The workflow begins with shooting in HDV 1080i.
Before getting into the encoding process let me give everyone a tip on shooting - TRIPOD!
No matter how difficult it is try and use a tripod for all your shooting. You will never be able to use it for every shot, but I am certain you can use one more than you are doing today. No amount of image stabilisation or de-shaker software can compete with the footage obtained by using a good quality tripod!
