David Vincent Clarke has created a whole heap of video tutorials on EDIUS.
There are complete collections for sale on his DVC.UK.COM site.
He has also created a number of very useful FREE tutorials on EDIUSwhich can be found HERE.
When I was beginning to get into EDIUS one of my personal favourite tutorials by David was THIS ONE
Although DVD UK ceased trading from Friday 10th March 2017, David has promised to keep the majority of his online Tutorials active. I am leaving the links to the left as they are.
If I notice that any links "die", I will try to find out if David has any other links that I can post instead.
His work is too valuable to cease to be available.
