Avid has a series of 14 tutorials for editing on their Avid Free DV software.
The tutorials cover all the basics of Free DV, which is a fantastic free version of Avid’s professional editing offerings. Free DV is amazingly well stocked with features for it’s lack of a pricetag (the next version up being $495!). Even though it’s ability to output is limited to Quicktime, it presents a fantastic introduction to the confusing interface of Avid.
Because the entire Avid platform is an industry standard for editing – it is used in major productions such as Lord of the Rings, the presence of these tutorials is great for those who are looking to get a basic primer in professional editing applications (and I’m sure they’ve already been used by some going into this field).
