Hi Beth
We use both Adrenaline and Discreet Edit 6 here.
Like everyone has said, both systems have their good and bad points, and you will have a period of adjustment to make.
I learnt originally on an old AVID system, then Edit 6 then Adenaline, so it was somewhat different for me.
The big benefit with the AVID is that it has more features/effects than edit, and also that the AVID “language” is a an almost universal one, with only minor operational differences between each variation.
You will find it relatively easy to change if you map the AVID to perform functions as they would in edit, and there are some things like selecting and deselecting all tracks that are similar. Where u will find a big change is in not having a specific “title” or “motion effects” track, and indeed the whole workings with effects is considerably different.
Anyway u will have a whole bunch of folk here on the cow, who have used both systems and will be only too happy to help
Good Luck and welcome to the world of AVID
