[sathees]

Hi any one knows how to make silhouette get start frame from 'Footage' itself. Example my shot start with the frame no 1001 and when ever i start new session silhouette sets the start frame as 1. I need to tell the silhouette to get the starting frame no from input. I know it can be done by some simple python script..... Is any one make it work..
