Avid, the world leader in digital media creation tools, has published a series of guides and resources specifically for those who use (or would like to start using) HD for their video work.

“Understanding HD: Your Comprehensive Guide to High Definition on a Budget”:
“Part 1” “Part 2” “Part 3”

“The Lifecycle of a Project: Shooting High Definition on a Budget”:
“The Camera” “Shooting” “Editing with HDV”

I stumbled upon these resources in ReelSEO’s Tips Section where you will find many other useful articles and resources for filmmakers.
