I have noticed that I when I add a larger media file than I usually use it will lag a lot and make editing harder. I usually edit a 30 or so minute clip when I edit. I decided to import one of my bigger video clips in to edit this morning as I have a full day to do what ever I want and i noticed it lags a lot and it is harder to get the section I want to edit and get what I want from the clip. Any suggestions as to how to maybe relive some of the laggy issues. Its about a hour and a half long clip and I also have a two hour clip I will be editing as well and expect a harder time editing that one too.
