Hi Rafael,
thanks for your response. I was using MPEG 4, but I did change the export codec and its working to an extent, in that it is exporting the files now, when the computer doesn’t crash. 🙂
However, the white frame problem persists in the edit itself, every time I stop playing the edit, it rests on a white frame, I am wondering if its because my laptop hasn’t enough power, as it all ran perfectly on my tower.
