18gb for 75 minutes? Is it ok?
 

Hello,
trying to make my first blu ray project.
This is a wedding, captured from ex1r hd xdcam 1920x1080i, edited in avid mc4.
Export with QTRef and imported to TMPGEnc and export as .m2v video and Ac3 audio.(Two seperate files, in order to dont let the Encore transcode again).
I have the following question.
18 GB is it ok for this project?
Thanks
