OT: The Reason Why DV Stinks at Keying
Pretty much anyone who keys DV video will tell you that it’s a right royal pain. So why is it so tough to key?
The answer lies in 4-1-1 color space, which is part of the process the DV codec uses to encode the video signal.
If you’re not technically inclined but are still curious, Alex Lindsay of DV Garage has an excellent, non-technical explanation.It’s part of the MacBreak series of podcasts, and the episode’s title is “The Road to 1080p (part 2)”.
Simply google the above information, and you’ll be sure to find it.
Then you too will know why the DV codec treats your camera’s lovely blue-or-green screen pictures the way a baby treats a diaper.
