You'll know if the subject of this book appeals to you and if it does, you wont regret buying it. I'm sure it will go out of date pretty quick but at the moment its essential reading for anyone encoding video for the web.
There's one or two printing errors and all the pictures are in shabby black and white. The front cover shows there's hardly been much attempt to make this book pretty. But all that doesn't matter - Its easy to read and it's packed with essential tips, encoding settings and good suggestions.
All the info in this book is probably on the web somewhere but its great to have it all in a book. It gets you away from that computer screen for change!
