Thanks for the tip. I’m using GH3. My videos are in the process of rendering and the 2 hour video is taking more than 6 hours to complete. So I’ll try the tip when the video is done rendering. Meanwhile I found that in Vegas Pro 15 by using Device Explorer I can import all the 4GB clips from the sd card as one large file, which solves my problem.
Your tip is good for if I have copied the clips to my hard drive and deleted them from my sd card.
