Creating video podcasts
      • Audio and video sources:
        • Digital camera / camcorder
        • Webcam
        • Mobile phone, etc.
      • Access content:
        • Transfer video files from device
        • 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
    • VirtualDub screenshot
