Ok, i wanna do batch rending jobs in my vagas 4b as its very frustrating to sit around doing nothing when im rending a job in vegas 4.. i noticed that there are some mark options and someone told me that it automatically splits files if you sellect the whole project along with marks in between, with this i can leave my pc alone.. and let vegas do the batch rending for itself... is it true?

If it is then please tell me.. as i want to use that option.. i work in heavy file invironment and when it requires different video clips so if i keep sellecting each clip and rending it to a file.. its takes a long time.. but if i wanna do the whole 75min project and but some option in between so it can split files like 3 time wherever i want and rename them itself.. (to any name) so i can leave my pc with rending online..

Please tell me how to do this.. !
